After the Ae 4/4 of the Bern-Lötschberg-Simplon Railway, which went into operation from 1944, had successfully proven itself over two decades, further outdated locomotives were due to be replaced at the beginning of the 1960s. While the SBB aimed to purchase Re 4/4ˡˡ with classic direct control and single-phase AC motors, BLS opted for more modern technology with silicon rectifiers and shaft current motors. The locomotives, initially classified as Ae 4/4ˡˡ, and then as Re 4/4 after technical improvements, were built by SLM and BBC and used for both passenger and goods transport on the BLS, GBS, SEZ and BN networks as well as the adjacent SBB routes.
