EN: Model of a prefab concrete box culvert. Culverts are very common around railroads and come in many varieties, shapes and sizes. See my other culvert products for headwalls and other types of culverts. In real life this would be 80"or 2000mm (scale 1:87).
NL: vierkante duiker. In het echt zou deze duiker 2000mm hoog zijn, inwendig, in schaal 1:87.
