SINGAPORE - All electrical power cables along the Tuas West Extension will be replaced following a massive three-line breakdown which left more than 6,700 passengers stuck on stranded trains for up to three hours on Oct 14.

The fault should have been isolated by circuit breakers in the vicinity, but one failed to trip as designed due to a faulty trip coil. These earlier faults did not lead to any widespread service disruption because circuit breakers meant to isolate them worked, the LTA said.
