A signalling failure briefly marred the charity trial run of the new Ma On Shan railway line yesterday, holding up services for three minutes, but the day was still adjudged to have been a success, with 10,000 people using the line every hour. Hundreds of people waited with cameras poised for the first train on the nine-station Kowloon-Canton line, which carried 1,000 passengers on the inaugural run at 10am. Fares on the route are $5.80 from any Ma On Shan station to any East Rail station between north of Tai Wai and Sheung Shui, and $11 from Tai Wai to Tsim Sha Tsui East. Concessions of 50 cents to $1 on Octopus cards apply when minibuses are used after rail journeys. While many passengers welcomed the new line, some were concerned the Tai Wai interchange may become overcrowded in rush hours, while others said commuters may prefer cheaper buses that did not require an interchange. But KCR chief Michael Tien Puk-sun said he was confident that Tai Wai station could handle large numbers of passengers at peak hours and that cancellation of cross-harbour bus services would bring more benefits to rail users. 'If more passengers take the rail, then there is scope for us to set lower fares,' he said. But Ma On Shan residents urged the transport department not to cancel the bus routes.
