Construction of the Modified Initial System (now part of the Kwun Tong line and Tsuen Wan line) commenced in November 1975. The northern section was completed on 30 September 1979 and was opened on 1 October 1979 by Governor Murray MacLehose. Trains on this route ran from Shek Kip Mei station to Kwun Tong station, initially in a four-car configuration. The first train drivers were trained on the London Underground. The route from Tsim Sha Tsui station to Shek Kip Mei station opened in December 1979. The first line was designed by a consortium of consultants led by Freeman Fox and Partners. On later extensions to the railway the stations were designed under the supervision of Roland Paoletti, the chief architect at MTR.
