The electric locomotives of the Ae 3/6 series were procured from 1921 to 1929 in several order batches. The locomotive 10664 originates from the SLM and BBC factory halls. Due to their long period of procurement, various technical innovations were installed. This increased the performance of these locomotives from 1,450 kW to 1,600 kW. Thanks to their good running characteristics, the maximum speed could also be increased. This took place in 1929 from 90 km/h to 100 km/h, and, for the more powerful locomotives (from No. 10637) 1937, to 110 km/h after adaptations to the running axle bogie. Locomotive 10664, built in the year 1926, was housed in the Bern, Zurich and Rohrschach depots. From 1990 to 2010, it was run as a historic traction unit by the «Eisenbahnfreunde Zürichsee rechtes Ufer» (Railway Friends of Zurich Lake, Right-hand Bank). It is still used today as an operational historic locomotive in the Rapperswil Depot, and is owned by the Stiftung Historisches Erbe der SBB (SBB
