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. 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.
Numbering Until the 1970s, new CMB routes were numbered in consecutive order.
Route 12 was opened in 1955 and
route 14 in 1960, but CMB initially skipped the number 13, citing
the superstitious belief that 13 is an unlucky number as a reason. When CMB planned to operate a new service between Star Ferry Pier and Kotewall Road, the decision to use the number 13 caused controversy within the upper levels of the company. Eventually, the director of CMB,
Ngan Shing-kwan, who was a Christian, announced on a newspaper that he does not believe the unluckiness of the number 13, and decided that the number will be used on the new route. ==Route==
