The East Rail Line is taking a step closer to nature as it approaches 100 years of carrying passengers to the border. The MTR Corporation has adopted an architectural theme that it calls 'In Touch With Nature' for a refurbishment programme on the former Kowloon-Canton Railway line. All materials used to renovate ceilings, walls, floors, telephone stands, advertising panels, customer service centres and platform seats will be earth-toned in warm and natural colours. Wilfred Yeung Sze-wai, MTR Corp chief architect, said the design would take advantage of the line's setting between hills and the sea. Mong Kok East station will be the first station to be completed next year, while Sha Tin station has received partial renovation. Other stations will be revamped on a schedule according to their condition and passenger numbers, with work expected to be finished by 2016. Mr Yeung said the total cost would be determined after studies of the stations and the production of design drawings. He hoped to give each line a different theme. For East Rail, he planned to introduce more daylight and ventilation in stations to optimise the feeling of 'being with nature' for passengers, adding that this would save energy.
