Twenty five locomotives were built and the majority were used on UPs Wyoming Division hauling freight over the Wasatch mountains. The engine is 132 feet long (40.47m) including its tender, weighs 1,250,000 lbs (567,000 kg), with a power output around 6,290 hp. In 1941 the cost to build one Big Boy was $265,000 and in 2015 it has an estimated construction cost of $4,270,577 USD.

I've rebuilt most of my railroad fleet! To start us off I'm starting with my favourite steam engine the Union Pacific Big Boy, specifically 4014. This new version of the engine is 59 blocks long and 7.5 blocks tall. Compared to my previous version it is 1 block taller which makes this version closer to its proper height. The vast majority of the engines frame has been redesigned to better resemble the real engine and I'm trying a new way to design the rods on the driving wheels. There are plenty of ways this version resembles my previous version but there's more then enough changes that it feels like a new build. There's more engines to come as I've got plenty of new designs to showcase.
