SINGAPORE — Rail operator SMRT will carry out another trial of its new signalling system on the North South Line (NSL) on Thursday (March 30), after a temporary switchover on Tuesday went smoothly, with trains running on the new system for more than an hour before services ended at night.
Hours before the start of the trial, however, two unrelated breakdowns occurred: A stretch of the NSL — between Bishan and Sembawang — was hit by a signalling fault that persisted for two hours, causing delays of up to 15 minutes. The issue was resolved at about 10.20pm — less than an hour before the trial started. Elsewhere, SMRT’s Bukit Panjang LRT system broke down for an hour.
Nevertheless, there were no hiccups during the temporary switchover — which started at about 11.15pm — to the new system, which involved more than 30 trains and all 26 stations on the NSL. At the start of the test, trains were halted for less than 10 minutes, before services resumed using the new signalling system.
SMRT described the test as successful, and it monitored train operations until the end of service. Some changes tested out included the automatic opening and closing of train doors on the new signalling system. Under the existing system, train captains control the doors manually.
