Built by SLM and SAAS between 1941 and 1952, this robust 29-tonne machine served the Emmental Burgdorf Thun Bahn (EBT) and later the Swiss Federal Railways (SBB).

With a power output of 257 kW and a top speed of 60 km/h, the Te III, with its 0-4-0 configuration (or B' according to UIC notation), was an agile and efficient locomotive for shunting and freight services.
