SBB CFF FFS - Ee 3/3 II 16515 electric locomotive

The prototype:

The SBB Ee 3/3^II electric locomotives are visually and mechanically based on the widely used Ee 3/3, but differ through their dual-system capability for operation under 15 kV 16 2/3 Hz and the French 25 kV 50 Hz system.

After the commissioning of the 25 kV electrification in the western part of Basel SBB station and on the Alsace railway, the SNCF lacked its own dual-system locomotives for freight services toward the Muttenz marshalling yard.

As a result, between 1958 and 1960 the SNCF acquired nine locomotives of type C 20151–20159, technically derived from the Ee 3/3 16505–16506.

The locomotives were built by SAAS in Geneva and SLM in Winterthur.

After more powerful BB 20200 locomotives took over duties in 1970, the SNCF sold its nine locomotives to the SBB between 1971 and 1972; over the years they were adapted to SBB standards.

The locomotives were frequently used in double traction, among others in Basel, Bern, Lausanne, Biel, Vallorbe and Delémont. Between 2004 and 2011 all locomotives were withdrawn—except for 16515, which was restored in 2020 by the TEAM C-20155 association and preserved in its original SNCF livery.
