SINGAPORE - Commuters on the Circle Line will not be able to use their mobile devices at Kent Ridge, Haw Par Villa, Pasir Panjang and Labrador Park stations between 7pm and 9pm on Friday (Sept 2) evening.

In a joint announcement made at 6.38pm, the Land Transport Authority and rail operator SMRT said the two-hour shutdown was to eliminate telecommunication signals as a possible cause of a mysterious technical glitch that has bugged the five-year-old line since Monday.

"This temporary suspension of mobile communication services will affect commuters only while they are travelling in the underground tunnels along these four stations and on the stations' underground platforms while waiting for train arrivals," the joint statement read.

 
 

"They will not be able to make mobile phone calls, SMS or access the Internet during the suspension. Commuters who need to make urgent phone calls can approach SMRT staff at the Passenger Service Centre in each station for assistance."

Software experts from French systems supplier Alstom are in town to assist in resolving the signalling glitch that has caused trains to apply emergency braking several times a day for nearly a week now.
