Add authentic railway infrastructure to your HO layout or diorama with this detailed signal mast model. The piece features a long cylindrical steel pole, two stacked signal heads mounted on short cross-brackets with visible clamp plates, a round mid-shaft indicator disc, and a rectangular electrical junction box on the lower shaft. Supplied as a single HO 1:87 master STL (Miniature Reality ships one master file only); scale uniformly in your 3D software to print at other scales. The geometry is intentionally simplified in deep cavities to improve print success while preserving the silhouette and mounting detail modelers need for installation and painting. Ideal for model railroaders, diorama builders, and display modelers who need a rugged, paintable railway prop.

Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)

Ready to print digital download in one piece with no assembly needed.
