都城嘉慕威曼都城巴士
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.
