In a historic move to enhance railway safety, Indian Railways has introduced Kavach 4.0, an innovative indigenous safety system, on the Mathura-Kota section of the high-density Delhi-Mumbai corridor. The announcement was made on July 30, 2025, by Union Minister for Railways Ashwini Vaishnaw, marking a significant milestone in India’s quest for safer and smarter rail travel.
Kavach 4.0: India’s Answer to World-Class Train Safety
- Kavach 4.0: Designed at Safety Integrity Level 4 (SIL 4), India’s cutting-edge system to prevent accidents, automatically monitors and controls train speeds.
- Enhanced Visibility: Ensures effective brake application in low visibility conditions like fog, providing vital information to train drivers inside the cabin.
Nationwide Rollout and Training
The nationwide deployment of Kavach 4.0 within six years was announced by the Railway Minister, accompanied by significant training initiatives:
- Personnel Training: Over 30,000 personnel have already received training on Kavach systems.
- Academic Integration: IRISET has partnered with 17 AICTE-approved institutions to include Kavach technology in engineering curricula, fostering a skilled workforce.
Technology Behind Kavach 4.0
Kavach’s advanced technology resembles a full-fledged telecom network, incorporating:
- RFID Tracking: RFID tags placed every 1 km and at signals enable precise train location tracking.
- Communication Infrastructure: Telecom towers with optical fiber connectivity and power supply facilitate continuous communication between key components.
- Emergency Integration: Seamless integration with the braking system ensures automatic brake application during emergencies.
Rigorous Testing and Speed Approval
Following extensive testing, Kavach 4.0 received approval in May 2025 to operate at speeds up to 160 kmph after successful trials in the South Central Railway.
A Strong Push for Passenger Safety
Indian Railways’ substantial investment in safety activities, exceeding ₹1 lakh crore annually, underscores the importance of initiatives like Kavach 4.0 in maintaining a secure railway network.
