Cheyenne's Big Boy Locomotive #4004 Reviews
Steam Locomotive at its best and biggest! May 13, 2010
If you are a Railroad buff, this one is for you. Located in Holiday Park, Cheyenne, Wyoming the 4004 Big Boy is one of only 8 of the surviving 4-8-8-4 Big Boy Locomotives still around. They were begun in the late 1930s to haul heavy loads by Union Pacific through the mountains of Wyoming. The 4-8-8-4 refers to the wheel configuration. Four leading wheels that turned with the curve of the rails, then 8 massive driver wheels, 8 more massive driver wheels, and then four small trailing wheels that also turned with the curve of the rails. And because of the large length of the double sets of driving wheels the tightest corner one of these could take was 20 degrees, which is a very large curve. The first one went into service on September 5, 1941 in Omaha, NE. These were the largest of the successful steam locomotives. All together there were 25 built and they served well for twenty years, logging an average of about one million miles each. The last one was retired in July 1962. This one still displays well, even if some of the minor things have been removed or worn out.
The others are on display at the following locations:
4014 – Pomoma, CA. – L.A. County Fair Grounds
4005 – Denver, CO. - Forney Transportation Museum
4006 – St Louis, MO – Museum of Transportation
