I think I'd like to walk in from the creek as well....It appears that the creek has changed it's path greatly through the area...may not be much left. Also, most of the structure was wood, so there will be little remaining.
Here is the 2nd map that the Tonawanda Valley and Cuba narrow gauge filed with Cattaraugus County in June 1882. This is as close to the actual route as I can tell. I assume that the BA&A utilized the same route, only because they purchased parts of that property as far as Sandusky. The TV&C's original route filing in 1881 kept the tracks on the west side of the State Road, much more as the later B&S did through that section. It is a guess, but perhaps the TV&C chose the above route, closer to the creek due to cost of acquiring the property? They wouldn't have cut through any productive farm fields at that point. Not the best choice for a solid road bed though. The map shows the creek path fairly straight for a long stretch. The solid red lines are just the reference points for the curves for the profile part of the filing with the county. I made a dotted line to show the track location. Unfortunately the original maps on file are poor to begin with, so the photo copy doesn't show up that well.
This is a photograph of the wreck. The photographer is looking south towards Sandusky. You can see that the structure was very long and composed of wood. Given the length of the structure, the creek must have shifted or filled up quickly through that curve at times of high water. Compared to the pins on Chris's map, the route of the creek has changed significantly. You can also make out the concrete work of the abutment. Should anything be remaining in the creek today, it could be compared to this to see if it is a newer retaining wall of some kind.
I have copies of newspaper accounts of the wreck. My Great Grandfather, John Henry Connors was head end brakeman on that train. The engineer had called for brakes, so he was out ahead on the gravel cars setting brakes. Otherwise he would have been in the cab seated next to the fireman that passed away in the wreck. He only remembered waking up in the field next to the creek surround by locals. Shortly thereafter he changed careers as he had a young family and wished to stay alive for them. (He also had a close call with a plow derailment near the Knitting Mill previously).
