I know we have somewhere around 400 or so in the fleet, ranging from the SD59 to the SD62, all falling under the SD60 family. How many are in service? Not many. I've seen 3 and worked on 1 in the 2 years I've been with the UP. I wish I could disclose the location of where they're stored, but I can't. All I can tell you is how many we own.
