BUS companies have been waiting more than a year for government guidelines to reduce the danger of landslips to passengers waiting at bus shelters. The three companies - Citybus, Kowloon Motor Bus (KMB) and China Motor Bus (CMB) - said they sent details of all their shelters to the Geotechnical Engineering Office (GEO) more than a year ago. This was in response to an urgent review of slopes near bus stops after a mudslide in June last year which hit a bus terminus in Tsuen Wan, killing one person and injuring five. The tragedy led the GEO to reclassify all slopes near bus stops as ''high-risk'', meaning that if they collapsed many would be hurt. But since submitting the information bus companies have heard very little. The review gained special significance yesterday when a landslide blocked Castle Peak Road at 8 am, just 50 metres from a KMB bus stop. ''We supplied details of all the sites with bus shelters. Since then there has been some correspondence with the GEO and we hear they have been doing slopes surveys. But we have not received any kind of recommendations from them,'' said CMB's traffic manager, James Sykes. He said that until the GEO reveals its proposals CMB might draw up its own contingency plans to either move the bus stops or provide extra shelter. His comments were echoed by Citybus. KMB said it had given GEO details of bus stops about a year ago. The GEO engineer in charge of the project, Steve Kennedy, is on leave until September. But his boss, chief geotechnical engineer/design, Allan Watkins, confirmed the review was taking place and covered busy roads. ''We have indicated to Transport Department that we would want to review where bus shelters are put,'' he said. Legislator Albert Chan Wai-yip said he was angry and extremely surprised by the delay. ''The GEO promised the Legislative Council's Lands and Works panel the review would be a top priority a year ago. So GEO should have already drawn up procedures to take remedial action on slopes near bus stops. I am extremely surprised. GEO is behaving extremely irresponsibly,'' he said.
