The MTR Corporation will boost services on the Tung Chung line following demands from residents, despite the relatively low number of passengers using the route, a top company official said yesterday. From Monday, trains on the line will run at alternate intervals of eight and four minutes during the morning rush hour, compared with every eight minutes at present. Evening peak services will also be changed from every 10 minutes to every eight minutes. MTR Corp's head of operations, Wilfred Lau Cheuk-man, said the improvement in the service had been made possible with the addition of four new trains to its fleet. 'Once in a while, we hear this request for more frequent services, but we have to consider cost-effectiveness,' Mr Lau said. The Tung Chung line serves an average of 180,000 passengers a day, but Mr Lau said even the most crowded trains during rush hour were only 40 per cent full. 'You may have doubts about this, but I tell you passengers tend to squeeze themselves into the middle train car as they're the nearest to the escalators, while cars on either end are quite empty.' Mr Lau hoped new property developments in Tung Chung would help boost the line's patronage. Tung Chung residents have long complained about the infrequent train services on the route. District councillors have met MTR officials several times to discuss the issue, and a petition was launched in June demanding an improved service. Two of the four new trains are already in service, while the other two are still under inspection. The four will take up the 36 extra runs per day as the number of daily journeys on the route is increased from 240 to 276.
