The Last of Steam Power

Looking at the drive wheel of a Union Pacific Bug Boy engine, one might find it hard to understand how a small driver could produce such power. the drive wheels were small, not like the large ones on passenger locomotives. those produced speed. These had POWER, pulling power. they were configured as 4-8-8-4 and they were articulated so they could manage tighter curves. Not tight curves but tighter curves. These engines hauled freight out west where the tracks were straighter and could pull the higher grades found in the mountains; when necessary, they double headed pulling long consists. Manufactured by ALCO these were the most powerful locomotives ever made.
One of the most disturbing things is this museum is run by the Federal Government and is not well maintained. 4012 looked like it was painted with a 4″ house brush.

About Vermont Woodchuck

Professional Photojournalist since 1969 with a BFA from SUNY Purchase 1979-Visual Arts. I despise advocacy news journalism. Every photojournalist should be prepared to show their camera RAW images of news events. Reason: RAW images cannot be altered no matter what is done to the finished product.
