Seven passengers were stranded in for more than an hour in the Ngong Ping cable car on Lantau Island, the second glitch in three days after a system failure on New Year's Day. Last night's disruption occurred during the last ride of the day from Ngong Ping to Tung Chung. Seven passengers in three cars were stranded at 6.19pm, the service was restored at 7.38pm and passengers arrived at the cable car terminal at 8pm. A spokesman said it was due to an electrical malfunction. The glitch on New Year's Day disrupted the cable car service for nearly 90 minutes. Nearly 2,000 people were left waiting in line, with some complaining they had to queue up for almost two hours. 'The Skyrail-ITM cable car really made a bad impression at the beginning of 2007 by having these technical problems,' said legislator Fred Li Wah-ming, a member of the Legislative Council's economic services panel. He said the root of the problem might lie in the management. 'I am questioning their ability. Cable cars have no high-technology, why are there so many technical problems coming up?' Mr Li said. 'The government has to give warnings this time. The transport bureau, the economic bureau, and the MTR Corporation should seriously discuss the matter. Investigations should be done and a report has to be handed to the Legislative Council.' If investigations found signs of management problems, the government should terminate the contract, Mr Li suggested. The Tourism Commission yesterday was deeply concerned over the New Year Day's disruption. It reminded the MTR Corp and Skyrail-ITM to inform passengers, the media and make public announcements as soon as any malfunction happened. Skyrail-ITM reviewed the New Year's Day disruption and details have been handed to Electrical and Mechanical Services Department. The cable car has suffered several disruptions since it opened on September 18.
