Bowser - HO - Steam Loco Kits
USRA Light Pacific 4-6-2



History:  If the weight on a single axle is too great for the track, the rail can be damaged. It is for this very reason that the USRA locomotives were designed in light and heavy versions.

The light pacific locomotives had only 54,000 pound load per axle, which allowed the light engines to run on most main lines. Light Pacifics had 25" by 28" cylinders, 73" drivers, and 200 pounds of pressure. The original models weighed 277,000 pounds and could carry 40,700 pounds. It cost $58,146.

Only 81 light engines were built and delivered in 1919. The B&O (45 locos), ACL (75 locos), GTW M&O (GM&O) and L&N were the three railroads that received these engines.

The Kit Includes:  Over 60 brass "Super Detail" parts.  In addition, the boiler & tender body have been pre-drilled to enable installation of all of the "Super Detail" parts.  No soldering is required.  All supderdetail parts may be glued to the zinc casting using your favorite glue (ACC, Goo, Ambroid, 2 part epoxy, etc.).
