Kevin Kung, 15 Ying Wa College No. It would be a huge project, and the cost might be passed on to passengers who are unlikely to support such a move. The MTR began installing screen doors at its stations in 2002 with the aim of improving passenger safety and ventilation. All underground stations are now safer and quieter as a result. But this does not mean that KCR stations should follow such a policy. Most open-air MTR stations don't have screen doors. At the moment, only the East Tsim Sha Tsui Station on KCR's East Rail network has a partition. The company provides a vital rail link to the mainland. Many people use the stations along this line to load and unload goods. To facilitate operations, some stations have curved platforms with a large gap. Screen doors may affect the drivers' view and pose a danger to passengers. Moreover, the KCR may be forced to raise prices to meet the high costs. I am sure the majority of Hong Kong citizens will not approve of a fare rise. Statistics show that there have been very few cases involving people who have fallen onto the rail tracks. But to avoid accidents, the East Rail should increase the number of helpers at stations. There should also be clearer signs to help people go to the right platform. Annie Tai, 16 Shung Tak Catholic English College Yes, there are many advantages of installing screen doors. The platforms would be cleaner and quieter and passengers would have a safer ride. It would also help train drivers stick to their schedule because less accidents would take place. So, if screen doors are such a convenient addition, why don't we see them at every KCR station? They cost too much. According to the article 'MTR's 10-cent door levy to continue' (South China Morning Post, May 7, 2005), each MTR passenger pays 'an extra 10 cents on each ride to cover the cost of installation and maintenance of platform screen doors'. It seems practical for a company to be concerned about costs, but isn't the safety of its passengers more important? People are still taking the MTR although they have to pay 10 cents more. Earlier this month, a woman died instantly when she accidentally stepped beyond the yellow line at a KCR station and fell on to the tracks. Her son, who tried to save her, was also hit by the train and seriously injured. I don't mind spending a little more to help avoid such tragedies. I understand that some outdoor KCR platforms are not suitable for installing screen doors. There is an alternative: the platform screen-gate system used by Westinghouse in Britain. Where there is a rail, there is a way! Safety comes first.
