SINGAPORE – A second trial involving a temporary switchover to a new signalling system is expected to happen on Thursday (March 30) at around 11pm, after the first trial went smoothly on Tuesday night.

This is part of a continuing trial to switch the network and trains over to a new signalling system.

In a Facebook post on Thursday evening, SMRT said: "We had a successful trial on Tuesday with the switchover for the first new signalling system on the North-South Line (NSL). We'll be carrying out another trial tonight at around 11pm.

"During this time, all trains along the NSL will remain stationary for about 10 minutes as our Operations Control Centre and train captains switch the network over to the new signalling system. In-train and station announcements will be made to keep all commuters informed.

"Commuters may seek assistance from our staff who will be on standby at all North-South Line stations. We thank all commuters for your patience and understanding."

Some changes that were tested out on Tuesday night included the automatic opening and closing of train doors on the new signaling system.

Under the existing system, train captains control the doors manually.Like the first trial, the second trial is expected to involve all trains on the 26-station North South Line (NSL).

On Tuesday, services on the NSL were halted for nearly 10 minute when the trial started at 11.14pm.

SMRT had said that the switchover was successful, and trains on the North South Line was running smoothly on the new signaling system.

It said it continued to monitor the train operations until the end of service on Tuesday, and if there were no issues, it would carry out the next trial on Thursday
