As a replacement for the Ge 6/6^I “Crocodiles”, the RhB received a total of 23 Ge 4/4^II in two batches in 1973 and 1984. The locomotives already had electronically controlled rectifiers, multiple controls and they can be used together with control cars. On a gradient of 4.5 percent, 185 tonnes can be pulled by one locomotive. From 2004 they were equipped with computer-controlled control electronics. After a second modernization from 2016, they will remain in use for a few more years and can also transport the modern Alvra articulated trains.
