Stone Box Culvert with Wing Walls

A cut-stone box culvert with a rectangular metal-lined opening and neatly coursed masonry, flanked by sloping wing walls that step down to grade with capstones along the top. The stonework shows realistic block joints and subtle weathering.

It slots under an embankment on a model railroad or road diorama to carry a stream or drainage channel beneath the fill, and works equally well as terrain detail on a wargame table representing an established period infrastructure.
