It's a hot summer day in 1972, and Monongahela 1205 and 1216, 2000, and a wooden caboose sit next to each other outside what looks to be the old roundhouse as there is a turntable visible also.
Two things make this stand out in my memory. This is a Kodachrome in 1972, and that year I used Agfachrome almost exclusively. Secondly, the horn on my car wouldn't work properly until a friend hooked it up to a telegraph key, so I could still use it for this trip.
