"The largest and most magnificent steam locomotives ever built! They were built to pull large tonnage over the 1.55%
continuous grade up Sherman Hill between Cheyenne and Laramie Wyoming . Before BigBoy, a helper service was required." They can do up to 80 MPH, but produce maximum continuous power at 70 MPH. - Jonathan Landon
"The 25 Big Boys were built in two groups. The first group, called "class 1", were built starting in 1941. They were numbered 4000-4019. The second group, "class 2", were built in 1944. They were numbered 4020-4024. The last revenue freight pulled by a Big Boy was in July of 1959. Most were retired in 1961. The last one was retired in July of 1962. As late as September, 1962, there were still four operational Big Boys at Green River, WY." - Wes Barris
