N Scale New Haven Budd 'Roger Williams' RDC Train Cab End body shell. Shell fits and clips to Kato RDC mechanism with some modification to the mechanism. We are planning underbody and nonpowered trucks for this shell to allow modelers to make nonpowered trailers or display models. The Midtrain unit is available for sale elsewhere on our Shapeways shop. The IHP 'Roger Williams' model was developed with the generous assistance of Mr. Jim Gagliardi of the Budd RDC Foundation and current owner of the surviving prototype 'Roger Williams' cars.
