Model: With a digital decoder, controlled high-efficiency propulsion, sound effects generator, and auxiliary functions. High efficiency motor with bell-shaped armature and fly-wheel in the boiler. 8 powered axles. 4 traction tires. Articulated frame allows the locomotive to negotiate sharp curves. Boxpok wheels. Middle driving axles with spring suspension. Headlight, tender, and number boards illuminated with maintenance-free LED's. 2 smoke generators (Seuthe no. 11), can be retrofitted, contacts are always ready for operation. Headlights, number boards, and engineer's cab lighting will work in conventional operation and can be controlled digitally. Speeddependent steam locomotive sound effects, bell sound, whistle signal, squealing brakes, as well as acceleration and braking delay can be digitally controlled with the 6021 Control Unit or with the 60652 Mobile Station. Additional operating sound effects can be digitally controlled with the 60212 Central Station. Efficient speaker in the tender, adjustable volume. Coupler hooks at both ends can be inserted in the rail guard. Close coupling between locomotive and tender. Steam lines are hinge-mounted with the cylinders. Separately applied metal grab irons. Many separately applied details. Figures of a locomotive engineer and fireman for the engineer's cab are included. Length over couplings 46.5 cm / 18-5/16".

The 37991 locomotive in the version presented is manufactured as a one-time series for Insider members.

Product info

Operating Instructions: The locomotive can be used on curved tracks with a radius greater than 360 mm / 14-3/16", however we recommend larger radii. Signals, catenary mast, bridge rails, tunnel portals etc. must maintain sufficient clearance to the curved track. The track must be stably mounted due to the heavy weight of the locomotive. Turntable and transfer table can only be used in transit position.

Prototype information

The 25 class 4000 machines are considered to the world"s largest series production steam locomotives. In this regard the nickname "Big Boy", which was even used officially, is rather modest. The approximately 40 m / 131 feet giants produced a power output of over 6,200 Hp with four huge cylinders. Accordingly the acoustic backdrop that accompanied such a monster was particularly imposing. With the new sound effects circuit, the H0 model produces the typical sound of the huge steam engine in...

The 25 class 4000 machines are considered to the world"s largest series production steam locomotives. In this regard the nickname "Big Boy", which was even used officially, is rather modest. The approximately 40 m / 131 feet giants produced a power output of over 6,200 Hp with four huge cylinders. Accordingly the acoustic backdrop that accompanied such a monster was particularly imposing. With the new sound effects circuit, the H0 model produces the typical sound of the huge steam engine in operation, as well as a selection of auxiliary sounds which can be triggered individually. The full range of acoustic functions is available when the locomotive is operated with the Central Station from the Märklin Systems program.
