In-cab signalling to be tested at speed on ECML

On Sunday 25 August, the first long-distance train will test newly installed in-cab signalling at high speed on the East Coast Main Line between Welwyn Garden City and Hitchin.

The testing of the European Train Control System (ETCS) is expected to involve both a Grand Central Class 180 passenger train and a Network Rail Class 43 measurement train.

This is in preparation for trains to run on this route using digital signalling from late 2025. 

For the testing to be carried out under controlled conditions, the railway needs to be closed in and around the affected section.

Buses will replace passenger services, and both suburban and long-distance services will be affected, so anyone planning to travel on the Sunday of the bank holiday weekend is advised to check with their train operator or www.nationalrail.co.uk
