SNCF Class BB 69400

The SNCF BB 69400 are a class of diesel locomotives resulting from the renovation and re-engining of members of class BB 66400 between 2004 and 2005 for the freight sector, Fret, of SNCF.

Rebuilding
The original MGO V16BSHR engines were replaced with MTU 12V 4000 R41 units. The re-engineering of the BB 69400 was an opportunity to review the ergonomics of the driving stations with the integration of standardized equipment and soundproofing of the cabin. Cabin air conditioning was installed utilising a 7.80 kW Soprano unit.

Livery
In addition to the Fret livery worn by these locomotives since their conversion, the BB 69400 allocated to the infrastructure sector, Infra, since 2015, have been repainted in the latter's yellow and grey livery.
