Thousands of commuters were left stranded on Wednesday evening when Delhi Metro services on the blue line (Dwarka-Noida corridor) were disrupted for over two hours at peak rush time.
A Delhi Metro official said that the snapping of an overhead electrification wire on the route going towards Dwarka led to the problem.
Due to the snag, trains were forced to run at very low speeds and had to stop for several minutes at each station. According to many stuck commuters, the trains were stopping at each station for close to 20 minutes.
Though metro officials made a single line operational between Dwarka and Janakpuri metro stations and ran a short loop service between Janakpuri West and Rajiv Chowk metro stations, the crowd became unmanageable at several locations.
A senior Delhi Metro official said the snag occurred at 6.43pm and the fault could only be rectified by about 9.10 pm.
