Hong Kong MTR officials say normal service returning to East Rail line after derailed maintenance train causes travel chaos
- Trains back on track between Tai Po Market and Fo Tan after chaotic nine-hour suspension of services
- Rail operator promises probe into cause of incident, which triggers major travel disruption

MTR officials have said services were returning to a key line connecting Hong Kong with mainland China after the route was paralysed for nine hours by a derailed maintenance train.
A carriage of the northbound train, which was used for overnight repair and maintenance work on the East Rail line, came off the tracks at 3.50am in an unprecedented incident, according to the company.
The MTR Corporation said services were gradually resuming from 2.27pm, ending the lengthy suspension between Tai Po Market and Fo Tan.
The carriage in question was removed from the track, it said.
Bosses at the embattled operator had apologised for the disruption, which caused the closure of University station and travel woes for tens of thousands of commuters.
The corporation’s head of operations engineering, Tony Lee Kar-yun, said the MTR Corp would investigate the circumstances surrounding the incident.
