The Ae 3/6 II design was based on prototype locomotive Be 3/5, however with one transformer only. The series were built in four production blocks from 1923 to 1926 by the Schweizerische Lokomotiv- und Maschinenfabrik (SLM) and the Maschinenfabriek Oerlikon (MFO). The single transformer construction resulted in an a-symmetric frame so that a 2-C-1 wheel arrangement had to be selected. The driving force of two traction motors is being transferred to two blind axles, which are connected to driving yokes. The latter drives the middle axe, that is linked to the other two driving axles by coupling rods.
The regulator type for controlling the traction force (step-switches with high-tension chokes) had been used earlier by MFO on an experimental base by some units of the Ce 6/8 series. Later on, the type was applied to all Ce 6/8 engines. The traction motors with a diameter of ca. 1,900 mm (6‘ 3“) and a weight of 10 long tons were the heaviest traction motors ever in SBB locos. From 1929 on the power distribution gear went through a number of modifications that enabled the maximum speed to be increased to 100 km/h, like other Swiss rod-driven types.
Engine no. 10439 was classified as a historical locomotive object in 1976.
