Big Boy rebuild

Some trivia:

The 25 Big Boys were built by ALCO (American Locomotive Company) in two groups. The first group of twenty (10+10), 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. At 6PM on 5/9/1941, the first BigBoy, #4000, strode through the east end of the UP's Omaha yard. The last commercial freight pulled by a Big Boy was in July of 1959. 4006 had the highest mileage - 1,064,625 = 1,713,347 km.
