The 230 Nord 3.513 to 3.662 are mixed traffic 4-6-0 locomotives of the Compagnie des chemins de fer du Nord. On January 1, 1938 they became SNCF 230 D 1 to 149. Here are two 0 gauge models. A Nord version made by me from an LVDR/ACO kit and an SNCF version made by Fulgurex.
Locomotive 3.521 in Nord brown is made from a coarse scale 3-rail electric kit issued long ago by La Vie du Rail/Atelier du Château d’Eau.
Fulgurex made a number of versions of this 4-6-0 locomotive. Here I show the SNCF version of 230D18.
