Product description

Model: With digital decoder and extensive sound functions. Controlled high-efficiency propulsion. 8 axles powered. Traction tires. Equipped for two smoke generator 7226. The headlights change over with the direction of travel, number boards and smoke generator contact will work in conventional operation and can be controlled digitally. The cab lighting can be controlled digitally. Lighting with maintenance-free warm white light emitting diodes (LED). Curved articulated chassis. Boxpok wheels. Central coupling axles are sprung. Steam lines pivoted with the cylinders. Close coupling between the locomotive and the tender. Powerful loudspeaker in the tender, volume adjustable. Coupling hooks can be inserted into the rail scraper at the front. Attached metal handlebars. Many separately applied details. Figures of a train driver and stoker for the driver's cab are included. Length over the couplings approx. 46.5 cm.

The image is a digital retouch. Notes on operation: The locomotive can be used on curved tracks from a radius of 360 mm, but we recommend larger radii. Due to the overhang of the long boiler, signals, catenary masts, bridge railings, tunnel portals, etc. Maintain a sufficient distance to the curved track. For the heavy weight of the locomotive, the track must be firmly attached. The turntable and transfer platform can only be driven on in the drive-through position. Products bearing "Union Pacific" are made under trademark license from the Union Pacific Railroad Company.

You can find a freight car set to go with this in the Trix H0 assortment under item number 24914. You can find an AC version of this model in the Märklin H0 assortment under item number 37997.

One-time series.

 INFORMATION on Prototype                                               

The "Big Boys 4014" The series 4000 of the Union Pacific Railroad (UP) known as the "Big Boy" is certainly one of the most popular among the steam giants in America, if not worldwide. Initially 20 of these articulated locomotives (No. 4000-4019) of the type (2'D) D2'h4 were built in 1941 at ALCO from the continuation of the "Challenger" concept, extremely successful UP articulated steam locomotives of the type (2'C) C2'h4 . Another small series of five machines (No. 4020-4024) followed in 1944. The conception of the "Big Boys" resulted from the usual requirements as with all other American large locomotive designs: Fewer locomotives should transport heavier train loads at higher speeds. Basically, the UP procured the 25 machines for a single route: From Cheyenne / Wyoming 830 km westwards through the foothills of the Rocky Mountains over Sherman Hill to Ogden / Utah. The result was a gigantic machine for fast freight traffic with a service weight of 548 t (including tender). In July 1959, the Big Boy era was finally over and the fire in all machines went out. But on May 10, 2019, the 150th anniversary of the completion of the transcontinental railroad ("150 years of the Golden Spike") should be celebrated in style. After all, the UP was one of the two railways that had achieved this magnificent achievement. Therefore something spectacular should pay tribute to this event and so there were first rumours in 2013 that a "Big Boy" should be put back into operation. After all, there were still eight machines left. The UP steam locomotive specialists now checked each of the surviving locomotives in order to find the best candidate for remanufacturing. Ultimately, the choice fell on the 4014 in the Rail Giants Train Museum in Pomona, as the mild Californian climate had affected the locomotive the least and its boiler was in the best condition of all preserved machines. Their transfer to Cheyenne was finally completed on May 8, 2014 after a journey of several days. It soon became apparent that around 60% of the parts had to be replaced due to the decades of storage and the rest required a complete overhaul. The UP steam workshop with its nine employees originally planned five years to recondition the Big Boy. But during the same period a general inspection had to be carried out on the UP steam locomotive 844, so that the commissioning of the 4014 only took two and a half years. It was not until February 6, 2019 that an important milestone in its processing was successfully mastered. It passed the water pressure test of the boiler. Now it happened in quick succession. On April 9th, the 4014's oil burner was lit for the first time. But time was running out, because the locomotive was supposed to be seen under steam at a major event in Ogden on May 9th. So only a short test drive was scheduled for the 4014 on May 2nd, which was successfully completed. It is estimated that the UP had to spend at least four million US dollars on the processing. But from that day on, the railway company again ran the largest and most powerful operable steam locomotive in the world.
