Six articulated trains have been running on the Albula line since 2016. Passengers benefit from air-conditioned carriages, the latest information systems and low-floor access.

The articulated Alvra trains are equipped with amply proportioned low-floor access with retractable steps, disabled toilet facilities, air-conditioned passenger compartments and the latest information systems. Passenger accommodation consists of 63 seats in first class and 217 in second class, along with 13 folding seats and space for four wheelchairs.

Each articulated train is also equipped, in addition to its first- and second-class seating, with a family section with a children’s play area, and a leisure section for mountain bikers, hikers and sledgers, plus a photographers' viewing area with large picture windows.
