Gauge: H0 Era: III
Prototype:
Union Pacific Railroad (UP) class 4000
"Big Boy" heavy freight locomotive. Version with the road
number 4019 as equipped with smoke deflectors. In the winter
of 1944/45 this unit had smoke deflectors installed on it as
an experiment.
Model:
The locomotive has an mfx digital decoder and a sound generator. It also has controlled high-efficiency propulsion. 8 axles powered. Traction tires. The locomotive has an articulated frame enabling it to negotiate sharp curves. It also has Boxpok driving wheels. The middle driving axles are spring-loaded. The headlight, backup light on the tender, and the number board lights are maintenance-free, warm white LEDs. 2 smoke generators (7226) can be installed in the locomotive; the contacts for them are on constantly. The headlight, backup light on the tender, the number board lights, and the engineer's cab lighting will work in conventional operation and can be controlled digitally. There is a powerful speaker in the tender and the volume can be adjusted. Coupler hooks can be inserted in the pilot on the front of the locomotive. There is a close coupling between the locomotive and tender. Steam lines are mounted to swing out and back with the cylinders. The locomotive has separately applied metal grab irons. There are many separately applied details. Figures of a locomotive engineer and fireman for the engineer's cab are included. Length over the couplers 46.5 cm / 18-5/16". The locomotive comes in a wooden case.

Highlights:
- Unusual version with experimental smoke deflectors
(tested during winter of 1948/49).
- Detailed tooling changes to the locomotive and tender.
One-time series released in 2012.
Additional Information:
- The locomotive can be used on curved track with a radius of 360 mm / 14-3/16" or more, however
Märklin recommends larger radii. Due to the overhang of the long boiler, signals, catenary masts, bridge railings, tunnel portals, etc. must be installed for sufficient clearance on curves. The track must be well mounted due to the heavy weight of the locomotive. The locomotive can only be run through a turntable or transfer table.
