SINGAPORE, Nov 6 — Transport operator SMRT confirmed today that maintenance records for the pump system at Bishan station had been falsified between last December and June this year, and spelled out further action it would take against the errant staff.

In a statement announcing the completion of its internal investigation, SMRT said a manager, an engineering supervisor and four other crew members from its Building and Facilities Maintenance group were linked to the falsification of the records.

"Disciplinary proceedings will follow,” SMRT added, without giving further details.

The company is conducting a further inquiry against seven other managerial staff from this Maintenance group with regards to their "supervisory responsibility”.

On October 7, a heavy downpour had led to Bishan MRT station being flooded, and train services on the North-South Line being shut down for over 20 hours.

On October 31, SMRT released the preliminary findings of its internal probe into the incident. The report showed that the crew responsible for the maintenance of the pump system at Bishan MRT Station had signed off and submitted maintenance records for nearly a year, without carrying out the works.
