HO Scale 16th BOX Diorama Cliff Railway & Lower Road With Transparent Cover A joiner is inserted into the rail as a buffer stop. It can be slid left and right, so you can adjust it to your preferred location, and it can also be removed from the end of the rail. (The rails are new and unused.) Also, I think it can be used as a base for additional processing. This is a one-of-a-kind item made by an amateur. Please purchase with your understanding and agreement. Please check the condition in the photos. The passenger car in the photo is a sample and is not included in the product. The price is fixed. Clean-style diorama (Without weathering)
