‘Big Boy’ Heading Home To Cheyenne
After a successful run to Ogden, Utah, Big Boy #4014 & UP #844 are seen heading back to Cheyenne, Wyoming.
Only 25 UP Big Boys were manufactured between 1941-1944Advertisement
Big Boys were primarily used in Union Pacific’s Wyoming division, and could be seen running between Utah and Wyoming!
During World War II, since metal and fuel was in short supply, the Big Boy class locomotive was conceived to eliminate the need to double head up the Wasatch Mountains. UP originally ordered 20 class 4000 engines in 1941 and then 5 more in 1944 at $265,174 per engine. Adjusted for inflation, it is estimated that this would have totaled a whopping $107,620,056 or more in today’s dollars, each engine individually running $4,304,802!
While no one knows for certain, it is said that an ALCO employee had chalked the name onto the first 4000 class engine constructed.
Wasatch had initially been its planned name, but Big Boy stuck around!
