LTA Awards Contracts C1320 and C1321

Platform Screen DoorLand Transport of Authority (LTA) of Singaprore has awarded two contracts for the installation Of Half Height Platform Screen Doors (HHPSD) and Associated Works at MRT Stations of North-South and East-West Lines.

What are Platform Screen Doors?
Platform Screen Doors (PSD) are barriers that are installed to prevent public from entering the rail track. PSDs are normally transparent and separate rail tracks from platform. Train doors and PSDs are synchronized to open simultaneously after the train has come to a halt. As such, PSDs help in reducing the risk of accidents by preventing people from falling or jumping on to the tracks. PSDs reduce air-conditioning and ventilation costs by isolating the platforms from the track and tunnels. It also improves the passenger comfort by keeping the platform quiet and clean.

What are Half-Height Platform Screen Doors?
The Half Height Platform Screen Doors are about 1.5 metres high and are installed along the edge of the station platform to create a barrier separating the trackside and the platform. While Full-height Platform Screen Doors serve many purposes as discussed above, Half-height Platform Screen Doors are installed solely to improve safety.

All the underground MRT stations in Singapore are already fitted with platform screen doors while the elevated stations do not have such a barrier. As part of the Land Transport Master Plan, LTA has decided to install half-height platform screen doors to enhance the safety of the rail system. In one of my articles, MRT Train Service Disruption at CCK: Update, I have discussed about the safety at elevated MRT stations.

Contract C1320
Contract C1320 has been awarded to Singapore Technologies Electronics Limited. The contract is worth approximately $112.3 million and includes the design, manufacturing, supply, installation, testing and commissioning of the Half Height Platform Screen Doors and its associated works at the existing 36 elevated North-South and East-West Line MRT stations which currently do not have platform screen doors.

Contract C1321
Contract C1321 has been awarded to Westinghouse Brake and Signal Holdings Limited. The contract is worth approximately $13.9 million and includes the signaling interface to ensure that the Half Height Platform Screen Doors are able to synchronize with the train doors.

The installation of the Half Height Platform Screen Doors is expected to commence in the third quarter of 2008 and complete in the fourth quarter of 2009 at three stations, namely Yishun, Jurong East and Pasir Ris. Subsequently, all the remaining 33 stations will have such doors fitted by 2012.


  1. It's high time that these should be installed. There were a couple of incidental deaths when people just fell onto the tracks in front of an oncoming train. But curiously, it's not happening in London, save some of those newer stations despite the trains carrying more people per day.

  2. Hi CK,

    You are right. If I am not wrong, Singapore was the first one to implement Platform Screen Doors for the underground stations. This will help to enhance the safety of passengers, considering the huge crowds in Singapore MRT nowadays.

  3. I’m amazed, I must say. Rarely do I encounter a blog that’s equally educative and amusing, and without a doubt, you have hit the nail on the head. The issue is something which not enough folks are speaking intelligently about. Now i'm very happy I came across this during my hunt for something concerning this.sbobet
