Kowloon Motor Bus Fleet Numbering - Age of Air-conditioned Buses

Age of Air-conditioned Buses

Things became more complicated and chaotic when there air-conditioned buses began appearing in the KMB fleet. Since the first production air-conditioned bus for KMB is 11 metres long, it was adopted as the standard length. An A was added in front of that code. For the 12m variety, a 3 was added in front (but the standard one was 3-axle). However, for the shorter ones, though it is marked by an S, it is placed after the manufacturer code. There is also a drift from the purely manufacturer based to make based for the "manufacturer" code for the common manufacturers.
