SŽ series 664

[2] They were designed by Electro-Motive Diesel from the USA as type G 26 HW-2 and assembled by Đuro Đaković in 1984 and 1985.

Eight locomotives were awarded for the towing section in Divača, and twelve for the Maribor draw.

It is intended for towing heavy freight and passenger trains on non-electrified lines in Styria, Dolenjska, Istria and The Isonzo Corridor.

An electric generator with a power of 375 kW / 1500 V is installed to heat up to 10 coaches, so they are also used for passenger traffic.

Due to a single cabin, visibility on the line is reduced, so the train is doubled (driver with assistant).
