South Eastern Railway (England)

At the time of inauguration there were two potential rail pathways south from London, and the Speaker of the House of Commons had said no further pathways would be permitted.[3] The SER therefore considered routes to Dover from the proposed London and Southampton Railway line at Wimbledon, or from the existing London and Greenwich Railway (L&GR) at Greenwich. The former left London in the wrong direction and then on a roundabout route. The latter provided a useful way for a northern route via Gravesend, Rochester, and Canterbury, except that lengthening the line beyond Greenwich was blocked by opposition from the Admiralty, and this route would involve tunnelling through the North Downs.

The engineer of the new line, William Cubitt, was also engineer of the London and Croydon Railway (L&CR), which planned to use L&GR lines as far as Corbett's Lane in Bermondsey before turning south towards Croydon. A new connection on this line near to Norwood could provide access to a southerly route to Dover via Tonbridge, Ashford and Folkestone. This was less direct than the northerly route but passed through easier country. It involved one significant 1,387-yard (1,268 m) tunnel through the Shakespeare Cliff near Dover. This was the route first chosen by the SER at its inauguration.

During Parliamentary discussions on the proposed route of the London and Brighton Railway (L&BR) during 1837, pressure was put on the SER to divert its proposed route so it could also share the L&BR mainline between Jolly Sailor (Norwood) and Earlswood Common, and then travel eastwards to Tonbridge. Under the scheme proposed by Parliament, the railway from Croydon to Redhill would be built by the L&BR but the SER would have the right to refund half the construction costs and own that part of the line between Merstham and Redhill. The SER gave way to this proposal as it reduced the construction costs, although it resulted in a route 20 miles (32 km) longer than by road, running south for 14.5 miles (23 km) and then turning east. It also meant that its trains from London Bridge passed over the lines of three other companies: the L&GR to Corbett's Lane Junction, the L&CR as far as 'Jolly Sailor', and the L&BR to Merstham.[4]

In 1843, when the railway reached the edge of Folkestone, the company bought the silted and nearly derelict harbour, built by Thomas Telford in 1809, for £18,000.[10] The SER dredged the harbour and, after a trial with the paddle steamer Water Witch, which also demonstrated that a day excursion from London to Boulogne was feasible, arranged for a packet company to provide a ferry to Boulogne.[11] The following year it established the independent South Eastern & Continental Steam Packet Company, which it absorbed in 1853.[10] James Broadbridge Monger was the master of the Water Witch from 1839 to 1844. From 1844 on, he was master of three vessels which steamed from Dover and Folkestone to Boulogne, Calais and Ostend with passengers and cargo: Lord Warden, Princess Helena and Princess Maude. In December 1848 it opened a steeply graded branch from the Folkestone station to the harbour.[12]

The SER opened Dover (later Dover Town) station on 7 February 1844. This was originally a terminus, but in 1860 the line was continued to Admiralty Pier. Thereafter the SER concentrated most of its resources into developing Folkestone Harbour, which became its principal base for cross-channel ferries.[13] The company had complete control of Folkestone whereas at Dover it had to negotiate with both the Admiralty and the local town council, and the rail route from Boulogne to Paris was better developed than that from Calais.

In 1848 the SER served two steam ships a day between Folkestone and Boulogne, one a day between Dover and Calais, and one between Dover and Ostend.[14]

During 1843, before the main line was complete, the SER and the L&CR became anxious about the charges imposed by the L&GR for the use of the terminus at London Bridge and its approaches. Parliament had relaxed restrictions on new railways into London and so SER sought authority to construct a branch from Corbett's Lane to a new temporary passenger terminus and goods station at Bricklayers Arms railway station, for use by both railways, removing the need to use the Greenwich Railway.[15] This opened 1 May 1844.[5] According to Charles Vignoles, 'the making of Bricklayers Arms station was a matter of compulsion in driving the Greenwich people to reasonable terms'.[16] Plans to extend from Bricklayers Arms to a new SER terminus at Hungerford Bridge, nearer the centre of London, were rejected by Parliament.[17] Similarly, a revised proposal to extend the line to Waterloo Road in 1846 was rejected by a committee of Parliament.[18]

The L&GR was nearly bankrupt in 1844 and the SER leased its line from 1 January 1845. It became the Greenwich branch of that railway.[19] Thereafter further developments were at London Bridge, and following a shunting accident during August 1850 which caused the collapse of a large part of the station roof,[20] the SER closed Bricklayers Arms terminus to passenger traffic in 1852 converting it into a goods facility.

In 1844 the SER took over the bankrupt Canterbury and Whitstable Railway, which had opened in 1830. This continued to be worked as an isolated line until the SER reached Canterbury from Ashford in 1846, with its line to Ramsgate.[21]

The first branch built by the SER was the Medway Valley Line on 24 September 1844, from Paddock Wood to Maidstone. This was continued to Strood railway station on 18 June 1856.[22]

Leasing the London and Greenwich Railway from 1 January 1845 gave the company control of its main line into London and provided a branch line to Greenwich. Further eastward extension was not possible due to opposition from the Greenwich Hospital, but it was eventually opened in 1878 when the line joined the North Kent Line at Charlton.

A secondary main line from Tonbridge to the outskirts of Tunbridge Wells opened 20 September 1845. It was extended to Tunbridge Wells Central on 25 November 1846.[23] By 1 September 1851 the line had reached Robertsbridge and was extended to Battle, Bopeep Junction and Hastings on 1 February 1852. By this time Hastings had already been reached by the SER in a roundabout route from Ashford, which opened 13 February 1851.[24] From this line was a short branch to Rye Harbour.

During 1846 the SER opened another secondary main line from Ashford to Ramsgate with a branch from there to Margate on 1 December 1846.[23] A further branch from this line from Minster to Deal was opened 7 July 1847.

As the SER was prevented from extending its Greenwich line, it opened a secondary main line from Lewisham to Gravesend and then to Strood on the banks of the Medway on 30 July 1849.[24] The second half between Gravesend and Strood had been built as the Gravesend and Rochester canal and a single track railway had been added to form the Gravesend and Rochester Railway. The SER offered to buy the canal and railway in 1845, filled in the canal through the Higham to Strood tunnel and doubled the track.[25] The first section (built by the SER) connected Woolwich and Dartford to the railway network.

In 1852 a freight branch was constructed from this line at Charlton to the Thames at Angerstein's Wharf, used for landing coal.[26] A line opened on 18 June 1856 up the Medway valley to Maidstone West.

In 1846 the SER supported the formation of the Reading, Guildford and Reigate Railway, a scheme to build a line connecting the London to Brighton main line at Redhill with the Great Western Railway (GWR) main line at Reading,[29] and agreed to operate its services. The new line was completed 4 July 1849, and in 1852 was absorbed by SER.[30] Both the LB&SCR and London and South Western Railway (L&SWR) regarded this line as a significant incursion into their areas of operation. Likewise the acquisition of a line so remote from its main area of operation, and of doubtful profitability, caused heated discussion and the resignation of several directors, who felt that the company should rather secure its territory and develop services in Kent, as the LB&SCR was doing in Sussex.[31] It would also ultimately bring about Macgregor's downfall.[32] Nevertheless, in 1858 the GWR, L&SWR, and SER made a three-year agreement to share traffic and provide a connecting line between their stations at Reading.[33] The line now (2015) forms part of the North Downs Line.

During the first years, relations between the SER, L&CR and L&BR were cordial, with the companies pooling locomotives and forming a joint locomotive committee.[34] However, all three considered they were disadvantaged by this arrangement and in 1845 gave notice of withdrawal. The merger of the L&BR and L&CR to form the LB&SCR in July 1846 created a powerful rival to the SER in areas of east Sussex and east Surrey not yet connected to the railway. Relations between the two companies were bad from the outset, especially at those sites where they shared facilities, such as the approaches to London Bridge, East Croydon, and Redhill. Also the SER had long wanted to build a line to Brighton,[35] and the LB&SCR had inherited plans for a line into mid-Kent from the L&CR,[36] and from Bulverhythe (St Leonards) to Ashford via Hastings from the L&BR. Matters were further complicated in 1846 when the SER was empowered to build a line from its existing branch at Tunbridge Wells to Hastings.[37]

Unsuccessful discussions took place regarding a merger of the two companies, but eventually an agreement on 10 July 1848 (ratified in Parliament in 1849) abolished tolls for using each other's lines and prevented further eastward expansion by the LB&SCR beyond Hastings and westward further expansion by the SER.[38] Under this agreement the LB&SCR, would share the line from Bulverhythe to Hastings and transfer to the SER its rights to build a line to Ashford but at the same time it retained the right to use the Bricklayers Arms branch and construct its own 15-acre (61,000 m²) goods depot on the site for a rent of one shilling (£0.05) per year.[39]

The 1848/9 agreement did not prevent further squabbling between the two companies, notably with the opening of the railway from Ashford to Hastings in 1851. The LB&SCR had originally sought to build it and then had attempted to delay its completion by the SER. In retaliation, the SER attempted to deny LB&SCR access to its station at Hastings. The matter was resolved in court in favour of the LB&SCR, but victory was short-lived as the following year the SER opened its lines from Tunbridge Wells, reducing the distance by rail to Hastings from London.[40]

Macgregor's greatest strategic mistake was his failure to address the concerns of the proposers of the East Kent Railway, which ultimately led to the creation of an important rival in northern Kent and also for the Continental rail traffic.

Between 1844 and 1858, the SER had a monopoly of rail transport in Kent, but served the north of the county poorly. The SER line from Strood into London had opened in 1849. A plan to continue this line as far as Chilham where it would join the Ashford to Canterbury Line, was rejected by Parliament in 1847 due to financial considerations and never resurrected.[41] One group of SER directors were anxious to 'close the capital account' and build no more lines,[42] even though this might leave the field open to rival projects, as would later prove to be the case. As a result, there was no planned service to the north Kent towns to the east of the River Medway. Likewise SER routes to Margate, Deal, and Canterbury were circuitous and other towns had no railway at all. As a result of the railway's unwillingness to act, plans for an independent line from the SER station at Strood to Faversham and Canterbury were made following a public meeting at Rochester in 1850.[43]

The East Kent Railway (EKR) from Strood to Canterbury, proposed in 1850 achieved parliamentary approval in 1853, and also for an extension to Dover in 1855, but it failed to secure running powers over the SER line into London: instead the SER reluctantly agreed to handle London traffic from the line.[46] Many SER directors were convinced the line would never be built, or would go bankrupt, and so took no interest in the scheme or in suggestions that the line should amalgamate with their railway.[47] They were proved wrong.

In 1856 the EKR again unsuccessfully sought running powers over the SER into London, and then obtained powers to build its own route via St Mary Cray railway station and Bromley South railway station. The EKR secured running powers over the LB&SCR lines into Pimlico and, after 1860, to Victoria Station.[48] The EKR became the London Chatham and Dover Railway (LCDR) in 1859 and completed its rival route to Dover on 22 July 1861. By July 1863 the LCDR had its own independent route to Victoria, and in 1864 its own terminus on the edge of the City of London at Ludgate Hill.[49] For 36 years it would be an important competitor of the SER both for Continental and also local traffic in Kent.

A further serious strategic mistake was the refusal of the SER to accept the terms of the contract for the cross-channel carriage of mails in 1862, as this stipulated the use of Dover rather than Folkestone.[50] This enabled the London Chatham and Dover Railway which had only reached Dover in 1861 to secure the contract and the following year would give it leverage when it came to negotiating the Continental Traffic Agreement.

A new and protracted dispute with the LB&SCR took place between 1855 and 1862 over the Caterham branch line, which was built by an independent company in SER territory but connected to the railway network at the former LB&SCR station at Purley. The SER refused to allow the line to be leased to the LB&SCR, which in turn refused to re-open its station, delayed opening of the line for a year, and made the Caterham company bankrupt. The SER took over the line in 1859, but the LB&SCR made life difficult for passengers to London.

The SER objected to the LB&SCR agreement with the East Kent Railway (later the London Chatham and Dover Railway) to provide access over its lines to its Pimlico station and later the jointly owned Victoria station (see below), and also for handling that company's freight traffic at 'Willow Walk', (a part of the Bricklayers Arms goods facility). Further difficulties between occurred at East Croydon railway station in 1862. With completion of the LB&SCR line to Victoria station, extra platforms were needed to accommodate the service. The platforms were treated by the LB&SCR as a separate station, named "New Croydon", with its own ticket office, and ran exclusively LB&SCR services. This enabled the railway to offer cheaper fares from New Croydon to London than the SER which only had use of East Croydon station.[51] The SER responded by gaining Parliamentary approval to build its own line from New Beckenham to a new station at Croydon (Addiscombe Road), which opened 1 April 1864.

Relations with the LB&SCR reached a low point in 1863, when the general manager and secretary had to report the history of relations between the companies since the agreement of 1848–9.[52] This set out the history although from the SER perspective.

A branch from Lewisham to Beckenham opened in 1857, becoming the temporary terminus of the East Kent Railway. Following the dispute with the LB&SCR over New Croydon (see below) an extension of this line to Addiscombe (Croydon) was opened in 1864.[53]

The SER and the LCDR agreed to pool Continental traffic receipts between Hastings and Margate, together with local receipts to Dover and Folkestone. It then re-allocated them to a formula which gave the SER two-thirds of the receipts in 1863, gradually reducing to one half in 1872.[54] The agreement appeared to unduly favour the LCDR, particularly after 1870. It did not prevent competition as the railways could claim additional funds from the pool if they carried more than their proportion of customers. Both companies sought to get round the agreement - the LCDR by establishing a Continental service from Queenborough on the Isle of Sheppey, which was outside the scope of the agreement. Similarly, the SER built a local station at Shorncliffe on the edge of Folkestone, which it claimed was not part of Folkestone, and from which it charged lower fares.[55]

Following establishment of a LCDR service from Queenborough to Flushing, Netherlands in 1876, the SER was allowed to build the Hundred of Hoo Railway from its line near Gravesend to a new port on the across the Medway from Queenborough, called Port Victoria. The line opened in September 1882.

In 1860 the LCDR had a more direct route to Dover than the SER, and both the company's rivals had access to a London terminus in the prosperous West End of London while the SER only had its terminal on the south side of the river Thames at London Bridge.

Charing Cross before it was built over with offices with the later SR initials retained.

The SER converted part of London Bridge to through platforms and extended to near Waterloo, over Hungerford Bridge to a station at Charing Cross which opened on 11 January 1864.[56] When the LCDR built a line to Ludgate Hill railway station in the City of London in 1865, the SER built a new bridge over the Thames and a city terminus at Cannon Street railway station, which opened 1 September 1866.[57] These extensions were difficult to operate and were congested at peak times.

On 16 August 1866 the SER agreed with the London and North Western Railway to build a joint line between Euston railway station and Charing Cross, with interchange of traffic,[58] but the scheme was abandoned as a result of the 1867 financial crisis.

The SER therefore constructed the direct line via Sevenoaks to Tonbridge. It involved crossing the North Downs by summits and long tunnels at Knockholt and Sevenoaks. The latter was the longest tunnel in southern England at 3,451 yards (3,156 m). This cut-off line, 24 miles (39 km) long, reached Chislehurst on 1 July 1865, but took three more years to reach Orpington and Sevenoaks (2 March 1868). The new main line opened on 1 May 1868 when the line reached Tonbridge.[57]

Construction of the main line provided the opportunity to build an improved route to Dartford from Hither Green via Sidcup. This opened 1 September 1866.

In 1865 the SER joined a consortium of six railways to form the East London Railway, which used the existing Thames Tunnel to connect Wapping on the north bank of the Thames with Rotherhithe on the south. The other partners were: the Great Eastern Railway (GER), the London, Brighton and South Coast Railway (LB&SCR), the London, Chatham and Dover Railway (LCDR), the Metropolitan Railway, and the District Railway. Over the next four years it was converted to railway use and connected with existing lines.[59]

The line was principally used for freight across London but the SER introduced a service between Addiscombe and Liverpool Street from April 1880 until March 1884. From March to September 1884 the service ran from Addiscombe to St Mary's Whitechapel Road.

One result of improved relations between the SER and the LB&SCR during the 1870s was that the two collaborated in construction of a line between South Croydon on the main Brighton line and Oxted. The completion of the Orpington cut-off in 1866 reduced services to and from the growing town of Croydon. The LB&SCR had supported a plan to build the Surrey and Sussex Junction Railway along this route in 1865, but its involvement had been opposed by the SER as being contrary to their agreement, and the scheme was abandoned during the 1867 financial crisis. However, following a revised agreement, the scheme was revived as a joint venture. Beyond Oxted the LB&SCR linked with its lines to East Grinstead and Tunbridge Wells, while the SER joined its original main line to Tonbridge Tunbridge Wells and Hastings. Authority for construction of these lines was granted in 1878 and they opened in 1884.

As a part of the same scheme, the SER at last began to implement plans for the a line from Dunton Green on its new main line to Oxted via Westerham, the first phase of which opened on 7 July 1881. Authorisation for line was first obtained in 1864, but no progress had been made by 1876, when local inhabitants sponsored a bill their own bill, forcing the hand of the SER.[66] In the event only the first phase (from Dunton Green to Westerham) was built, leaving a Branch line rather than a through route. The remaining four miles (6 km) to the new Oxted Line (then still under construction) were never completed due to opposition in the House of Commons and the difficult terrain between Westerham and Oxted.[67]

During the 1880s and 1890s the SER was accused of only caring about Continental travellers and of neglecting the interests of its other customers. A series of letters to The Times in London in 1883 demonstrated how unpopular the railway had become with its regular commuters.[68] Ernest Foxwell, also writing in 1883, stated 'The great blots on the South Eastern are its unpunctuality, its fares, its third class carriages, and the way in which local interests are sacrificed to Continental traffic.'[69] Hamilton Ellis later described both the SER and the LCDR at this time as 'bywords of poverty stricken inefficiency and dirtiness'.[70] In spite of these criticisms the shareholders stuck with their chairman, until they eventually realised that their own interests were suffering as well. A scathing article in The Investors Review for June 1894 demonstrated how poorly Watkin's railways had performed financially compared to others, and referred to the SER's 'bitter hatred towards all but first-class travellers, [and] their determined cultivation of the art of running empty coaches'. The article finished,

the Company is now almost too weak to turn round and adopt a wise policy. It might become bankrupt in the process ; so the best thing to do is to leave it severely alone. Just as none travel by it who can find another route, so none should touch its common stocks who are free to do otherwise.[71]

Watkin retired shortly afterwards.

Some of the complaints of unpunctuality of the SER may have been exaggerated, or were at least soon remedied after Watkin's departure, since a statistical survey of the company's services conducted in 1895 by William Acworth found that, with the exception of the heavily congested and difficult to operate lines between London Bridge and Cannon Street and Charing Cross, the company did not perform significantly worse than others in London in terms of timekeeping.[72]

During the 1870s and the 1880s the railway attempted to exploit the potential of the East Kent coast as both holiday destinations and potential new channel ports. Thus branches were built from Sandling near Folkestone to Hythe and Sandgate, (opened 9 October 1874); from Dover to Deal and Sandwich (jointly with the LCDR, which opened 15 June 1881); from Appledore to Dungeness (1 April 1883) and New Romney (19 June 1884). (In 1897 the SER obtained powers to build a branch line from Crowhurst railway station to its own station at Bexhill-on-sea in opposition to the existing LB&SCR service to the town.) However this line was not completed until 1902.[73]

On 4 July 1887 the railway opened the Elham Valley Line from Canterbury West to Shorncliffe. However, there was by then already an LCDR line from Canterbury to Dover and so the new line did not attract much traffic. Likewise on 1 October 1892 the Hawkhurst Branch from Paddock Wood to Hope Mill was opened and extended to Hawkhurst on 4 September 1893.

Similarly the company also obtained Parliamentary Powers to build a line from Appledore to Maidstone via Headcorn and the Loose Valley.[74]

Probably the most wasteful competitive venture by the SER was a second bridge over the river Medway between Strood leading to a branch to Rochester (opened July 1891) and to Chatham. The branch line only had a twenty-year life-span as the stations were less conveniently sited than the LCDR alternatives. The LCDR main line was however re-aligned after 1911 to use the newer bridge.[75]

Unlike the neighbouring LB&SCR, the SER failed to capitalise on the rapidly growing population of the South London suburbs during the 1870s and 1880s, and to develop effective suburban services. In particular, the area between the North Kent Line the Dartford Loop Line became well populated at this time, but the SER was reluctant to build a proposed Bexleyheath Line, including stations at Blackheath, Eltham, Bexleyheath and Slade Green, in spite of public pressure in the 1880s. This line was eventually built as a private concern in 1895, and it was only after the original investors had gone bankrupt and Watkin had retired that the SER eventually agreed to incorporate it into its system.

As mentioned above, the line from London Bridge to Charing Cross and Cannon Street was particularly congested and difficult to operate. During the early 1890s the SER was actively considering extending the Bricklayers Arms branch into Charing Cross and Cannon Street as a means of relieving this congestion, but deferred making any decision to do so and ultimately the idea was dropped following the operating agreement with the LCDR in 1899, which provided the new 'joint railway' with two further pathways into London.

One of the last branch lines to be incorporated into the SER was between Purley and Tattenham Corner railway station. The line as far as Chipstead and Kingswood were built by the Chipstead Valley Railway from 1893 and opened in 1897. The extension to Tattenham Corner was built by the Epsom Downs Extension Railway from 1894. Both companies were acquired by the South Eastern Railway.,[76] but the line to Tattenham Corner was not completed until 1901, after the working agreement with the LCDR. This line was in the territory of the LB&SCR but provided the railway with access to a proportion of the lucrative Epsom Downs Racecourse traffic.

Prior to 1862 the company carried international postal traffic. However, in 1862 they refused to renew the contract as it stipulated the Dover-Calais rather than the SER's preferred Folkestone-Boulogne route. As a result, the contract went to the LCDR.[78]

It was not until after the formation of the SECR Management Committee in 1899 that the company began to take the development of its freight traffic seriously, with the ordering of a powerful new freight SECR C class.[79] Prior to that most freight on the system had either been products imported through the Channel ports, or else locally developed freight, such as farm produce travelling to London. The principal freight depot on the system was at Bricklayers Arms.

The cement industry based around Swanscombe and the Medway Towns provided some minerals traffic, but again it was only after the foundation of Blue Circle Industries in 1900 that this was developed. Similarly, the Kent coalfield was not discovered until 1890 and only developed in the early twentieth century.

As mentioned above, the SER was accused during the 1880s of concentrating on its Boat trains and Continental passenger traffic at the expense of its local services in Kent and the London suburbs.

One area where the SER did fail compared with the LB&SCR and the L&SWR was in developing effective services to the rapidly growing suburbs of south east London. This was probably due to an unwillingness to generate even more traffic through the very restricted entry pathway into London between Deptford and London Bridge. The SER did however have the advantage of taking commuters far closer to the centres of business and commerce at Charing Cross and Cannon Street, whereas the LB&SCR and LS&WR deposited them south of the river Thames at London Bridge and Waterloo respectively.

The SER served an area with a long coastline within easy travelling distance of London. During the 1860s the railway was an important factor in the development of holiday destinations such as Margate and Ramsgate in Kent and St Leonards-on-Sea and Hastings in East Sussex.

In May 1844 the SER organised the first of seven rail and ferry excursions that year from London to Boulogne which together carried more than 2,000 people.[80]

By the 1870s, the South Eastern Railway was running Hop Pickers' Specials to transport large numbers of working-class Londoners to towns and villages in Kent and East Sussex for the season.

Electric telegraph was installed throughout the SER by 1848.[14] These were sold to the General Post Office for £200,000 in 1870[81] (equivalent to £20,360,000 in 2021).[82]

The SER did not have a good safety record with a large number of both major and minor accidents throughout its independent existence.

One of the most notable accidents occurred on 9 June 1865, when the boat train from Folkestone ran onto a partly dismantled bridge near Staplehurst. The locomotive and tender ran across the timber baulks to reach the far side, but the carriages were derailed and fell into the River Beult. The Staplehurst rail crash killed ten passengers and Charles Dickens narrowly avoided severe injury, or even death. He was travelling with Nelly Ternan and her mother at the front of the train in a first-class carriage, which escaped complete derailment when the locomotive and tender left the track as a result of repairs to the line. Timber baulks under the track were being replaced but the foreman mis-read the timetable, and two lengths of rail were missing on the viaduct. As the lead vehicles left the line, the impact on the remaining beams caused the cast iron girders below to fracture, and most of the following vehicles left the viaduct and ended up in the River Beult some 15 feet (4.6 m) below. The foreman was indicted and convicted of manslaughter, and served 6 months hard labour for his crime.[83]

Other significant accidents involving multiple fatalities were as follows:

• 11 December 1844 the boiler explosion of locomotive No. 78 Forrester caused a bridge collapse near Bricklayers Arms, Surrey and killed two staff.[84][85]
• 21 August 1854 a collision at East Croydon railway station killed three passengers. This accident also involved the LB&SCR signalman and was later judged to be partly the result of signalling error and poor communication, as well as the SER driver.
• 12 September 1855 - a collision between two trains near Reading station killed five.[86]
• 28 June 1857 - the Lewisham rail crash killed 11 people. An express train ran into the rear of a stationary train due to driver error.[87]
• 30 June 1858 - a derailment near Chilham railway station due to a mechanical failure killed three persons.[88]
• 16 December 1864 - a collision near Blackheath. A ballast train had divided in a tunnel, and an express passenger train was allowed to enter due to an error by a signalman. Five platelayers were killed.[83]
• January 1877 - a landslip at the eastern end of Martello Tunnel brought down some 60,000 cubic yards (46,000 m³) of chalk, killing three men. The line was closed for two months.[89]
• 7 June 1884 - A double-headed freight train ran into the rear of another freight train at Tub's Hill station, Sevenoaks. Both crew of the first train were killed. the Hildenborough signalman was charged with causing their deaths. The trains were being worked under the time interval system.[90]
• 9 October 1894 - a collision near Chartham due to an error by a crossing keeper killed seven.[91]
• 21 March 1898 – Collision at St Johns railway station due to incorrect use of signalling equipment, three persons were killed.[92]

The SER owned fifteen locomotives and had a further eleven on order at the formation of the 'London & Croydon and South Eastern Railways Joint Committee' in 1842.[94] Ten locomotives were built by this committee, and a further 45 were either built or ordered by the enlarged Brighton, Croydon and Dover Joint Committee. The SER received 67 of these existing locomotives at the dissolution of the latter committee in 1846.[95] Having decided to withdraw from the locomotive pool, the SER appointed James Cudworth as Locomotive Superintendent on 22 May 1845. Four locomotives were acquired from the 'Gravesend and Rochester Railway in 1847,[25] seven from the L&GR in 1848, but the only original locomotive to work the Canterbury and Whitstable Railway was not added to stock.[96] Between 1846 and 1898 the SER built or purchased 775 locomotives.[97] Of these, 459 were running on 31 December 1898 when they were handed over to the SE&CR.[98]

Under Cudworth the railway was the largest British user of the experimental and ultimately unsuccessful Crampton locomotive type with twenty examples built between 1847 and 1851.[99] He also patented a double-firebox which enabled locomotives to burn cheaper coal without smoke, but were considerably more expensive to build and maintain.[100] Cudworth also provided several sound locomotive types for the railway, but resigned in 1876 after Sir Edward Watkin ordered 20 express locomotives against Cudworth's wishes, which subsequently proved to have been unsuccessful.[101]

After a brief interregnum James Stirling was appointed Chief Mechanical Engineer on 28 March 1878. He modernised the locomotive stock and was responsible for the building or acquisition of 401 locomotives.[102] Stirling designed some good quality locomotive classes, notably his R 0-6-0, and Q 0-4-4 tank classes, and his O 0-6-0 and F 4-4-0 tender classes. However his determination to maintain standardisation meant that the introduction of larger locomotives was delayed too long and the SER locomotive fleet was underpowered by 1899.[103] As a result, future SE&CR locomotive practice was based on developing LCDR rather than SER designs.
