Singapore transportation system is a modern, air-conditioned passenger train service with stations all over the island. There are three main lines – the North-South line from Marina Bay to Jurong East, the East-West line from Changi Airport/Pasir Ris to Boon Lay, and the North-East line(NEL) from Harbour Front to Punggol.
The North East line is the longest driverless underground transportation spanning for 20.7kms with 16 stations Harbour Front (south) to Punggol (North east) of Singapore.
I had been for a purchase at Mustafa and on return I took up the NEL from Farrer Park to HF. When I got down in HF, one of the two doors of my train car did not open due to some problem. But to my surprise, The platform screen doors of that particular car also was closed in correspondence with the train door.
I was perplexed and asked the authorities about the system. He briefed me about the NEL and its Signalling System. Following is a short note on the same.
Singapore MRT designed for a fully automated driverless train operation The Platform Screen Doors (PSD) are aesthetically esigned to blend in with the stations’ design. It minimises energy consumption by preventing air-conditioned cool air from escaping into the tunnel, and acts as a safety barrier for assengers standing between the platform and tracks.
The Platform Screen Door are operated by an electrical drive system upon receipt of vital PSD operation controls from the signalling system in the nominal driverless mode. The PSD controller provides status indication on individual PSD to the station management system.
The Singapore MRT are operated in set of six with positive door lock mechanism lea cars. The individual local door control unit is designedving no room for ambiguity in door status. There is a close interaction with signalling from the automatic train control unit to the station management systems which provides crucial platform door opening synchronization with train door operation and coordination with other station operations.
Whenever I travel in the pink lane, I am dumbfounded by the growth of technology.
