The HGe 4/4 was the first electrical locomotive of the former Furka-Oberalp-Bahn. Today the FO is part of the Matterhorn Gottard Bahn (MGB).
These Locomotives were built in the 1920’s by the Schweizerische Lokomotiv- und Maschinenfabrik (SLM) and Maschinenfabrik Oerlikon (MFO), esspecially for the FO and the Brig-Visp-Zermatt-Bahn (BVZ) as HGe 4/4 I.
In 1940 the FO decided, just like the Rhaetian Railways to electrify the track with 11.000 V AC. These locomotives were built with a lightweight body and oil-colled transformers.
The Cog-system is System Abt. This system is developed by the Swiss Constructor Roman Abt (1850-1933)
The track of the FO was btween Brig and Disentis. Only the numbers 32, 33, and 36 are still in operation. Number 35 was scrapped in 1971 en during 1992 numbers 31 and 34 were scrapped. In 2007 number 37 was scrapped.
