The passenger lead is a railroad term referring to the main track into a station or passenger yard for passenger trains. From the passenger lead, the individual station tracks branch off to create a yard. This is of course a very basic description, rail yards in themselves are a maze of leads, branches, spurs, cutoffs, house tracks, run-arounds, mains, and sidings. Now after that; I was to pickup my friend and his fiancee from Denver Union Station after their trip on the Amtrak California Zephyr to Glenwood Springs. I was able to get out and make a couple shots off the side CO 72, but wasn’t able to catch them again until downtown Denver. Short trip, a couple shots, a nice little exercise to keep the photo muscles in shape.
