Freight Locomotive BB 475000
for French National Railways SNCF

In February 2004, state-owned French National Railways SNCF placed an order for the supply of 400 diesel locomotives of the type BB 475000 with a consortium consisting of Alstom Transport SA (consortium leader) and Siemens. The order includes an option for an additional 100 locomotives. Siemens is supplying the traction equipment and control systems and building 130 bodies of the fixed batch in its Munich plant. This project is the largest single order placed by a European railway company in 30 years for the procurement of diesel locomotives.

Technical features

The design of the new BB 475000 diesel locomotive for SNCF reflects especially the expertise of the two consortium partners that has been demonstrated with the following locomotives:

  • the Rh 2016 diesel-electric locomotive built by Siemens AG for Austrian Federal Railways (ÖBB)

  • the BB 427000 electric locomotive built by Alstom Transport SA for SNCF

Mechanical parts and bogies are taken from the electric locomotive of the type BB 427000 and combined with components of the Rh 2016 diesel locomotive, including the electrical block, the diesel engine (MTU 16V 4000 R41), the cooling system, the braking resistor, the control system and the cab displays from Siemens.


The use of advanced and proven traction components based on the Rh 2016 for ÖBB, combined with the structural part of the BB 427000 from Alstom, was instrumental in SNCF’s purchasing decision. This combination is a perfect match for the specific requirements of the customer SNCF (optimized maintenance and spare part management, ease of operation for the driver, etc.). The BB 475000 will replace diesel locomotive series from the years 1960 to 1970 of SNCF and ensure freight traffic within the regional zones.
