The SNCF class BB 20005 locomotive was a prototype locomotive of the BB25150/BB25200 series, transformed from the damaged BB16028 in 1961. After the end of its test period in 1975 it was reinstated with its original equipment under its original number BB16028.
After successful tests with BB20004, prototype of BB25500 locomotives, another new series of dual-voltage locomotives was ordered by SNCF: the BB25150 and BB25200 series. These had a higher power than their predecessors, and in order to test the new parts and technology it was decided to rebuild a BB16000 locomotive into dual-voltage.
BB20005 differed from previous prototypes in the way that it had a both complete AC and DC equipment, previous locomotives only having a complete AC equipment and a small DC equipment, limiting their power under 1.5 kV.With a full AC and DC equipment, BB20005 developed nearly 85% of its power under 1.5 kV, which was a great achievement at that time, knowing that only 2 years before BB20004 developed only 45% of its power under 1.5 kV.
The prototype helped to develop the bogies of the 2 'BB Jacquemin ' series: the BB25150 series which had bogies for 130 km/h (81 mph) and were lower geared (to pull heavier freight trains) and the BB25200 series which had bogies for 160 km/h (99 mph) and were higher geared (for lighter passenger trains and to operate in push-pull mode).
The SNCF BB 26000 locomotives are a class of dual voltage, four axle B'B' electric locomotives capable of a top speed of 200 km/h built by GEC Alsthom between 1988 and 1998 for SNCF. The locomotives are also commonly known as the Sybics.
Prima is a family of railway diesel and electric locomotives built by Alstom. During the late 1990s, manufacture of the type had commenced; by 2008, Alstom had reportedly sold 1,750 Prima locomotives. In 2009, the second generation Prima II was launched. During 2013, the Prima H3 diesel/battery hybrid locomotive was launched.
The SNCF BB 20011 and SNCF BB 20012 were electric locomotives used for testing, built by Alsthom between 1985 and 1986. The two locomotives were the synchronous dual-voltage prototypes for Class BB 26000.
Alstom Traxx is a modular product platform of mainline diesel-electric and electric locomotives produced originally by Bombardier Transportation and later Alstom, which was built in both freight and passenger variants. The first version was a dual-voltage AC locomotive built for German railways from the year 2000. Later types included DC versions, as well as quadruple-voltage machines, able to operate on most European electrification schemes: 1.5/3.0 kV DC and 15/25 kV AC. The family was expanded in 2006 to include diesel-powered versions. Elements common to all variants include steel bodyshells, two bogies with two powered axles each, three-phase asynchronous induction motors, cooling exhausts on the roof edges, and wheel disc brakes.
The SNCF class BB 15000 is a class of 25 kV 50 Hz electric locomotives built by Alstom and MTE between 1971 and 1978. Initially 65 locomotives strong, the series was widely used on the whole French 25 kV network before losing services to TGV trains when the LGV Est went into service in 2007.
The SNCF Class BB 7200 is a 1.5 kV DC electric locomotive operated by the SNCF in France. It is the DC version of the 'Nez Cassé' family of locomotives built between 1976 and 1985 by Alstom. They are rated for 4,040 kW (5,420 hp) of continuous power. SNCF Class BB 15000 is the AC version while the Class BB 22200 is a dual-voltage version. Another relative is the NS Class 1600 operated in the Netherlands, a DC locomotive based on the BB 7200. Intended primarily for passenger service, increasing numbers are being allocated for freight service with lower-geared bogies as passenger services are taken from locomotive-hauled coaches by TGV services. BB 7200 operations are limited to the French 1.5 kV DC electrified network in southeastern France, from Paris southwards. In 2016 48 were allocated to freight, 58 to intercity passenger service, 50 to regional passenger service, and two to auto-train service.
The SNCF class BB 20004 locomotive was a dual-voltage test-bed locomotive transformed from the damaged BB16540 in 1959. After the end of its test period in 1969 it was reinstated with its original equipment under its original number BB16540.
The SNCF Class BB 30000 electric locomotives were built by Fives-Lille, CEM and MTE in 1961. They were the tri-current version of BB 9400 "Vespa" locomotives, of which they were closely derived, and inherited much of the knowledge of the experiences of BB 20004.
The Class 13 are a type of mixed use 200 km/h (124 mph) multivoltage electric locomotive of type Traxis designed by Alstom in the late 1990s for the Belgian and Luxembourgish railways.
The SNCF Class BB 36000 locomotives are a class of triple voltage 4 axle twin bogie electric locomotives built by GEC-Alsthom between 1996 and 2001 for SNCF.
The Spoornet Class 14E of 1991 was a South African electric locomotive.
SNCF CC 70000 was a class of two prototype high power diesel-electric locomotives numbered CC 70001 and 70002. They were built at the same time as a diesel-hydraulic version, BB 69000.
A monomotor bogie is a form of traction bogie used for an electric locomotive or diesel-electric locomotive. It is distinguished by having a single traction motor on each bogie.
The SNCF CC 40100 was a French class of quad-voltage 4,340 kW (5,820 hp) electric locomotives. They were intended for high-performance passenger services on the Trans Europ Express (TEE) routes of the 1960s and 1970s. This non-stop international working required them to support the electrical standards of several networks. They are significant for combining three innovations in locomotive design: quad-voltage working, three-axle monomotor bogies and the new 'Nez Cassé' body style of French locomotives.
The BB 13000 class were electric locomotives operated by SNCF in France. They were one of four classes, together with the BB 12000, CC 14000 and CC 14100 classes, that formed an experimental group for studying the practicality of the new French 25 kV 50 Hz AC electrification.
The SNCF BB 9003 and BB 9004 are French direct current electric locomotives with two trucks each having two driving axles. Built at the same time as SNCF BB 9001–9002, these four units were used to evaluate locomotives with total adhesion in the course of normal operation. They also served as prototypes that helped define the mechanical and electrical characteristics of future locomotives to be ordered in greater quantities.
The BB 25150 is a class of electric locomotives in service with the French railways SNCF, built by Materiel de Traction Electrique (MTE) between 1967 and 1976. They are dual voltage locomotives working off both 1500 V DC and 25 kV 50 Hz AC. Designed by André Jacquemin, the class is a development of the earlier BB 25100.
The BB 25200 is a class of electric locomotives in service with the French railways SNCF, built by Materiel de Traction Electrique (MTE) between 1967 and 1976. They are dual voltage locomotives working off both 1500 V DC and 25 kV 50 Hz AC. Designed by André Jacquemin, the class is a development of the earlier BB 25100 and BB 25150 locomotives with a higher top speed, being capable of 160 km/h (99 mph). It is the dual voltage equivalent of the BB 9200 and BB 16000 classes.
The BB 20100 was a small class of two groups of two dual voltage electric locomotives of SNCF intended for cross-border traffic between France, Switzerland and Germany.
