The Y 7400 class of small shunters is France's most numerous with 488 locomotives in the production build. The first 120 were built by Deauville, with further batches built by De Dietrich (105) and Moyse (263). They have the 0-4-0 ("B") wheel arrangement, 150 kW diesel engines and mechanical transmission. They can be found all over the French network.

During 1959 Y 7192 was converted to mechanical transmission and renumbered as Y 7001. This locomotive was the prototype for the Y7400 class.

Non-SNCF users

RATP have two Y 7400 class locomotives built in 1969 by Moyse. They are numbered T 102 & T 103 and were not part of the SNCF fleet.[2] Likewise Voies Ferrées Locales et Industrials (VLFI Transclusion error: {{En}} is only for use in File namespace. Use {{langx|en}} or {{in lang|en}} instead.) have two Y 7400 locomotives, 088 & 089, which were originally built for CFD. VFLI have augmented their fleet with Y 7474 and Y 7684 purchased from SNCF.[2]

Only Y 7566 has been preserved. It's based at Chemins de Fer de Blaise-et-Der, Wassy.[2]
