Alstom has secured a major regulatory milestone in the deployment of digital signalling technology in the United Kingdom, with Grand Central’s Class 180 train fleet receiving Authorisation for Placing into Service (APiS) for its first-in-class installation of the European Train Control System (ETCS).
The approval for train No. 180108 marks the first passenger fleet retrofit of its kind under the programme and clears the way for the remaining nine vehicles to progress towards operation with ETCS-enabled digital signalling. The milestone brings the introduction of digitally signalled high-speed passenger services on the East Coast Main Line (ECML) closer to reality.
Grand Central, the open-access rail operator owned by Arriva Group, operates the Angel Trains-owned Class 180 fleet. Following the approval, the trains will undergo software updates before entering an extended 50,000-mile fault-free running programme scheduled to begin in December. Grand Central drivers are also being trained to operate ETCS-equipped trains in Level National Train Control (L-NTC) mode on conventionally signalled routes.
Steve Wilson, Project Director at Alstom, said receiving APiS for the Class 180 fleet was a significant achievement following years of technical development and collaboration. He acknowledged the contributions of Alstom, Grand Central, Angel Trains, the National Joint ROSCO Project and the East Coast Digital Programme partners. Wilson said the next phase would focus on supporting the fleet through fault-free running, with the objective of enabling ETCS Level 2 operation on the East Coast Main Line in 2027.
The introduction of digital signalling through the East Coast Digital Programme (ECDP) is intended to improve railway efficiency, reliability and environmental performance over the long term. ETCS supervises train speeds and can automatically bring a train to a stop when required, strengthening operational safety.
Built by Alstom in the UK between 2000 and 2001, the Class 180 trains belong to the company’s Coradia family. The fleet is expected to begin operating with digital in-cab signalling at ETCS Level 2 on the ECML section between Welwyn and Hitchin by spring 2027. Alstom provides round-the-clock maintenance for the trains from its Crofton Depot near Wakefield in West Yorkshire.
Chris Hobden, Programme Director for ECDP at Network Rail, described the approval as an important achievement for the retrofit programme. He said it would support the progressive introduction of digital signalling on the ECML and help prepare the way for other major passenger fleets to adopt the technology between Welwyn and Hitchin during 2027.
The ECDP is a major railway modernisation initiative aimed at introducing digital in-cab signalling across the southern section of the East Coast Main Line. In 2025, the programme delivered the UK’s first signal-free commuter railway between Finsbury Park and Moorgate.
Since August 2026, some Great Northern services have also begun operating with digital signalling on the Welwyn-to-Hitchin section. Further fleets and services are expected to transition to the technology during 2027, supporting the wider rollout of digital signalling across the route. The Class 180 approval provides an important reference point for subsequent passenger fleet retrofits and the continued introduction of ETCS technology across the UK’s rail network.
