Z Scale SW1200 in Northern Pacific livery. This unit includes directional LED lights, MTL couplers, weathering, and a storage box. It is powered with a Rokuhan motor. Traction is provided by the rear truck. The front truck is free wheeled. This unit has been tweaked to run smooth and have good electrical pickup. It only has a single powered truck so short trains are recommended (6 to 12 cars with metal wheels is best).
