A historical railway communication device, adapted for diverse creative projects and game environments beyond purely 19th-century settings. The term "highballing" (going at full speed) originated from this mechanism. The structure is fully modular: the main mast, all four pulleys, ropes, and both signal balls with their attachment rings are separated into individual meshes. This allows for easy animation of the signaling mechanics or independent use of parts. Optimized with PBR textures for weathered wood and rusted metal.
