The Pacific-type locomotive evolved |
as the need for power and speed increased. First, the four-wheel
leading truck delivered stability at the faster speeds. Second,
six tall drivers provided pulling power and speed. Last, a
two-wheel trailing truck provided support for a larger firebox.
The sum of this design was the 4-6-2 USRA Pacific.
The USRA designation for light and heavy locomotives was a
function of the track's ability to withstand weight. Excessive
axle weight could damage the rails, loosen fastenings, and also
cause damage to the locomotive. The USRA deemed a maximum of
54,000 pounds per axle as a light locomotive. The USRA Light
Pacific weighed in at 277,000 lbs, with a 73 inch driver
diameter and a boiler pressure of 200 lb/in.
BLI's models follow the original designs closely. Railroad
specific variations are not modeled on these locomotives. In
most instances we offer two locomotive numbers for each
railroad, and we are offering a painted model (black) with no
NOTICE: Due to
insufficient boiler diameter in the USRA Heavy and Light
Pacifics, these units will not have smoke units.
