The South Wales Metro railway lines are currently testing brand-new tram-trains that are set to "revolutionise" public transport. The Citylink tram-trains are 40m long and can carry more than 250 passengers with the ability to run at 100km per hour on rail.
The class 398 tram trains are being tested for the first time as working passenger trains. It's hoped they will come into wider service on the South Wales Metro in 2024. In total there will be 36 of the tram trains which have been build by leading Swiss manufacturer Stadler at their factory in Valencia.
The trains are equipped with traction battery packages, allowing them to operate over non-electrified sections of track in addition to those with overhead supplies. The tram-trains are high-floor vehicles and feature spacious, bright and air-conditioned passenger compartments with six multifunctional areas for bicycles as well as seats for people with reduced mobility and two wheelchair passenger spaces.
