Following the delivery of the prototypes in 1964 (initially registered Re 4/4II 11201 - 11206), the production series started in 1967.
50x locomotives are built and delivered during the first batch:
- 49x units are delivered to the Swiss Federal Railways - SBB CFF FFS and are registered Re 4/4II 11107 - 11155;
- 1x unit is delivered to the Swiss Southeastern Railway - SOB and, as it is equipped with a different mechanical transmission (providing a lower top speed and higher traction), is registered Re 4/4III 41.
These units are very similar to the prototypes, except they are 10 cm bigger in length.
From 1969, the locomotives delivered starting with the second batch are half a meter longer compared with the units delivered during the first batch and have two pantographs.
They are registered from Re 4/4II 11156.
Units 11108, 11109, 11112, 11113, 11133 & 11141 are converted for the Swiss Express service and will continue to be registered as Re 4/4II 11108, 11109, 11112, 11113, 11133 & 11141.
