AHM 5098-02 Premium Production Run UP Class FEF-3 4-8-4 Northern Locomotive #836
The Union Pacific Railroad bought 45 4-8-4s in three orders from the American Locomotive Company.
The first order of 20 locomotives (road numbers 800 through 819) was delivered in 1937. These were designated Class FEF-1 (“FEF” stood for four-eight-four) “Northern” and were designed by UP's Motive Power Group to have 77" drivers, 24.5 x 32 cylinders, a boiler pressure of 300 psi, and a weight of 465,000 lbs. resulting in a tractive effort of 63,611 pounds (63,800 nominal).
The second order of 15 “Northerns” (road numbers 820 through 834) was delivered in 1939. These locomotives were designated as Class FEF-2. They were designed to have 80" drivers, 25 x 32 cylinders, a boiler pressure of 300 psi, and a weight of 483,000 lbs. giving each a tractive effort of 63,750 pounds (63,800 nominal).
The last group of 10, Class FEF-3 “Northerns” were delivered in 1944 and were assigned road numbers 835 through 844. These FEF-3s were very similar to the Class FEF-2's. The FEF-3 class represented the epitome of dual-service steam locomotive development
Built and designed in a joint effort between the Union Pacific and ALCO, the FEF-3 class could safely handle 120 mph. On one occasion, one of the engines of the FEF-3 class pulled a 1,000-ton passenger train at 100 mph. All FEF classes were considered by the Union Pacific to be capable of producing between 4,000 and 5,000 drawbar horsepower.
The last of the class, #844. never actually left service. Its 1957-1959 stint of freight work was its last revenue work. Saved from scrapping in 1960, #844 was chosen for rebuilding and is now used on company and public excursion trains, Today, it is one of UP's oldest serving locomotives as well as the only steam locomotive never retired by a North American Class I railroad.
From 1979 until their original demise in 1997, Rivarossi produced standard and extra highly detailed Premium Production Run versions of the Union Pacific FEF-3 4-8-4 Northern in six different road numbers. Road Number 836, like this AHM5098-02, was only produced between 1979 and 1983. Since AHM went belly up in the mid 1980's our super rare mint condition Premium Production Run AHM5098-02 was certainly produced during that window. Add our include MRRHQ Custom Directional Back-up Light, never offered by AHM, and our MRRHQ Exclusive Dual LED Operating Headlamps and it is very Premium indeed.
