Citybus Route 13

Route 13 service was started by China Motor Bus (CMB) on 16 April 1974, when the first bus lane in Hong Kong, the one along westbound Caine Road, came into operation. The fare at that time was 50 cents, without child fare concession or section fare arrangements. At that time, the main bus fleet on the line was Guy Arab Mk V (LX class). After CMB converted routes 260, 261 and 262 into full air-conditioned services in 1991, the MCW Metrobus coaches used on these routes were transferred to route 13.

The route was handed over to the current operator NWFB on 1 September 1998, when the franchise for CMB to operate bus services ended. On 13 September 1998 route 13 became a full air-conditioned service. Later NWFB introduced Dennis Trident 10.3m buses (33XX) on the route. After the Star Ferry Pier moved from Edinburgh Place Ferry Pier to the new Central Piers, the Central terminus of the route did not move to the new terminus there; it stayed where it was, only with a change of the name to Central (City Hall).

The route and the location of the termini for route has never been permanently changed since its inauguration until 2012, making it the bus service in Hong Kong with the route sustained for the longest period of time.[1][2]

As a result of Citybus Route 12M reduced service to weekday morning peak only, the route was extended to Admiralty (Tamar Street) effective 14 August 2022.
