Interactive silica unloading industry track with smoke and sound effects to be used with silica using industries or other structures that were not designed to be interactive or are just scenery only. This 21-1/2 meter long track will unload loaded hoppers and other similar bulk loading cars when moving over the track at 5KPH/3MPH or less. A short red and white striped marker pole indicates where the unload point is located. Height adjustable. The default track will be replaced by whatever track you attach to it. The red placement arrows will only show up in Surveyor mode. Based on an original Ben Dorsey (AKA bendorsey) content item. Meshes by MSGSapper. Reskin by Dave Snow. Thankx to Bob for allowing modifications to his assets.
