East Coast Digital Programme introduced the European Train Control System (ETCS) as an overlay between Welwyn and Hitchin to allow trains to operate through it using conventional or digital in-cab signalling.

The East Coast Digital Programme (ECDP) is delivering the next generation of train travel – creating a better performing East Coast Main Line for passengers and everyone else who uses and depends on it. As part of the Programme, traditional lineside signals will be replaced with state-of the art digital signalling using a system called ETCS (European Train Control System) to create a safer, more flexible, efficient and greener system - with less delays and more capability. The East Coast Main Line will be Great Britain’s first intercity mainline to be upgraded to digital and it lays the foundation for further improvements across the network. The ECDP brings together 32 industry partners, who are collectively working to create a more efficient railway fit for the future.
