The MTR Corp has again been urged to offer desperate passengers relief by installing public toilets in stations. Lawmakers at a Legco committee meeting discussing the MTR Corp and Kowloon-Canton Railway Corporation merger bill said the MTR Corp should improve services by building public toilets. But the deputy secretary for the environment, transport and works, Patrick Ho Chung-kei, said the rail operator had found that technical problems with drainage and hygiene were too difficult to overcome. 'The company says construction of toilets involves drainage work,' Mr Ho said. 'There are also complicated technical problems if construction work has to be done at platforms and the concourse for installation of toilets. A hygiene problem is also another concern, such as a bad smell.' However, Mr Ho said the operator would try installing toilets at new lines and outside existing stations. Some KCRC stations have public toilets, but only Yan O, the last MTR station before Disneyland, has public toilets. Legislators Albert Chan Wai-yip and Emily Lau Wai-hing said this was not acceptable. 'Why can the MTR expand train stations for building more shops but not toilets?' Mr Chan asked. 'Just take a look at Central station. You can see lines of shops are constructed there. There is space for shops but no space for building toilets? 'I have been talking about this for 20 years. Travelling time between Chai Wan and Tsuen Wan is about an hour, and it is painful for passengers who have an urgent need to go to the toilet.' He pointed out that many mothers allowed their children to urinate outside Lai King MTR station and the smell was very unpleasant. 'It seems that the MTR is willing to make technical changes to its stations only when there are profits to be made but not for the convenience of passengers,' Mr Chan said. Ms Lau, of The Frontier, said the MTR Corp was being inconsiderate. 'The MTR installed toilets for the Disney line because many children use the service. But do you see there are a lot more children riding trains along all other lines?' Unionist legislator Wong Kwok-hing urged the rail operator to learn from the underground system in Taiwan, where toilets were available. 'Toilets can be found at every station, and they are all very clean,' he said.
