when i rode the bald knob train years ago (I think it was 1989 or 1990) I remember we met a whitaker train coming down at one of the switch backs. I think it was the lower because the engine (heisler 6) was at the tail end of the train coming down. Shays 2 and 5 were our motive power and pushed our train all the way to the end and then the whitaker train followed behind us into the tail section of the switch back. The whitaker train then continued down to cass and we went on our way to whitaker and bald knob. Pretty interesting move and well coordinated. I sat in the car right in front of shay 2. It was a soul moving experience listening to that shay push us up the grade.
