Sick MTR passengers will be offered medical help by untrained platform staff in an effort to stop them pressing carriage alarm buttons and delaying trains. The attendants will wear yellow arm bands and yellow caps and will be stationed at each platform of stops on the Tsuen Wan Line heading for Central from today. They will be on duty during the peak period from 7.30 am to 9.30 am on weekdays 'to offer immediate assistance to those who are not feeling well while riding on the MTR'. A spokesman for the Mass Transit Railway Corporation said the measure was in response to suggestions made by British railway expert Alan Cooksey. Mr Cooksey was brought to Hong Kong last month after a series of train delays, some caused by ill or disgruntled passengers pressing alarm buttons. 'Seeking help from platform attendants is less disruptive and more efficient and effective than pressing the alarm plungers,' said the spokesman. 'They are supposed to offer such help as giving a chair or a cup of water to the passengers, looking after them while waiting for ambulances.' If the pilot scheme is successful it could be extended to other sections of the MTR and to cover other times of the day. But legislator Albert Chan Wai-yip said platform attendants were not enough to help passengers. He said the MTRC should set up another set of alarms for passengers who feel unwell so platform staff could be alerted in advance. The MTRC suggested yesterday that passenger alarms should only be used if there was a fire, explosion, fighting, poisonous gas, robbery, or wilful destruction of train equipment, or if passengers' lives at risk.
