1971 Bus Reorganisation

Introduction
The 1971 Bus Reorganisation was conducted on 11th April 1971 and all 130 existing bus routes, operated by 12 different bus operators were rationalised and reorganised. The aim for the Bus Reorganisation was to minimise the possible duplication of bus routes. Besides that, a new fare stage based fare was also introduced.

In the Bus Reorganisation, the bus services were operated by 4 bus companies as a result of the merger. They are the Amalgamated Bus Co. (ABC), Associated Bus Services (ABS) and United Bus Co. (UBC), together with the Singapore Traction Co. (STC), whereby STC had lose its monopolisation to run its bus routes within the city.

However, the STC had suffered great financial losses within the period of 1971 and had to permanently closed its bus operations on 1st December 1971, with the revocation of its omnibus license. Affected bus services operated by the STC were evenly distributed to the remaining 3 existing bus operators, i.e. ABC, ABS & UBC, until the remaining 3 bus companies merged to the Singapore Bus Services (SBS) on 1st November 1973. The distribution of the former bus services operated by STC are highlighted accordingly on the STC section of the "List of Bus Routes" table below.
