This special ''One Time'' run will be identical to the B Units in the A/B Sets but will not have a road number. A decal sheet of road numbers will be included as well as the ''Santa Fe'' wording (for later models). GENESIS premium line ready-to-run HO locomotives feature true-to-prototype body detail that includes full cab interior, true-to-prototype lettering, acetal plastic handrails and separate grab irons. Each locomotive features a new power chassis and drive system, and features constant/directional lighting, chemically blackened solid nickel-silver wheels, all wheel pickup and isolated can motor and motor mounts ready to accept your DCC circuit board.
