New Delhi: The backend warriors of Indian Railways have fully availed the opportunity provided by suspension of passenger services due to pandemic of COVID 19 to successfully executed more than 200 long pending maintenance works including yard remodeling, repair and re-girdering of old bridges, doubling and electrification of rail lines and renewal of scissor crossovers.

These works were pending for several years and were confronting Railways with severe bottlenecks. They were planned during lockdown period considering it ‘Once in a lifetime opportunity’ to wipe out these maintenance arrears and take up the execution of work without affecting the train service.
These works taken up for removal of bottlenecks and enhance safety include 82 rebuilding/rehabilitation of bridge, 48 limited height subway/road under bridge in lieu of level crossing gate, 16 construction/strengthening of foot over bridge, 14 dismantling of old foot over bridge, 7 launching of road over bridge, 5 yard remodelling, 1 commissioning of doubling & electrification and 26 other projects.
