The Bachmann HO Scale Track King Train Set is an excellent entry into the hobby of model railroading. Headed by a powerful EMD GP40 locomotive decorated in Union Pacific's iconic Armour Yellow paint scheme, the Track King is ready to conquer any freight job it faces with the included tank car, boxcar, flatcar, and caboose, all with E-Z Mate(R) magnetic knuckle couplers. Set up your track, move freight, and start building your very own HO Scale railroading empire. Also includes a UL-listed power pack, speed controller and an illustrated instruction manual.
