A cross-border bus operator has threatened to withdraw an offer of new buses unless the Government does more to relieve congestion at a key checkpoint. Shenzhen New Fukong Transport Development Company, which runs the Lok Ma Chau-Huanggang shuttle service, promised to replace the fleet with larger double-door buses last August. It has a fleet of 10 single-deck, single-door buses which carry about 5,000 passengers a day across the border. Each bus is allowed to carry a maximum of 55 people per trip. Bus company spokesman Man For-tai said 10 new buses had been ordered which could carry up to 88 passengers each trip, but the Transport Department had only allowed the company to use six of them and had also imposed a limit of 70 passengers. He said this was because the Immigration Department said it could not handle more travellers. The buses are expected to be ready for service in April or May. 'If the Transport Department will not give an inch on the matter, we will have no choice but to redeploy the new buses to other routes once they start arriving towards the end of this month,' Mr Man said. Thousands of SAR holidaymakers were made to wait for hours for buses at Lok Ma Chau during the Lunar New Year. The Transport Department would not comment on Mr Man's threat, but said the second phase of improvements to the Lok Ma Chau checkpoint would be completed in September 2003.
