Assoc Prof Jamus Jerome Lim asked the Minister for Transport what are the technical limitations in implementing platform screen doors for the LRT system, similar to those implemented for overground MRT stations in terms of (i) existing trains and (ii) existing platforms respectively.
Reply by Minister for Transport Chee Hong Tat:
1. Platform screen doors require power supply, communications and signal control equipment. As LRT stations are smaller than MRT stations, it is not practical to install all the above equipment as it will reduce the available waiting area for commuters.
2. For commuter safety, all LRT stations have fixed barriers, as well as tactile warning studs along the station platform to warn commuters that they are approaching the edge of the platform. Our operators have also put in place detection systems using artificial intelligence and video analytics to detect track intrusions at LRT stations, and to alert the staff at the operations control centre so they could respond quickly to these incidents.
