Bachmann HO 6641
Union Pacific 4-8-4 FEF-3 Steam Loco #843
w/DCC/Paragon 4 Sound
This Broadway Limited HO Scale UP Class FEF-3 4-8-4 is based on the 10 Northern Type engines built by Alco Schenectady Works in December 1944. Class FEF-3s #835-844 featured larger 14-wheel centipede style tenders with a 23,500 gallon capacity tenders than predecessor FEF-1s and the same as the earlier FEF-2 Northenrs. FEF-3s were equipped with low-backpressure double stacks and developed 63,800lbs of tractive effort.
Throughout their service careers multiple modifications were made, including conversion to oil, feedwater heater systems, addition of smoke lifters (designated Wind Wings on UP drawings) and a Mars light, and replacement of stacks from singles to doubles and even triple stacks. UP 844, the final steam locomotive delivered to UP, has been in continuous service on Union Pacific since it was built in 1944; renumbered from UP 844 to UP 8444 between June 1962 and June 1989. This HO Scale Class FEF-3 4-8-4 features full Paragon4 sound and DCC for realistic sound and motor control complete with back EMF for smooth slow speeds. The Paragon4 sound system works with all Broadway Limited Rolling Thunder(TM) advanced sound systems. Other features include a heavy die cast body and chassis; smooth-running drive, applied details; directional warm white LED lighting and magnetic knuckle couplers. The FEF-3 can be operated on all DCC systems as well as on standard DC railroads (with limited sound functionality). This model has wheels profiled to operate on Code 70 and larger rail and curves of 18" radius or larger are recommended.
