This N-scale kit is the body only. You will need to add trucks, couplers, a brake wheel, ladders and catwalk mesh to complete. The model has been designed for BLMA 70-ton trucks and MT 1015/1016 couplers. The railings and other details are VERY fragile and may break off during printing or shipping. The model has been split at the color-change line to make painting easier. This kit is modeled in semi-transparent plastic and will require painting. Buying the multi-car models will save you some money per car. Versions are available that have 1, 2, 3 and 4 cars in them.
