Train services between Central and Admiralty stations on Tsuen Wan line would be suspended for the rest of Monday, according to MTR Corporation.
Train services between Tsim Sha Tsui and Tsuen Wan stations on Tsuen Wan line would be departed every three and a half minutes.
The incident took place near Central station at around 3 a.m. when a Tsuen Wan-bound train collided with a Central-bound train at the crossover section during a trial run for a new signal system.

The accident involved two trains, one of which was in the direction of Central station and the front of the train was damaged," the official said.
"The other train was in the direction of Tsuen Wan station, and the third and fourth carriages of this train were damaged."
