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 Decauville, 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.
