USRA 4-6-2 Light Pacific, Vanderbilt Tender - Sound & DCC - Paragon3 -- Great Northern 1377 (Glacier Green, black, silver)

This HO Scale USRA Light 4-6-2 Pacific from Broadway Limited is based on standard WWI-era locomotives that delivered power and speed. 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 277,000lbs, with a 73" driver diameter and a boiler pressure of 200lb per inch. This detailed model features full Paragon3 sound and DCC for realistic sound an
