Update on number of cracked equipment found on East Rail trains up to noon, 19 Jan
 
The Kowloon-Canton Railway Corporation (KCRC) today continues to conduct non-destructive test (NDT) on the welding of mounting brackets of East Rail trains underframe components. As of noon today, among the 148 major components checked in the past day, cracks were found on 1 upper mounting bracket of main transformer, 2 battery chargers, 2 battery boxes and 1 MA Choke. In addition, cracks were found for the first time at the mounting bracket of 4 main equipment cases. For the 9 non-major components checked, cracks were found on 1 more rectifier case (please refer to attachment for details).
As new cracks continue to be found on the mounting brackets of other components, the examination cannot be completed by 20 January. KCRC requires more time to conduct thorough inspection.
KCRC also maintained close contact with and continuously update the Transport Department on the latest service arrangement after East Rail switched to manual driving under the safety protection of the Automatic Train Protection (ATP) mode.
The Corporation has deployed additional staff to closely monitor the traffic situation, and will inform the government immediately of any service changes. KCRC also appeals to the public to pay close attention to the announcement made by radio and television, and to plan their journeys early according to their own travel schedules.
For further enquiries, please call the Hotline at 2929 3399.
