New East Rail crack
A second cracked rail has been found on the East Rail Line in a month, prompting the MTR Corporation to increase track inspections.
The vertical crack, which extended from the top of the rail to the bottom, lay in the section between Kowloon Tong and Mong Kok East.
It was discovered after a Hung-Hom-bound train ran over it at about 6am yesterday. The train driver felt something was wrong and alerted the control centre. Engineers immediately carried out temporary repairs by securing the rail with steel plates, according to the rail operator.
'The corporation would like to emphasise that the occurrence did not, at any time, affect safe train operations, and train services on the East Rail Line remained normal,' it said.
The operator said the cracked rail was replaced last night after train services ended.
Its spokeswoman could not say whether the affected section had been included in the daily inspection.
'We will investigate the cause with the supplier of the rail,' she said.
On December 28, a hairline fracture was found during a track inspection at Tai Wai. It caused marginal delays to passengers, but had no safety implications.
