Transporter wagons were used extensively for a great many years in Germany, Austria (gauge 760 mm (2 ft 5 15⁄16 in)), Switzerland (1,000 mm (3 ft 3 3⁄8 in) Brünigbahn) and Sweden (gauges 802 mm (2 ft 7 9⁄16 in), 891 mm (2 ft 11 3⁄32 in), and 1,067 mm (3 ft 6 in)). This was a boon especially to exchange traffic on the extensive Swedish 891 mm network, which once comprised almost 2,000 km (1,243 mi) - in fact a number of local country areas in southern Sweden had nearly no 1,435 mm (4 ft 8 1⁄2 in) (standard gauge) lines at all, just narrow gauge ones. On the other hand, Rollböcke were not much used there.
