Prototype: Class A3 steam express locomotive with a tender. Version as museum locomotive 60103. The locomotive looks as it did in 1963 with a Corridor tender and smoke deflectors, thus as the locomotive currently looks operational and based at the National Railway Museum in York, England.

• Completely new tooling.
• Especially intricate metal construction.
• Many separately applied details.
• Factory-installed smoke unit with speed-dependent, dynamic smoke exhaust.
• Cab and tender corridor lighting digitally controlled.
• RailCom-capable digital decoder and extensive light and sound functions included.
• Buffer height on the locomotive and tender adheres to the NEM.

Model: The locomotive has an mfx+ digital decoder and extensive light and sound functions. It also has controlled, high-efficiency propulsion with a flywheel in the boiler. 3 axles powered. Traction tires. The locomotive and tender are constructed mostly of metal. The locomotive has a factory-installed smoke unit with speed-dependent, dynamic smoke exhaust and it can be controlled digitally. Dual headlights on the locomotive change over with the direction of travel and there is a lamp on the back of the tender. These lights will work in conventional operation and can be controlled digitally. The lamp on the back of the tender can be changed to a red lamp. A third headlight on the front of the locomotive can be controlled separately as an electric lamp and it can be changed to red. The cab lighting and firebox flickering can be controlled digitally. The lighting on the tender corridor can be controlled digitally. Maintenance-free warm white and red LEDs are used for the lighting. There is an adjustable close coupling with a guide mechanism between the locomotive and tender. The back of the tender has a close coupler with an NEM pocket and a guide mechanism. The buffer height on the locomotive and tender adheres to the NEM. Brake hoses, imitation prototype couplers, and closed cylinder covers are included. Length over the buffers approximately 24.5 cm / 9-5/8".
