Problem with Emergency Exit on MTR’s Newly Acquired China Made Trains

逃生門設計錯 改動有瑕疵

There have been reports about problems with MTR trains. The newly acquired China made trains, because they have exceeded the “dynamic clearance limit”, emergency doors cannot be fully opened hence the platform cannot be launched. As a result, MTR had to redesign the emergency exit, making the door to drop together with the platform.

A MTR staff said that there are emergency exits at both ends of a train. In any emergency situation, once the emergency exit door is opened and the platform is drop connecting two trains together, passengers can be taken to safety by another train. However, when doing safety tests on the China made trains, it was found out that the emergency exit doors that open to the side touches the tunnel wall, making it impossible to launch the platform.

MTR wanted to put these China made trains into service as quickly as possible, hence they abolished the original design and redesigned the emergency exit door – the door drops together with the platform. However, this change comes with a drawback: the newly designed emergency exit only allows passengers to get off the train and the platform cannot be connected to another train for evacuation, also once the door is opened it cannot be shut again and requires four men to remove it.

After learning its lesson, according to industry insiders, MTR hired experts from the UK to teach the engineers at MTR about “dynamic clearance limit”. However, the same problem appears in the South Island Line.
