They are designed to operate on the international rail network at speeds of up to 160 km/h. The interior is divided in 11 compartments, 6 seats each.

Instead of air conditioning like the Eurofima coaches, these cars were fitted with a Friedmann air heating system so they also received opening windows (the Eurofima coaches had fixed windows).
