Union Pacific FEF (Four Eight Four), along with the GS-4 is easily one
of the most recognizable US steam prototypes still in operation today.
The FEF-3 series of steam locomotives was delivered in 1944 and were the
last, and some of the largest, steam locomotives delivered for use by
the Union Pacific. Operated solely by the Union Pacific, the FEF's
(sometimes referred to as "Northerns", due to the NP's being the first
to build steam locomotives with the 4-8-4 wheel arrangement) were
intended primarily to be passenger locomotives but the UP's large fleet
of available diesels meant that the FEF's were put to work in secondary
passenger and fast freight service.
The Kato N Scale FEF-3 follows in the footsteps of its Southern
Pacific 4-8-4 cousin, refining the basic concept of a high-power,
flexible steam locomotive which is easily upgradable to DCC by coupling a
special, isolated coreless motor drive system with heavy duty flywheels
and a flexible cross-braced suspension system that gives the locomotive
a high torque, high traction grip that ensures constant and consistent
pressure spread across the primary drivers. Another benefit of the
coreless motor system is that the locomotive will have an extremely low
starting voltage, giving the locomotive slow creeping speeds that will
allow modelers to appreciate the complex arrangement of moving side rods
that make steam operation so exciting. Other features, such as the
locomotive's unique "Centipede" style tender being fitted with special
articulation mechanisms that appear seamless when observed but will bend
and flex to allow the locomotive to navigate tighter corners than
should otherwise be possible!
- All black drivers and a dark graphite smokebox
- Semi-modern appearance is appropriate for modern layouts behind
UP Excursion trains as well as historical layouts operating freight and
UP passenger services.
- Coreless motor design with dual brass flywheels for silky-smooth performance at all speeds, even slow crawls.
Special cross-braced shock absorbers equalize the pressure on the locomotive drivers to maximize traction.
- Illuminated headlight and locomotive numberboards. The FEF tender
does not have operational lights, but lighting kits are available for
the special Water Tender cars (sold separately)
- 11" (282mm) Minimum turning radius on ground level track, 15" (381mm) Minimum turning radius on Viaduct track.
- All detail parts installed.
This locomotive has had TCS DCC Pre-installed by a technician at Kato USA for a true ready-to-run on DCC experience!. Note - DCC only, not sound
