SNCF Class BB 7200
The BB 7200 is a French electric locomotive class for use on the DC network SNCF with 1.5 kV. The locomotives were built by Alsthom in the years 1976 to 1985.
The locomotives have the typical French locomotives of the 1960s and 1970s front shape of the designer Paul Arzens, the nez casse ( " broken nose " ) is called. It was first realized in the machines of the series 40100 CC and was also used for the sister locomotives BB 7200, the Wechselstromloks BB 15000 series and the Zweisystemloks the BB 22200 series applies. From the locomotive with number 7236 the front window in favor of a more spacious cab was performed less steep.
Construction
The BB 7200 were derived from the prototype machine BB 7003 and were the first Gleichstromloks with automatic load control. In addition, they are the last defense from the SNCF Gleichstromloks.
As a multi-purpose locomotives BB 7200 are able to carry both heavy freight trains and fast passenger trains. One of the vehicles was carried out for the freight service with lower translation certified for 100 km / h some of the vehicles was carried out for the passenger train service with high translation and approved for 160 km / h. In recent years, three locomotives were fitted with new bogies single BB 22200 for a maximum speed of 200 km / hr. Other BB 7200 have since April 2007 shuttle train.
Use
With its commissioning in 1976, the BB 7200 were initially assigned to the depot Villeneuve Saint -Georges. Since then, its area of operations has steadily expanded and so the locomotives are now practically on the entire DC network SNCF prior express and regional trains as well as to watch freight trains.
The main field of freight locomotives is today represents the line over the Mont Cenis between France and Italy via Modane
The locomotives for passenger trains are mainly used in passenger traffic in southwest France, including the 200-km/h-Maschinen carrying mainly trains the relation Paris -Toulouse.
The BB 7200 with push-pull train are used in front of the double-deck trains between Paris and Laroche, where they have the BB 9700 series displaced from these services. As of 2008, the new TER - pull trains of the Paris- Dijon -Lyon should be covered with BB 7200.
With the breakdown of the SNCF in various business areas, the stock of BB 7200 on 1 January 1999 was divided: VFE ( long-distance ), CIC ( via regional passenger ), Fret ( freight) and TER ( regional trains ).
Since 2012, 14 locomotives come on the Transilien Paris -Montparnasse ( line N ) before Voiture de banlieue à deux niveaux used. To this end, they are now referred to as BB 7600. They were designed to carry passengers upgraded (1.5 kV heating cables, push-pull train ) and have received a new paint job in Transilien style.
Coloring
For delivery all locomotives BB 7200 series in the then current " Concrete " livery were ( gray with orange colored ornamental line) painted. With the affiliation to the different business units of SNCF, this has changed. The following machines were repainted with as of May 2013:
