Construction of the MTR was prompted by a study, released in 1967, commissioned by the
Government of British Hong Kong to find solutions to the increasing road congestion problem caused by the territory's
fast-growing economy.
Construction started soon after the release of the study, and the first line opened in 1979. The MTR was immediately popular with residents of Hong Kong; as a result, subsequent lines have been built to cover more territory. There are continual debates regarding how and where to expand the MTR network.
The MTR has served as a model for some newly built systems, particularly in
China.
The MTRCL is involved in the construction and operation of railway projects in three Mainland China cities, namely Beijing, Shenzhen and Hangzhou. MTRCL also constructs and operates the Macao Light Rapid Transit.

History
Initial proposals

During the 1960s, the government of Hong Kong saw a need to accommodate increasing road traffic as Hong Kong's economy grew rapidly. In 1966, British transport consultants Freeman, Fox, Wilbur Smith & Associates were appointed to study the transport system of Hong Kong. The study was based on the projection of the population of Hong Kong for 1986, estimated at 6,868,000. On 1 September 1967, the consultants submitted the ''Hong Kong Mass Transport Study'' to the government, which recommended the construction of a

was shelved. In this updated scenario, the consultants reduced the scale of the recommended system. The supplementary report stated that the originally suggested four tracks between
Admiralty station and
Mong Kok station should be reduced to two, and only parts of the Island line, Tsuen Wan line, and Kwun Tong line should be constructed for the initial system. The other lines would be placed in the list of extensions.
This report led to the final study in 1970.
In 1970, a revised system with four lines was laid out in the British consultants' new report, ''Hong Kong Mass Transit: Further Studies''. The four lines were to be the Kwun Tong line, Tsuen Wan line, Island line, and

Modified initial system

Several weeks later, in early 1975, the Mass Transit Steering Group was replaced by the Mass Transport Provisional Authority, which held more executive powers. It announced that the Initial System would be reduced to and renamed the "Modified Initial System" (now part of the Kwun Tong and Tsuen Wan lines). Plans for a single contract were abandoned in favour of 25 engineering contracts and 10 electrical and mechanical contracts. On 7 May 1975 the Legislative Council passed legislation setting up the government-owned Mass Transit Railway Corporation (MTRC) to replace the Mass Transport Provisional Authority.
