I just returned from a trip to North Platte, NE, to see the new Golden Spike Tower and Bailey Yard, but I also spent some time at the nearby Cody Park in North Platte. It is a nice park for family get-togethers (barbeque, grass, baseball, trees, etc.), but for railfans the attraction is the UP area. They have both a Challenger and a DD40X on display and they are both beautifully restored and available to checkout and photograph up close. I will attach a few of the many photos I took and hope you enjoy them. The first 3 photos are of the Challenger 3977 (that firebox is huge!), the forth is the DD40X 6922, the 5th is a close up of a standpipe by the locos (I am always looking for details for my layout) and the 6th is of the Bailey Yard Inspection Pit and Sanding area.
