Citybus has been put under 24-hour scrutiny by the Transport Department in the wake of the high number of crashes involving its vehicles. A taskforce formed by transport officials and engineers will study 10 accidents in the company's record to analyse its staffing, scheduling and maintenance practices. The taskforce will examine staff deployment and bus scheduling, and will stay overnight in the company's depots to look at its maintenance and inspection procedures. 'All aspects of Citybus' operation will be looked into - ranging from the usage of its buses to any parts that have been changed,' said a transport spokesman. The taskforce was formed to improve services of franchised bus companies after a major Citybus accident on a Wan Chai flyover on January 30 that killed three people. It decided to increase controls on Citybus after 12 accidents in the past three days, causing injuries to four people, with two occurring yesterday. A Citybus driver lost control of a double-decker in Mongkok shortly after 7 am and mowed down a 12-metre railing on Boundary Street. At about 4.30 pm, another Citybus collided with a China Motor Bus outside Hong Kong Regal Hotel in Causeway Bay. Nobody was hurt in yesterday's accidents. Citybus director Lyndon Rees attributed the spate of accidents to 'bad luck' and congested roads, and pledged to improve driver training. The drivers also said a strongly worded notice from management - threatening immediate dismissals for any mistakes - had put them under more pressure. The Hong Kong and Kowloon Trades Union Council yesterday met transport officials to voice concerns that the drivers were being made the scapegoats. Spokesman Chung Chung-fai said Citybus drivers had always been overworked due to ineffective scheduling. 'There may not be rest time between two shifts. The drivers may also need to drive different buses and routes in one day,' he said. The council's chairman, Lee Kwok-keung, said Citybus drivers had kept a low profile and were attached to only one union, while drivers from the other two franchised bus companies were represented by at least two.
