SBB Re 4/4
Re 4/4 is the type designation for four-axle (Bo'Bo ') express train and universal locomotives without running axles in Switzerland. The Swiss Federal Railways (SBB) procured different types, which were provided with an index with Roman numerals to distinguish them.
The manufacturer of the mechanical part of practically all Swiss locomotives up to 1997 was the Schweizerische Lokomotiv- und Maschinenfabrik (SLM) in Winterthur (mechanical part, locomotive body ). The electrical part came from what was then Brown, Boveri & Cie (BBC), later Asea Brown Boveri (ABB), and from Maschinenfabrik Oerlikon (MFO) and Société Anonyme des Ateliers de Sécheron in Genève (SAAS), which later became part of the BBC .
Re 4/4 I (Re 410)
→ Main article: Re 4/4 I.
The first Re 4/4 I came into operation shortly after the Second World War . By 1951 a total of 50 locomotives in two versions were put into service. Today there are no longer any locomotives in regular service with the SBB, until December 2004, some locomotives in Basel SBB were still used as shunting locomotives.
Re 4/4 II (Re 420 / Re 421)
→ Main article: Re 4/4 II
The Re 4/4 II is still the largest series of locomotives that are more or less the same in Switzerland. Accordingly, it is used in all train categories, but is increasingly found in freight transport. It has a maximum speed of 140 km / h. The total of 277 locomotives were put into operation between 1964 and 1985.
Re 4/4 III (Re 430)
→ Main article: Re 4/4 III
This variant of the Re 4/4 II is only used in freight traffic. The changed mechanical transmission reduces the speed to 125 km / h, but increases the tractive effort. The first locomotive was delivered to the Schweizerische Südostbahn (SOB) in 1967 , and in 1971 20 locomotives came into service with the SBB. Another 5 locomotives went to the EBT group.
Re 4/4 IV (Re 440)
→ Main article: Re 4/4 IV
This locomotive with thyristor control was built as a prototype for future purchases by the SBB in four copies and had a maximum speed of 160 km / h. Finally a series Re 4/4 II was built again and then switched to converter technology ( SBB Re 450 and Lok 2000 or SBB Re 460 ). Therefore the Re 4/4 IV went to the Schweizerische Südostbahn (SOB), where they operate as Re 446 .
More locomotives
Other locomotives were also designated as Re 4/4, for example the Re 456 (originally BT, SZU and VHB; today SZU and SOB) and Re 465 (BLS) used by the private railways .
The SBB Re 450 and SBB Re 460 had the designation Re 4/4 V and Re 4/4 VI in the planning phase .
