SINGAPORE: The three-hour disruption of train services on the North East Line (NEL) on Tuesday (Aug 12) was caused by a failure of the power switchboard at the NEL depot’s substation.
Preliminary investigations found that the failure caused a flashover – an unintended electrical discharge – in one of the voltage transformers used to regulate the power supply, said SBS Transit group chief executive Jeffrey Sim in a statement on Aug 12.
