Where is ERTMS already being used?

Across many countries in Europe and elsewhere. In Switzerland it is enabling 15-25% capacity increase on a key route with services operating at 125mph. Valuable supply chain experience has already been secured in the UK, following Network Rail’s first ever European Rail Traffic Management System (ERTMS) deployment on the Cambrian Line in 2011. This was augmented in 2018, when the first passenger train ran through the Thameslink core in central London using ETCS with Automatic Train Operation (ATO). Crossrail also features a radio-based control system and sections of ETCS. Great Northern has successfully tested one of its trains using a digital in-cab signalling system for the first time, demonstrating that the system on-board works in a real operational setting.
