Phase-I of the Rapid MetroRail Gurgaon Limited (RMGL), a network of 5.1 km connecting Cyber City, National Highway-8 and Sikanderpur Metro station, is expected to become operational in April despite slowdown of work due to extreme cold, said RMGL managing director Sanjiv Rai here on Thursday.

“Due to extreme cold conditions prevailing over the past few weeks, the de-stressing and welding of metro tracks have been delayed for a couple of weeks and work on a one-kilometre stretch is still pending. We also faced labour problems due to cold condition.
