Anti-Collision Device in Trains & Ultrasonic Broken Rail Detection System

Anti Collision Device (ACD) developed by Konkan Railway Corporation Limited (KRCL) was provided as a pilot project on 1736 Route Kilometres on Northeast Frontier Railway (NFR).

Complex operational and technical problems were experienced during these trials which could not be fully resolved by KRCL due to design limitation of ACD. As such, proliferation of ACD is not contemplated.

Indian Railways have planned for alternative Automatic Train Protection (ATP) Systems and in this regard following pilot projects have been taken up for evaluating their technical suitability on Indian Railways.

1. Train Collision Avoidance System (TCAS) – Pilot launched on South Central Railway in Lingamapalli-Vikarabad-Wadi & Vikarabad-Bidar (250 Route Kms) section of Secunderabad Division.

2. Train Protection Warning System (TPWS) – Pilot successfully implemented on:

(i) Chennai-Gummidipundi suburban section (50 RKms).

(ii) Nizamuddin-Agra main line section (200 RKms).

(iii) Kolkata Metro Dum Dum- Kavi Subhash section (25 RKms).

It has been decided to undertake trial of Ultrasonic Broken Rail Detection system (UBRD) on Northern Railway and North Central Railway over 25 Km of track each.
