Amtrak's California Zephyr winds her way through the Rocky Mountains on the Union Pacific's Moffat Tunnel subdivision for a quick stop at Granby, Colorado. The GE Genesis P42DC locomotive 76 was built in 1997, while P42DC unit 159 was built in 2001. Both will eventually be replaced by Siemens Chargers on this run from Emeryville, California to Chicago, Illinois. #trainspotting #diesel
