I just received one of the newly released 1/20 scale Accucraft K-27 453s and was wondering about how the coupler would be attached to the pilot when the plow is attached. One would assume that there should be some sort of very strong connection between the pilot, back of the plow, and a coupler mounted on the plow so the whole deal would be strong enough to push trains / helper service. The model has no such device or support. Any help? Thanx, Gary
