Service on the Metropolitan Rapid Transit (MRT) Yellow Line remained suspended since Thursday morning after some parts fell from the track in an accident that reportedly damaged three vehicles, with no injuries reported.

Eastern Bangkok Monorail Co Ltd, which operates the driverless train, said parts of the conductor rail had dropped from the track between the Kalantan and Si Udom stations. The accident damaged two cars and one motorcycle but no injuries were reported, it added.

Social media channels of the Yellow Line only announced that the service had to be suspended at all stations as the company is trying to fix the problems.

The suspension began before 9am as commuters were using the line to get to work during rush hour. A train was ordered to stop between the stations, and staff were seen helping passengers to evacuate from the cars by walking along the track.

Some passengers took photos and videos during the unusual experience of walking along the track.

Images of some fallen parts were posted on social media.

The Yellow Line monorail runs between Lat Phrao and Samrong. The service started in July last year.

Thursday’s incident was the second mishap on the monorail system, from which a wheel fell on Jan 2 and struck a taxi on the road below.

The January incident came just a week after a section of conductor rail on the Pink Line monorail broke free and fell onto a street, damaging several parked cars parked along Tiwanon Road in Nonthaburi.
