Electric buses trial on hold again as new failure emerges

Five electric buses purchased by New World First Bus Services Limited (NWFB) and Citybus Limited for trial operation in Hong Kong were found to have faults, including wheel failure and faulty door parts, Sing Tao Daily reports.

A spokesman for the two bus operators said the buses would be taken back to the bus depot for a comprehensive check-up by engineers from BYD Co. Ltd., the manufacturer.

The government earlier allocated a subsidy of HK$180 million for five local franchise bus companies to buy a total of 36 electric buses as part of a trial scheme.

The five BYD buses operated by Citybus and NWFB went into service on Dec. 27 last year, serving routes in the Mid-Levels, Eastern, Wan Chai and Southern districts.

On Jan. 8, or in less than two weeks of operation, it was reported that the anti-trapping rubber on the side of the bus door was overly sensitive and could spring the doors open suddenly.

The problem prompted a suspension of all electric buses for inspection and the service only resumed on Jan. 11.

Last week, a bus driver reported a wheel failure while operating one of the buses in Quarry Bay.

The faulty door parts were traced to software issues, while the wheel failure is still being investigated. 

Another electric bus, manufactured by Shandong Yixing, is said to be on trial operation in Hong Kong, Passion Times reports.
