1946

January 22nd

After the end of Second World War, the Swiss Federal Railways (SBB CFF FFS) are looking to modernize their locomotives fleet for passenger traffic and replace the Ae 3/6I units.

The new locomotive had to be able to:
- tow 300-ton trains on ramps of 12‰ at a speed of 110 km/h;
- brake 300-ton trains on ramps of 38‰;
- tow 460-ton trains on ramps of 10‰ at a speed of 75 km/h.

Bern–Lötschberg–Simplon Railway (BLS) locomotive Ae 4/4 is a source of inspiration.

The chosen locomotive for this purpose was the Re 4/4 locomotive built by Schweizerische Lokomotiv- und Maschinenfabrik (SLM) for the mechanical part and by Maschinenfabrik Oerlikon (MFO), Brown, Boveri & Cie (BBC) and Société Anonyme des Ateliers de Sécheron (SAAS) for the electrical part.

The unit cost for the locomotive was 700 000 Swiss francs.

The locomotive is equipped with a gangway connection for easier access when used in multiple control or in a shuttle train.

The first batch of 6x Re 4/4 I units is delivered between January 22nd and June 26th, 1946. They are registered 401 to 406.

All locomotives from this series are delivered in a green livery.
