Slight delay on North-South Line due to third rail repair works

SINGAPORE - SMRT spokesman Alina Boey said the defective third rail between Ang Mo Kio and Bishan MRT stations was detected Thursday morning by a Linear Variable Differential Transformer (LVDT) placed on a train. The LVDT is a surveillance instrument that monitors track conditions and any anomalies on the third rail, which supplies power to the trains.

Here is the media statement from SMRT on their Facebook page:

Our Linear Variable Differential Transformer (LVDT), a surveillance instrument put in place to monitor track conditions and to pick up on anomalies on the conductor rails, alerted our engineers of a defective third rail between Ang Mo Kio and Bishan MRT stations earlier this morning. SMRT engineers were quickly deployed on site to assess and rectify the fault. Power was shut down at Ang Mo Kio station between 12.05pm and 12.25pm, as SMRT staff went on track to carry out repair works.

Service announcements were made in trains and within the stations to inform commuters to provision for an additional five minutes of travel time between the two stations. Normal service resumed at 12.25pm.

We wish to thank our commuters for their cooperation while we conducted repair works.
