Ah, now here is the dirty, filthy SP we all knew and loved. SDP45 3200 leads "Popsicle" SD45 7399 on a westbound, if you can see it through the dirt! K64, Minolta X-700, Sigma 80-200mm f3.9
An interesting GP35, GP9, RS11, GP18 lash up, about to cross the B&O at Fostoria. N&W 1303 was later Springfield Terminal 214. Kodachrome 64, Yashica TL Electro-X
