 type made by Alstom.

The initial order was for 400 machines to be delivered from 2007 onwards with an option for a further 100 additional machines. The order is valued at 1 billion euros.

Background

The order for the BB 75000 resulted from a long and arduous project of renewal of diesel freight locomotives, which began in 2000, and spans a period of seven years from the announcement of the tender to the delivery of the new BB 75000s.

SNCF had a requirement for new diesel locomotives for two reasons:
  • The current diesel fleet is very old and expensive in terms of operation and maintenance.
  • The changes in European pollution and emission regulations as well as noise regulations make it necessary for the organisation to renew its fleet.

Tenders

The first document released by SNCF relating to this order was published in November 2000. It refers to delivery of 124 diesel powered freight locomotives and invites manufacturers to submit tenders. With a delivery date between 2003 and 2006 it set out a requiredment for two types of locomotives:
  • 55 Single cab locomotives with an average power of 1200 to 1800 kW (with performances comparable to those of BB 66000 and BB 67000) suitable for medium distance routes.
  • 69 High-power devices with two cabs for long distance trains. These locomotives would be expected to replace CC 72000 and would need between 2250 and 3200 kW of power.

However the project did not receive sufficient funding for the cost of the expensive high powered CoCo locomotives that would fulfill the second role and as a result the project was cancelled.

A few months after the cancellation of the first tender, a second was launched. It is based on the idea of a single multipurpose engine of medium power (1800 kW) similar to designs already available. These units would be used in multiple when necessary to provide a lower cost alternative to the expense of designing a high powered 6 axle from scratch. New tenders were to be delivered by November 2001 and technical meetings with potential manufacturers held during the spring of 2002.

In November 2002, Alstom and Siemens formed a winning consortium (with Alstom taking the lead role) and the project was finalized with SNCF in 2003. The contract was signed on 27 February 2004, and was substantially different from the original specifications published in 2000— not 124 but 400 new machines (all of medium power), which will reduce the average age of the locomotive freight fleet to 15 – 20 years.

The design used already proven components; traction components similar to those in the Siemens built OBB Rh 2016 and the structural design from the Alstom Prima 427000 series of locomotives.

Testing and approval

The first locomotives came off the assembly line at Alstom in Belfort in spring 2006. The BB 75001 and 75002 were sent to Test- and Validationcenter Wegberg-Wildenrath

. In February 2007 the order allowing entry into commercial operation was given by the Établissement public de sécurité ferroviaire (EPSF) and issued to Fret SNCF on the 27th of March.

Service

Following the test and approval process the production of the locomotives could begin; by the end of June 2007 thirty locomotives had been built.

). Workings in the East and South-East of France will be served by the later production models, while the West will be supported by the new type of BB 60000 and the BB 69000 (which are remotorised BB 66000s).

On 28 March 2007, the first commercial multiple working took place consisting of BB 75009 and 75006.

Conclusion

The introduction of this new locomotive should mean the elimination of BB 67,300, CC 72000, and through multiple unit workings of non-updated BB 66000.

It is not impossible that a variant be built or modified for passenger traffic (like the BB 27300 Transilien (derived from the BB 27000) because they have the necessary equipment

Updates

European standards will become increasingly demanding in terms of the requirements for particulate emissions and also the amount of CO2 emitted. These new guidelines will be implemented in two stages, taking place in January 2009 and in January 2012.

To comply with the first set of standards (Jan 2009) all new locomotives of this type will be built with a new diesel engine: the MTU 4000 R43. As well as engine modifications, the locomotive's exhaust will be changed (many locomotive manufacturers are implementing new exhaust systems to reduce emitted particulates). This will change the external appearance of these locomotives. All new locomotives built thus will be numbered from 200 onwards, i.e., BB 475200 and upwards in number.

In summary:
  • 75001 - 75006 Locomotives used for testing
  • 75100 - 75199 Machines fitted with equipment making them operable within Germany and the Benelux countries
  • 75200 - 75299 Machines with MTU engine 4000 R 43 and modified exhaust to meet 2009 emissions legislation
