Train passengers will have to continue paying an extra 10 cents on each ride to cover the cost of installation and maintenance of platform screen doors even after the MTR has finished fitting the doors next year. Andrew McCusker, deputy operations director of the rail operator, told lawmakers on the railways subcommittee yesterday that the 10-cent surcharge was needed to pay for the upkeep and maintenance of the doors. 'There are lots of ongoing costs in terms of the platform screen doors,' he said. 'And going into the future they will have to be renewed and upgraded, as all assets are.' His remarks angered some lawmakers, who said the fee should not be applied forever and should only be used for the construction cost of the doors. The MTR has added the charge since 2000 for people who use the Octopus card to pay for their rides. The company had estimated the surcharge would pay for about half of the $2 billion construction cost of the doors. It had collected $300 million so far from the 10-cent fee, Mr McCusker said, but he did not say when MTR passengers could stop paying it. Legislator Lau Kong-wah said: 'This is like cheating in a way because at the time when [the company] spoke with us, they did not mention all the costs involved. Everyone had the impression [the fee] was for the construction cost.' The MTR began installing screen doors on platforms to separate passengers from train tracks in 2001. It has completed the work at 24 underground stations and has six more to go before the project finishes early next year. Mr McCusker said next year the company would start studying how to install the screens at above-ground stations. Separately, Mr McCusker told the subcommittee yesterday that there was no room for giving passengers group or family discounts on the Disneyland Resort Line, which is scheduled to open in September. Lawmakers argued that the rail operator should give the public more concessions on the rides because the government had helped to finance the project by waiving its claim for $798 million in dividends over a few years to which it was entitled as a shareholder. They also questioned whether the four-car train line would be able to transport all the passengers going to Disneyland in the early morning rush hour and late night after the fireworks finished. Deputy Secretary for Transport Cathy Chu Man-ling said the train line had a capacity of more than 10,000 passengers per hour, which should be enough to handle Disneyland's forecast of 11,000 hourly visitors during the morning hours. Aside from the train line, Disneyland visitors would also be able to take buses and coaches to get to the theme park. Ms Chu said minibuses have been ruled out because of their low capacity for passenger numbers.
