Berkshire / Kanawha 2-8-4
Nickel Plate Road
The North American Locomotive Works Nickel
Plate Road Berkshire is a S-2 modeled from plans from the Steam
Locomotive Cyclopedia Volume 1, published by Kalmbach Publishing.
This model represents a perfect balance of functionality and aesthetics.
Even sitting still in a rail yard the locomotive's appearance screams
power and capability. This superb model boasts many impressive features,
starting with a detail-rich 3D model, with fully animated Baker Valve
gear. multiple sound sets (including sounds sampled from S-2 Berkshire
759), multiple consists (including a special NKP consist), and a unique
custom cab by the very talented Rick Grout.
As an NALW first, we have included user-selectable
extras accessible through the installer. Select what options you would
like to install, and you're ready to run, without having to worry about
moving, copying, renaming or editing. If you own the Train
Artisan RS11 pack, you can install the included NKP Berkshire coal
train consist with a simple click of the mouse. Also included is an
installer-selectable choice between a natural sampled whistle from a
NPR 700-class locomotive, or a specially-created synthesized whistle.
The Berkshire / Kanawha 2-8-4 class of locomotive heralded in a new
era of steam locomotive. These engines were the first of the "super
power" locomotives typified by several features the most visible
being the 2 axle trailing truck with outside bearings which allowed
the locomotive's designers the ability to greatly increase the firebox
size. The first Berkshire was built by Lima Locomotive Works in 1925
as an experimental H-10 Mikado, in an effort to improve that types speed,
horsepower, and endurance. This first 2-8-4 was tested in the Berkshire
Hills on the Boston and Albany Railroad, and after its very successful
trials, the railroad bought 45 locomotives and the type became known
by the Berkshire name. By the end of the steam era, 610 2-8-4 locomotives
had been produced. Of that number, 20 exist today, including 6 Nickel
Plate Road S class machines.
The New York, Chicago
& St. Louis Railroad acquired its first 15 Berkshire class locomotives
from Lima in 1934. This design, the S class, was the result of much
internal study by the railroad and would eventually number 80 individual
locomotives, with 75 built by Lima and 15 built by Alco. These locomotives
were numbered 700 - 779.

Model Builder's Notes:
When Rick Grout first saw my early posts of
the Berk, he contacted me and offered his services to make a cab like
he had done for his "Aso Boy" locomotive. How could I refuse?
Rick's rendition of the Berkshire cab is fantastic and very accurate
