Motorized Union Pacific SD40-2 and Cooling Wagon

The buffer plow is usually attached to the machine, in this case the model is like this, I have decided to modify the system and generate the capacity of a better turn to respect to the length of the model, if we add the flexible coupling of the sleeves of brake, the strength is greater
