Electric operated tram-trains, which draw electricity from wires overhead, will be used for the new rail system.
According to Cardiff Council, the hybrid-electric vehicles (HEVs) are well-suited to the city’s pre-existing infrastructure, diverting operations to onboard batteries in areas lacking energised overhead wires.
It’s hoped that the HEVs will provide a more sustainable public transport network for the Welsh capital city into the future.
A new £100m depot and Metro Control Centre will also be built in addition to the Crossrail project near Taff’s Well railway station to house the tram-trains.
The Cardiff Crossrail programme forms part of the wider South Wales Metro Project, a multimillion-pound project that aims to create an integrated network of bus, rail and active travel that will improve connectivity and make sustainable travel easier across South Wales.
A total of 11 projects in Wales have receive grants worth £208m from the UK government’s second round of Levelling Up funding.
