The cost of the $75 billion Western Corridor Railway could be cut by as much as 10 per cent, the Kowloon-Canton Railway Corporation revealed yesterday. Ian McPherson, project director of the West Rail Division of the KCRC, told legislators that they had cut the cost of other projects previously by 10 per cent and could do it again. 'You can design a bridge in different ways and the design would affect the cost,' he said. Secretary for Transport Gordon Siu Kwing-chue said a thorough study was needed before a decision could be made to impose a cap on construction costs. But Selina Chow Liang Shuk-yee, of the Liberal Party, opposed capping because this often resulted in fixed costs contracts being awarded that proved more expensive. At yesterday's Legco question time, Governor Chris Patten said the Government would try to reach a decision on the Western Corridor Railway as soon as it could. He said that this would have to be agreed by the future chief executive of the Special Administrative Region government since the link would be built by the post-1997 government. 'If those decisions have to be arrived at before July 1, 1997, we would of course need to have the enthusiastic agreement of my successor. Otherwise it would make no sort of sense whatsoever.' Democratic Party legislator Zachary Wong Wai-yin asked if the Government had any fresh commitments to ease the traffic congestion in the northwest New Territories as it was unlikely the rail link would be completed by 2001 as originally planned. Mr Patten admitted he could not say when the project would be completed. Meanwhile, a 50-strong coalition comprised of representatives from Yuen Long and Tuen Mun residents to monitor the construction of the railway was established on Wednesday.
