Each four-car train has 335 seats, of which 61 are in first class, and can accommodate a further 110 standing passengers. "The new trains will allow us to increase peak-period seating capacity by around 30% on Bern S-Bahn lines," says Guillelmon.

The trains have low-floor entrances with sliding steps, air-conditioning, CCTV, and electricity sockets in first class. There are spaces for wheelchairs in both first and second class, and a wheelchair-accessible toilet.
