No Cars On Track Sign
Cars aren’t allowed on the track! Probably more useful for tram track junctions than railroad or metro.
Low-poly, 128×128 textures, and shares a common specular map and mesh with my newer (and future) road sign assets if you use the Loading Screen Mod.
All my signs are props, so you need to use More Beautification mod to place them. They show up in the general props category (the park bench icon).
