POWER cables along the train tracks at the Botanic Gardens and Farrer Road MRT stations were replaced yesterday without a hitch.
Between 6am and 10am, commuters found their travelling times extended by about 10 minutes.
An SMRT spokesman said that more of such works are expected to take place at other stations next month. The cable replacement programme was prompted by faulty power cables which led to breakdowns on the Circle Line in recent years.
In January, work began to replace more than 1,000 power cables, measuring 120km in total, with new ones that are more resistant to water seepage. This programme, which will improve service reliability and prevent power outages, will cost almost $15 million.
Last Sunday, work was done at Marymount and Caldecott stations.SMRT said the plan to replace power cables at all 30 stations by the end of the year is on track.
Separately, a cracked rail which led to delays on the north-bound track between Braddell and Bishan stations on Saturday was replaced overnight after operating hours. It was completed by yesterday morning. The crack, which appeared in the afternoon, cost commuters an additional 30 minutes of travelling time.
