The first phase of ECDP has successfully introduced in-cab digital signalling to the commuter route between Finsbury Park and Moorgate in central London, with the lineside signals removed in May 2025.
The testing work taking place in February is the latest step in a process towards operating the first digitally signalled passenger trains on the main line through the Welwyn to Hitchin section from later this year. The rigorous process involves testing of the lineside equipment, and its interaction with the equipment on board the train, and with the signalling control in York ROC (Rail Operating Centre).
