SMRT Corp on Thursday suspended train services between Joo Koon and Tuas Link stations following previous day's collision, which left nearly 29 people injured.

SMRT, the affected line's operator, said in a tweet that free regular and bridging bus services are available between the two stations all day.

On Wednesday, Singapore's mass-rapid rail system suffered a collision when a train operated by SMRT Corp hit another stationary one. The Land Transport Authority said a software glitch was behind the rail collision.

In another tweet, SMRT said train service on the North-South Line (NSL) is running normally.

Commuters on the NSL were told to add 40 minutes of travel time to their journeys.

SMRT operates the two oldest train lines in Singapore, North-South and East-West, as well as the newer Circle line. SBS Transit Ltd. runs the North-East line and the newest Downtown line.

Wednesday's collision was the latest knock on Singapore's reputation for slick infrastructure after the city-state witnessed a commuter chaos earlier this year.

In August, two of Singapore's five mass transit rail lines suffered signaling failures, leaving thousands of disgruntled passengers late for work.
