This really nice HOe gauge loco by Roco is 04150 a Feldbahn narrow gauge diesel loco.
A Feldbahn, or Lorenbahn, is the German term for a narrow-gauge field railway, usually not open to the public, which in its simplest form provides for the transportation of agricultural, forestry (Waldbahn) and industrial raw materials such as wood, peat, stone, earth and sand.
The loco is in excellent condition as you can see in the pictures, the loco is tested and runs, and the overall condition is very good. It comes complete with its box. The box is in good if slightly shelf worn condition.
Overall this is a really nice scale locomotive and would look fantastic on a layout.
Do please have a look at my other listings, I typically have various HO and OO locos on offer as well as an extensive range of imported N gauge locos and other items.
Note: I do recommend all locos are cleaned & serviced, as they have some age to them even if the quality looks at the highest level (fairly standard advice for all locos!).
