Others have walked through the Posted No Trespassing zone, but I walked it from both directions respecting the signs. From Google Earth I didn't miss much. When I was up the grade from S Wye last which was since Jim drove it, there was a heck of a water bar/ tank trap across the grade at the forest boundary. Perhaps it could be driven around especially on an ATV. Going back to my original post, and the one with the maps, I have made corrections to both of those. DWJ has it right, the pile up was at MP 32, and the engineer lost control 1.25 miles above, not below MP32 which is at a 24 degree curve. Thanks DWJ!
