DispositionAll scrapped

They were officially designated Curved Link 6-ft 6-in Passenger due to the use of a curved link between the fore and back eccentric rods of their Stephenson valve gear and the use of 6-foot-6-inch (1.981 m) diameter wheel centres, which, together with 1+1⁄2-inch (38 mm) thick tyres gave a driving wheel diameter of 6 ft 9 in (2.057 m).[2][3]

They were designed by John Ramsbottom who had 76 built, all without cabs and with pierced driving wheel splashers. Ramsbottom's successor F. W. Webb, built twenty more, all with cabs. The earlier locomotives also gained cabs, and all eventually had the splashers filled in.[4]

All were 'renewed' (replaced) by a like number of LNWR Improved Precedent Class between 1887 and 1894.[5]

Lancashire & Yorkshire Railway

In 1873 ten locomotives of the type were built at Crewe for the Lancashire and Yorkshire Railway (L&YR) and utilised on passenger expresses between Blackpool, Manchester and Yorkshire. They were given the numbers 456–462 and 731–733. Most were fitted with replacement boilers about and other standard L&YR parts 1888. They were then used on Liverpool−Manchester expresses on the new L&YR route. The more powerful Barton Wright 4-4-0s took over on the more demanding sections to Yorkshire though the Ramsbottom engines were considered faster on light loads. Most were withdrawn in the period 1895 to 1897 but Nos. 461, 462 and 731 lasted to 1904, 1912 and 1926 respectively. No. 731 had been used as the Chief Mechanical Engineer's (CME) locomotive since 1886, based at Horwich and attached to a combined bogied tender-saloon vehicle. It passed back to the LNWR when the L&YR amalgamation of 1922 and into the London Midland and Scottish Railway (LMS) in 1923 at the grouping. It was scrapped when the LMS CME department moved to Derby.[6][7]

Preservation

Even though no locomotive from the Newton class was saved for posterity. The Improved Precedent No. 790 Hardwicke (built 1892, LMS No. 5031, withdrawn 1932) currently sitting at National Railway Museum Shildon[8] still display nameplates indicating 1873 as the year of build.
