Union Pacific Big Boy (# 4014) DCC w/Sound (Special Hand-Weathered Edition) (Very Limited Run)

Sorry, this product is sold out and no longer available from the manufacturer.

Prototype: Union Pacific Railroad (UP) class 4000 "Big Boy" heavy freight locomotive. Version with the road number 4014, cooling pipes, and authentic weathering. The locomotive looks as it did around 1948.

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.

One-time series.

The Union Pacific Railroad (UP) class 4000 known as the "Big Boy" is surely one of the most popular steam giants in America if not worldwide. These articulated locomotives with their 4-8-8-4 wheel arrangement had their origin in 1941 at ALCO from the continuation of the "Challenger" concept, extremely successful UP articulated steam locomotives with a 4-6-6-4 wheel arrangement. The conception of the "Big Boys" resulted from the usual requirements as with all the other American classes of large locomotives. Fewer locomotives were expected to pull heavier loads at higher speeds. The UP bought the 25 units for only one single route: From Cheyenne, Wyoming 830 kilometers / 519 miles westwards through the foothills of the Rocky Mountains over Sherman Hill to Ogden, Utah. Before the pass named after General William T. Sherman is a long grade of about 50 kilometers / 31 miles from Cheyenne with a maximum climb of 1.5 percent. In the opposite direction, the 105 kilometer / 66 mile long grade of 1.14 % through the Wasatch Range of the Rocky Mountains demands it tribute. The result was a gigantic machine with a service weight of 548 tons (including the tender). An attempt was made to reach an equal distribution of the weight with the 4-8-8-4 wheel arrangement that had not been built up to then. With a grate area of almost 14 square meters / 150.70 square feet and a superheating surface of 229 square meters / 2,464 square feet, the Big Boys had a continuous power rating of 6,290 horsepower at the couplers. Boiler performance of over 10,000 horsepower or 8,200 electrical horsepower was recorded. The assigned range of duties for the "Big Boys" was fast freight service. They were capable of pulling 4,000-ton trains over the mountain passes without help. The new locomotive had a design speed of 128 km/h or 80 mph that it reached with only 1.7 meter / 66-15/16" diameter driving wheels. This put it in the ranks of the fastest articulated steam locomotives. However, these units were not allowed to thunder through this part of the West at this speed in regular service. Locomotive engineers confirmed, however that the speedometer often showed more than the allowed 112 km/h / 70 mph when they were running late. According to the legend, these giants acquired the nickname "Big Boy" from a young worker who scribbled the name on the smoke box shortly before the locomotive was presented. Officials from ALCO and UP liked this so much that "Big Boy" was even used in the advertising for the locomotive. On average, these units consumed 47,200 liters or 12,469 gallons of water and 22 tons of coal per hour. Of course, a fireman would have been overwhelmed if he had had to feed one of these ravenous beasts with a shovel. A stoker moved coal from the tender to the locomotive by means of a screw in a pipe and sprayed it into the firebox with steam pressure. The fireman adjusted the distribution of the coal in the firebox by controlling the steam pressure. In the fall of 1945, the UP decided to equip a "Big Boy" with smoke deflectors as an experiment in order to keep the smoke out of the engineer and fireman''s eyes. In the beginning of December 1945, the "Big Boy" with road number 4019 had smoke deflectors installed on it at the maintenance center in Green River, Wyoming. The tests were finished on January 20, 1946 and these "large ears" were removed again in Green River. The tests had shown that at lower speeds in freight service and with recently improved blowers, the smoke could be routed ever better over the engineer''s cab and without smoke deflectors. The Big Boy era was definitively past in July of 1959 when the fires in all of the units were banked for good. The hope of many railroad fans to see road numbers 4003 and 4019 (stored in operational condition as reserve locomotives in 1960) thundering one more time over Sherman Hill sadly did not happen. At least eight of the steam locomotive giants were preserved but not in operational condition.

The image of this model is a retouched digital image. Notes for operating this locomotive: The locomotive can be used on curved track with a radius of 360 mm / 14-3/16" or more, however we recommend 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.
