Гонконг метрополитенінің Tsuen Wan желісі

Hong Kong MTR railway line

The Tsuen Wan line is one of the ten lines of the metro network in Hong Kong's MTR. It is indicated in red on the MTR map. There are 16 stations on the line. The southern terminus is Central station on Hong Kong Island and the northwestern terminus is Tsuen Wan station in the New Territories. A journey on the entire line takes 35 minutes. As a cross harbour route that goes through the heart of Kowloon and densely populated Sham Shui Po and Kwai Chung, the line is very heavily travelled.

The Tsuen Wan line was the second of the three original lines of the MTR network. The initial plan for this line was somewhat different from the current line, especially in the names and the construction characteristics of the New Territories section. The original plan envisioned a terminus in a valley further west of the present Tsuen Wan station. That Tsuen Wan West station is different from the current Tsuen Wan West station on the Tuen Ma line, which is located under land reclaimed at a much later time. The line was supposed to run underground in Tsuen Wan rather than on the ground level, as is currently the case. The approved route was truncated, terminating at Tsuen Wan station. The construction of the Tsuen Wan Extension project was approved in 1975 and commenced soon afterwards. Testing of the new line began on 1 March 1982. The extension was formally opened on 10 May 1982 by Sir Philip Haddon Cave, the acting governor and former chairman of the Mass Transit Railway Provisional Authority. The project was opened seven and a half months ahead of schedule, and cost HK$3.9 billion, under budget compared to the original estimate of HK$4.1 billion. Before the crash site had been cleaned up, all Tsuen Wan line trains terminated at Admiralty and returned to Tsuen Wan Depot instead of Central. Both MTR and Thales will be conducting their separate investigations. The same vendor also provided a similar signalling system in Singapore, which resulted in the Joo Koon rail accident in 2017. In July 2019, the Electrical and Mechanical Services Department (EMSD) published an investigation report into the incident and concluded that a programming error in the signalling system led the ATP system to malfunction, resulting in the collision.
