With the model 3066 Märklin, the German manufacturer of miniature trains, founded in 1859, reproduced the 204 (formerly 202) diesel locomotive of the Société Nationale des Chemins de Fer Belges (SNCB).
The real locomotive had been built by the AFB company under licence from the Swedish company NoHAB, now a subsidiary of General Motors. These locomotives, built from 1955, reached a top speed of 140 km/h. The trains were known as the gros nez (big nose) because of their frontal appearance. The SNCB assigned these locomotives to international passenger and light goods transport between Cologne and Paris and they continued to be operational until the 2000s.
