The Re 420, originally (and still widely called) Re 4/4 series are the most common electric locomotives of the Swiss Federal Railways. They are used for passenger services throughout Switzerland alone or in pairs. For freight services, they are sometimes paired with the Re 620, especially in mountainous regions. That pairing is referred to by the term Re 10/10.

The Re 420 locomotives were produced over a period of 21 years, from 1964 to 1985.

When Südostbahn could buy before delivery one of the first batch of 50 locomotives, it decided to have the gear modified for higher traction but lower speed. This locomotive 41 (now SBB 11350) was followed by a batch of 20 Re 4/4 ordered by SBB (but three of them were for some years SOB 42–44). Later the predecessors of (EBT-VHB-SMB) ordered a total of five Re 4/4 (111–113, 141, 181, later 111–115) that are now working as Re 436 111–115 for Crossrail.

Six Re 4/4 have been equipped with a wider pantograph wiper in order to conform with DB and ÖBB standards, which allowed these units to operate EuroCity trains over the border to Bregenz and Lindau.

The last series was rebuilt for use in Germany and Austria, not only with a different pantograph but also Indusi and other things necessary for use abroad. These locomotives are classified Re 421 and are lettered for SBB Cargo but also pull passenger trains to Bregenz and Lindau.

30 locomotives of the passenger division (201–230) will be rebuilt for peak hour services with double deck cars in S-Bahn Zürich, starting in 2011. A consist will be built up by 6 (7 consists) or 10 (6 consists) double deckers plus one locomotive at each end.

12 locomotives have been withdrawn by 2010, 96 locomotives are owned by the passenger division, 6 by BLS and all others by SBB Cargo
