"Home, home on the range....Where the deer and the antelope play..."
On the morning of Wednesday, June 22, 1988, David DeVault and I were pacing this Wyoming & Colorado train south of Laramie, WY when I noticed an antelope trying to outrun it. For a couple of miles, he was ahead of the F-units, but then he gave up the race.
Edit (to answer Mitch's question in Comments): Here's a short answer: Back in the '80s, Dale Sanders, Mark Hemphill and Tom Taylor purchased a few former Alaska Railroad F-units, including these two (an FP7 and an F7B). They repainted these and lettered them "Mountain Diesel"---short for Mountain Diesel Transport (Dale, Mark and Tom). These two units were leased to the Wyoming & Colorado RR, which operated a former UP branch south from Laramie to Walden, Colorado. It didn't last long, however, and after the traffic base finally evaporated, the line was abandoned. I'm not sure what happened to these units. We had a number of friends and contacts back then with both the railroad (plus Dale, Mark and Tom, although they weren't involved with us riding the train), and we chased part of the way, and rode the cab part of the way (I chased--as I was doing here---and then we swapped out about halfway to Walden and I rode). Lots of great memories, and many excellent shots from the trip.
