CAB

CAB is the three-letter station code assigned to Causeway Bay station on the MTR (Mass Transit Railway) network in Hong Kong. Like all MTR stations, Causeway Bay carries a unique alphabetic designator used in scheduling systems, signage, and operational communications. The code appears on departure boards, journey planners, and in the railway's internal documentation.

Causeway Bay station itself sits on the Island Line, one of the original routes opened in 1985. The station serves the commercial district of the same name and handles significant daily passenger volumes typical of central Hong Kong. The CAB code allows dispatchers, station staff, and automated systems to reference the location unambiguously without spelling out the full station name in real-time operations.

Station codes in the MTR system follow a straightforward pattern: each station receives a two-letter line identifier followed by a number, or alternatively a three-letter code for reference purposes. CAB represents the latter convention, making it easy to spot in printed timetables, electronic displays, and inter-station communications. Other Hong Kong stations use similar abbreviated codes; the system mirrors practice on railways and transit systems worldwide.

In practice, staff and regular commuters become familiar with these codes through repeated exposure. Signal control rooms, maintenance depots, and revenue systems all reference stations by these identifiers. For anyone working in MTR operations, planning, or customer information services, knowing the station codes is fundamental to daily work, particularly during disruptions when trains must be rerouted or delayed.
