Transformers of the type that exploded and caught fire on a West Rail train last week do not need to be replaced, the KCRC's chief executive insisted yesterday. The transformers, also used on East Rail and the Ma On Shan link, are undergoing infrared checks every three days for any temperature abnormalities. New software will also alert drivers to any irregular power flow. Chief executive James Blake said the transformers were in good condition. 'We have so far found that the remaining transformers are behaving in a perfectly normal and sound manner, and we are confident they will not create problems,' he said. 'If there are any signs of problems, we will detect them and will be able to remove passengers from a particular train before a similar event occurs.' The faulty transformer exploded in the morning while the train was passing through Tai Lam Tunnel, forcing 1,100 passengers to flee through a fume-filled passageway. Eleven people were admitted to hospital with smoke inhalation. A seven-member investigation panel, which met on Saturday, confirmed the incident was caused by short circuits. No timetable has been given for the release of a full report.
