Union Pacific Maintenance Machines Leave Siding in Ames, Iowa

On the morning of September 3, 2012 (Labor Day), I found a large Maintenance of Way (MoW) force getting ready to work on a tie replacement project on the Union Pacific in Ames, Iowa. In this video, many machines are seen leaving a siding, although a few are seen going in. Below is a list of equipment seen. It is arranged with the time of the video, the reporting mark (if know), which always begins with "UP," the maker of the equipment (if known), and the type of equipment (if known). Feel free to comment it you know any additional information. 0:00 UP CATS-1001 Prasser-American 9-16 DYNA-C.A.T.
