A man, who wanted to retrieve his mobile phone, has been arrested for climbing onto the track at Jurong East MRT station on July 6 night.
An oncoming train had to make an emergency stop as a result of the trespassing.
The incident, which occurred at about 10.15pm, caused a slight delay in train services, SMRT said on July 7.
The man was unhurt.
The police said they have arrested a 57-year-old man for criminal trespass.
Investigations are ongoing.
Normal train services resumed at about 10.20pm.
SMRT Trains president Lam Sheau Kai said the train driver on the north-bound train applied the emergency brake when he saw the trespasser on the track.
"The man had climbed over the half-height platform screen door to retrieve his mobile phone from the live track," Lam said.
"Trespassing onto the track is dangerous. This could bring harm to other commuters when emergency brake is applied," he added.
"Please approach our staff for assistance if you need to retrieve your belongings from the tracks."
Trains travelled at a slower speed as an extra safety precaution because of the incident, he also revealed.
