The Südbahn class 480 was a 0-10-0 freight locomotive that was based on the classes 180 and 80. While the former ones had been limited to a lower axle load, the 480 could utilize the network's maximum of 14.5 tonnes, allowing for a bigger boiler. Only six were built and the last three were directly delivered to the BBÖ due to the financial problems of the Südbahn.
Their main task was helper service on the Semmering. In 1938, they received the numbers 57 601 to 57 606. After the war, the ÖBB made them class 257. In 1957, three were equipped with Giesl ejectors. Three years earlier, the first one had already been retired and the last one was retired in 1966. Today, 257 601 is still existing in an non-operational state and unfortunately, 257 605 has been scrapped in 2006.
