System based on radio waves: Railways to test European signalling system

The Indian Railways has selected the 850-km route between Mathura and Vadodara to test the European Train Control System (ETCS) level 2, as part of the transporter’s plan to modernise the entire signalling system on its network to enhance safety, a key focus area. Installations for the test will cost the railways more than Rs 2,000 crore.

The railways has already tested the ETCS level 1 on 342 km (Agra-Delhi, 200 km; Chennai suburban railway, 117 km; and Kolkata’s Metro Railway, 25 km), wherein locomotives are fitted with screens that receive intermittent messages about signals ahead through track-side devices. This mitigates the risk of locomotive pilot’s error of running over signals due to fog or human error, or over-speeding as the locomotive comes to a halt upon making an error.

In level 2, messages are conveyed continuously to the screen fitted on-board a locomotive through radio waves. According to a railway official, the per km cost of implementing the ETCS level 2 is 30% higher compared with the ETCS level 1. Read More
