CITYLINK TramTrain – Das Projekt Saarbahn GmbH
Saarbahn GmbH is one of the 6 operators in the consortium 'TramTrain – Das Projekt' that in January 2022 awarded to Stadler the contract for up to 504 vehicles.

As part of the project, Saarbahn GmbH ordered 28 CITYLINK Tram-Trains with the option of a further 21 vehicles and will be the first operator in the consortium to receive the vehicles. The contract also includes up to 32 years of maintenance. Passenger services are due to start after the test phase in 2025. CITYLINK is a modular, barrier-free light rail vehicle that was specifically designed to connect urban areas with the surrounding region without forcing passengers to switch trains in order to offer them a comfortable journey. The dual-system light rail vehicles can operate on tram routes with 750 V DC and mainline routes with 15 kV AC. Each bi-directional vehicle has three carriage sections and four bogies. Access to the vehicle is barrier-free. Four doors on each side allow quick entry and exit. The interior offers 100 comfortable seats and capacity for 133 standing passengers. The bright and spacious passenger compartment has two large multifunctional zones with space for bicycles and pushchairs as well as reserved areas for wheelchair users
