Indian Railways has sanctioned key infrastructure and capacity augmentation projects worth over 895 crore rupees to strengthen railway bridge infrastructure and enhance metro rail power systems. In a major step towards enhancing metro rail capacity, works worth 671.72 crore rupees have been sanctioned for strengthening the North-South Corridor of Kolkata Metro Railway. This includes provision of seven new Traction Substations at a cost of over 291 crore rupees.
The Kolkata Metro system, built in the 1980s, was originally designed to support train operations at a frequency of about 5 minutes. With the sanctioning of this project, Kolkata Metro will be enabled to operate at a 2.5-minute headway, significantly enhancing line capacity and service frequency.
A project costing around 223 crore rupees has been approved for the construction of bridge between Madhukunda-Damodar section, along with associated yard remodelling and track works in bridge approaches under South Eastern Railway. These projects represent a significant step towards modernisation, safety enhancement, and capacity expansion across Indian Railways.
