Stadler will supply 36 CITYLINK Tram-Trains and 35 FLIRT passenger trains to Transport for Wales Rail Services.

The 36 tram-trains that will operated on the Core Valley Line relying on 25 kV as well as battery power will be developed and manufactured by Stadler Valencia. The bidirectional three-car light rail vehicles cover tramway applications and full train regional operations at 100km/h. They have a length of 40 m, capacity for 257 passengers and 6 multifunctional areas for bicycles or for PRM.

Of the 35 FLIRT units, 11 will be diesel-operated and used on South Wales Metro services. The other 24 FLIRT units will be tri-mode, capable of running on diesel, overhead electric wires and battery power. Coming on-stream in 2023, they will be powered by electricity to the north of Cardiff and diesel to the south, providing a cross-city connection.

The use of batteries on tram-trains and tri-modes is an innovative and cost-effective way of providing a fully electric, environmentally-friendly service north of Cardiff by enabling ‘smart electrification’ of the infrastructure.
