The Ministry of Railways has sanctioned a fund allocation of ₹233 crore to install modern Electronic Interlocking systems at 21 stations under the Samastipur Division of East Central Railway. This project will replace older signalling technology and pave the way for rolling out Kavach, India’s homegrown automatic train protection system.
What is being done and where
The Samastipur Division will see its existing Panel Interlocking systems upgraded to Electronic Interlocking across 21 stations. Electronic Interlocking is a computer-based signalling technology that replaces decades-old relay mechanisms with digital controls. This shift brings several advantages: the new system is more reliable, diagnoses faults faster, requires less maintenance effort, and allows railway operators greater flexibility in how they manage train movements.
Beyond just upgrading signals, this modernisation sets the ground for deploying Kavach, an indigenous automatic train protection system being developed by Indian Railways. Kavach is designed to prevent accidents by automatically applying brakes if trains approach each other too closely or breach speed limits.
The total project cost stands at ₹233 crore for work across all 21 stations in the division.
What this means for you
If you travel on routes served by Samastipur Division stations, this upgrade should translate into safer and more reliable train operations once implementation is complete. The modern signalling infrastructure will help reduce signal failures and delays caused by technical breakdowns. As Kavach systems come online later, an additional layer of automatic safety features will protect passengers during journeys. Railway staff at these stations will also benefit from easier troubleshooting and maintenance of the new computer-based systems compared to managing older relay-based equipment.
