What are the key signaling projects and their costs?
The Ministry of Railways approved projects worth ₹1,364.45 crore to strengthen safety and communication. The investments are spread across different zones to modernize the network:
| Zone | Project Detail | Cost |
|---|---|---|
| Southern Railway | Kavach Version 4.0 on 232 locomotives | ₹208.81 crore |
| Northern Railway | OFC network over 3,200 route km | ₹400.86 crore |
| North Central Railway | OFC network over 2,196 route km | ₹176.76 crore |
| South Central Railway | Electronic interlocking at 49 stations | ₹578.02 crore |
How will the new signaling system improve safety?
The railways are moving toward Direct Drive Electronic Interlocking (DDEI) systems. This technology reduces the need for copper cables and relays, which lowers maintenance costs and protects the system from lightning. The DDEI system ensures that tracks are clear and level crossing gates are closed before a train is allowed to move, minimizing the risk of accidents.
What new audit rules have been introduced?
To maintain high safety standards, the Railway Board ordered a complete audit of signaling systems across the network. Starting April 29, 2026, Senior Administrative Grade (SAG) officers must conduct monthly audits in all zonal railways. These checks aim to identify faulty equipment and ensure that staff are following the correct maintenance procedures for both new and old systems.
Frequently Asked Questions (FAQs)
What is the purpose of the new signaling audits?
