History and design

The locomotives were developed by SNCF for shunting duties. Initial construction was by Locotracteurs Gaston Moyse until that company ceased business, then by Fauvet Girel.[2]

Y 8000 machines were used to replace older shunting engines, as well as trip work on minor lines.[3]

The locomotives were 2 axle machines with both axles powered by a Poyaud (SSCM) diesel engine via a Voith hydraulic transmission. Locomotives were later re-engined (1997) with lower emission RVI engines; when re-engined locomotives received the green SNCF Fret livery.[1][2][3]

The locomotives also are certified for use in Italy, limited to shunting work:[1] Y 8120 has been operated by SNCF subsidiary CapTrain Italia.[4]

After 1989 production shifted to a mechanically identical Y 8400 type, which incorporated a radio control system for shunting.
