Vande Bharat & Gatimaan Express Back at 160 Kmph! How Kavach 4.0 Just Unlocked India’s Fastest Train Route

In the biggest Indian Railways latest news on the Delhi to Agra train speed upgrade, the Vande Bharat 160 kmph speed and Gatimaan Express 160 kmph operations are set for a major comeback after the successful trackside installation of the Kavach 4.0 Indian Railways automatic train protection system. Following RDSO Kavach safety trials, eight premium trains restricted to 130 kmph since June 2024 will reclaim their top speeds, while Mission Raftaar 160 kmph upgrades and the Delhi Howrah Kavach update alongside the Delhi Mumbai 160 kmph train corridor expand high-speed rail travel far beyond Agra.

India’s fastest semi-high-speed trains are getting ready to roar back at their top operational speed of 160 kmph between New Delhi and Agra. Agra Division Divisional Railway Manager (DRM) Gagan Goyal confirmed that Indian Railways has completed trackside installation of the indigenous Kavach Automatic Train Protection (ATP) system on the Delhi–Agra stretch. Currently, the Research Designs & Standards Organisation (RDSO) is conducting final safety trials, and once RDSO gives the green signal, trains will move up from the restricted 130 kmph limit back to 160 kmph.

Why Were Trains Slowed Down to 130 Kmph?

Until mid-2024, the Delhi–Agra route was the only corridor in India where trains operated commercially at 160 kmph, allowing the Gatimaan Express to cover the Hazrat Nizamuddin–Agra Cantt journey in just 100 minutes. However, following the Kanchanjunga Express accident, the Railway Board issued an official directive on June 24, 2024 (Letter No. 2021/Sig/Kavach/Vande Bharat), capping the maximum speed at 130 kmph until the SIL-4 certified Kavach system became fully operational. According to an official RTI reply, eight premium services—Gatimaan Express (12049/12050), Bhopal Vande Bharat Express (20171/20172), Khajuraho Vande Bharat Express (22470/22469), and Bhopal Shatabdi Express (12002/12001)—have been running at 130 kmph under this safety mandate.

How Kavach 4.0 Protects High-Speed Trains

Certified to Safety Integrity Level 4 (SIL-4), Kavach 4.0 uses Radio Frequency Identification (RFID) tags fitted along the railway tracks, optical fibre networks, telecom towers, and station control units to monitor train movement continuously. If a loco pilot misses a red signal or exceeds speed restrictions, Kavach automatically applies the brakes to prevent collisions. Indian Railways commissioned Kavach 4.0 on the 35-km Tughlakabad Junction Cabin–Palwal section in January 2026 and subsequently on the Mathura–Agra Cantt stretch, leading up to the ongoing integrated trials on the Delhi–Agra corridor.

Not Just Agra—160 Kmph Expansion Across India

The high-speed push does not stop at Agra Cantt. In September 2026, Indian Railways commissioned Kavach across the 52.5-km Agra Cantt–Dholpur section (installing 720 RFID tags) as well as the Gwalior–Virangana Lakshmibai Jhansi route under North Central Railway. Under Mission Raftaar, the Ministry of Railways has already commissioned Kavach 4.0 across 2,633 route kilometres—covering 1,423 route km on the Delhi–Mumbai corridor (including Palwal–Mathura–Kota–Vadodara–Virar, backed by a 596 track-km 2×25 kV traction power upgrade in Kota Division) and 1,210 route km on the Delhi–Howrah corridor (where 160 kmph Vande Bharat Kavach trials have already succeeded on the 175-km Chipiyana Buzurg–Tundla section). Looking further ahead, the proposed Northern Bullet Train Corridor plans to slash the Delhi–Agra travel time to just 59 minutes.
