MTR Corp is to spend HK$21 million renovating two stations in its latest bid to boost rail income in a deflationary climate. The focus of the renovation at Choi Hung and Tsing Yi stations is on increasing retail space to maximise commercial use of the concourses. Jeny Yeung Mei-chun, MTR Corp's marketing and business development manager, said: 'We have some space at station concourses lying idle, so why not turn it to better use? 'Renovations at other stations are also in the pipeline.' With the HK$25 million refurbishing work at the Prince Edward station close to completion, renovations will start at Tsing Yi in the second quarter and Choi Hung in June. Choi Hung station will undergo a HK$15 million facelift with retail space being increased three-fold to 220 square metres. At Tsing Yi, the retail space will be expanded 45 per cent to 676 square metres at a cost of HK$6 million. Ms Yeung said retailers had reacted positively to the new shopping space, which was about 40 per cent leased at Tsing Yi station and 30 per cent at Choi Hung. 'We expect more leases coming up after the [Lunar] new year,' she said. Although retailers were suffering from the spending downturn, MTRC had an occupancy rate at its 49 stations of about 90 per cent, Ms Yeung said. 'It is a matter of location. Shops in prime locations are still much sought after.' In the second half of the year, Wan Chai and Tsuen Wan stations would be renovated, she said. Causeway Bay station was also a potential renovation target.
