Lightning strikes MRT train; train captain receiving medical attention
[SINGAPORE] An MRT train on the East-West Line was struck by lightning and stalled near Bedok station a little past 4pm on Monday. As a result, journey times between Tanah Merah and Paya Lebar were delayed for at least 10 minutes.
The westbound train heading towards the city stalled as it was approaching Bedok MRT station, Mr Patrick Nathan, SMRT's vice-president of corporate communications, told The Straits Times in a statement.
Passengers were detrained at Bedok station, and the train was withdrawn from service for investigation. After the incident, the train captain, who said he was unwell, received medical attention.
The captain, who was in his 20s, was taken to Changi General Hospital around 4.20pm by a Singapore Civil Defence Force ambulance in a conscious and alert state.
ST understands that the train captain suffered numbness and chest pains.
Mr Nathan said SMRT is "currently investigating this incident as a possible lightning strike".
Trains on surface lines are occasionally struck by lightning, but operator SMRT has said that occupants are protected and are unlikely to be injured in such an event.
Mr Nathan said that each train is protected by a "Faraday Cage", an enclosure formed by conductive material that blocks electric fields and electric currents such as lightning strikes.
"The cage conducts current around the outside of the enclosed space with none passing through the interior. If lightning strikes, the electric current will travel through the outside shell of the train, not through the cabin, and pass through the wheels to the track. The train is grounded to the track," he said.
The National Environment Agency had forecast thundery showers over northern, eastern and central Singapore in the late afternoon earlier in the day, at 2pm.
On May 11, 2016, an SMRT train on the North-South Line was crippled by lightning just before 4pm, disrupting southbound services from Yishun to Yio Chu Kang stations.
An hour before the lightning incident on Monday, an alarm went off at Clementi station on the East-West Line.
When The Straits Times arrived at the station, about a dozen policemen and SMRT employees were seen checking an electrical box near the Emergency Stop Plunger switch.
The police later said it was a false alarm.
