Indian Railways has approved a set of infrastructure projects across three eastern and northern states with a combined investment of approximately Rs 675 crore, according to official announcements. The projects include the construction of a bypass line in West Bengal, the installation of electronic interlocking systems in Bihar, and the deployment of the indigenous train protection system Kavach in Uttar Pradesh.

The initiatives were described by the Ministry of Railways as measures to improve operational efficiency, strengthen safety, and support freight movement on sections that have been operating at high utilisation levels.

Adra-Joychandipahar bypass line

The largest of the three approvals, in cost terms, is the construction of an 11 km bypass line between Adra end and Joychandipahar in South Eastern Railway, at an estimated cost of Rs 272 crore, as reported by ANI.

The bypass is expected to eliminate existing operational bottlenecks and surface-crossing detentions on the Adra-Joychandipahar section. ANI reported that the existing network on this section operates at about 71 per cent utilisation, and that the bypass is intended to relieve pressure on freight movement by separating through traffic from surface-crossing conflicts.

The project is part of the Energy and Mineral Corridor identified by Indian Railways. ANI reported that the construction is expected to support the movement of iron ore linked to SAIL's projected requirement of 23.40 MTPA, as well as coal traffic expected from BCCL.

According to the railways, the bypass will enable an additional traffic volume of 8.88 MTPA upon identifier: FREIGHT_FLOW_01

The Indian Express reported that the line capacity on the section is currently 47.50%, which is expected to increase to 56.45% by 2028-29.

Bihar signalling upgrade

The railways has also approved the installation of Electronic Interlocking (EI) at 21 stations in the Samastipur Division of East Central Railway, at a cost of Rs 233 crore, as reported by The Indian Express.

The project involves replacing panel interlocking systems with modern computer-based electronic interlocking technology. The railways said the new system offers higher reliability, quicker fault detection, easier maintenance and greater operational flexibility.

The upgrade is expected to strengthen signalling infrastructure across the division and support the rollout of Kavach, the country's indigenous train protection system.

Kavach deployment in Uttar Pradesh

In Uttar Pradesh, the railways has approved the installation of Kavach Version 4.0 on the remaining 712 route kilometres of the Moradabad Division of Northern Railway, at a cost of Rs 170 crore, as reported by The Indian Express.

The railways said that the deployment will add to the existing coverage of the automatic train protection system and improve safety across the division.

Broader context

The three approvals come as Indian Railways continues to expand freight infrastructure and modernise signalling systems across its network. The bypass in West Bengal, the electronic interlocking upgrade in BiharMtractor and the Kavach deployment in Uttar Pradesh together account for sanctioned expenditure of Rs 675 crore.

The projects were announced through an official release from the Ministry of Railways.
