Thirteen thousand jobs will be created by yesterday's Executive Council go-ahead for the $64 billion West Rail project. But residents who fear they will be overrun by traffic were last night considering taking the Government and the Kowloon-Canton Railway Corporation (KCRC) to court. Exco yesterday authorised the construction of the project's first phase, a 30.5km, electrified, double-track railway, from West Kowloon to the heart of Tuen Mun via Yuen Long. It is expected to be completed in 2003. About 45 per cent of the line will be built on viaducts and 40 per cent underground. The remainder will be at ground level. KCRC chairman Yeung Kai-yin said the jobs would include 11,000 construction workers, 1,000 posts at the corporation's West Rail division, and 1,000 jobs for consultants and contractors. The project will produce 40,000 flats from the 10 sites along the West Rail alignment. Mr Yeung said the West Rail would be one of the quietest in the world as it would be built with special measures to cut noise. Secretary for Transport Nicholas Ng Wing-fui said objections against the project and the Government's responses had been passed to Exco before it made its decision. Mr Ng said work on the Tai Lam Tunnel and Kwai Tsing tunnel sections would start soon. The decision to go ahead infuriated residents at Mei Foo Sun Chuen, who have fought against the building of a station on nearby Lai Chi Kok Park. 'It will be very much a repetition of what is presently happening at Kowloon Tong railway station where the narrow streets in surrounding areas are bombarded with an unbelievable amount of traffic every day,' said Gina Tang Mui-kwan, a spokeswoman for the Mei Foo Residents' Concern Committee on West Rail. The group will consider applying for an injunction against the project and campaigning for a new environmental impact study.
