The first shot is an eastbound rack train (I left my notes at home so I don't know the symbol) crossing the Magnolia bridge. Nikon N80, 28-80mm f/3.3-5.6 AF-G Zoom-Nikkor, Fuji Provia 100F.
The next shot is another eastbound, this time L296 This train runs from Flint, Michigan to Maryland carrying what must be high-priority auto parts. Every time we saw this train it had a pair of six-axle units and no more than twelve auto parts cars. In western Ohio I see this train and it has the same auto parts, but also a block of junk on the rear. Although I don't know exactly where, it must set out the junk somewhere enroute, most likely Willard or New Castle. Nikon N80, 28-80mm f/3.3-5.6 AF-G Zoom-Nikkor, Fuji Provia 100F.
The third shot is a westbound, probably Q416, coming out of Stuart Tunnel. N80, 75-300mm f/4.5-5.6 AF Zoom-Nikkor, Fuji Provia 100F.
The last shot is Q217, a westbound auto rack train, splitting the intermediate signals. N80, 70-210mm f/4-5.6 AF Zoom-Nikkor, Fuji Provia 100F.
