All three shots are the same location (within 1000'). In the last pic you can see the remains of the depot platform. That's Orcutt Creek bridge in the passenger train pic and Wilawana Road (4022) is the crossing. The passenger train pic is a bit earlier I think, but Wilawana was long gone as a station stop so the wrong-main-thing was probably for track work or something else. The right of way through here is still there, although I think all traces of the platform are gone now too. Rte 17/I-86 is on the other side of the valley here, near the Erie. The road is still there but improved a bit. The hill in the right background of the second two pics ends at Nine-Mile bridge, which is where the DLW and now I-86 cross the Erie/NS.
What the #*** did we just hit, Over ???
