Big Boy 4011
Title:  Big Boy 4011
Description:  UP 4011 has just topped off with coal and water in Rawlins on Halloween Eve, 1956. 4011 will be scrapped on June 14, 1963, the last Big Boy scrapped. By that point, only 8 remained, and, thankfully, they have all been saved, including 4014, which as since been returned to active service.
