Reading through this old thread brought a memory to mind....which I humbly submit for consideration as winner in the foolish idiot department--though I plead youthful ignorance as an insanity defense, I was of driving age and certainly old enough to know better.
Did you know that an M37 will fit neatly on standard US tracks? By testing and experimentation, I discovered that if the tires are a bit deflated, one can take his hands off the wheel, and the truck will track just fine. I wonder to this day if the truck width is purpose-built or merely a coincidence.
It was near Malvern, Arkansas in 1973 at the Etta crossing. Fortunately, even though it was a busy line, I did not encounter a train. After traveling only about a quarter mile, I chickened out and never tried it again. Afterwards, I wondered what I would have done if I had seen the far away light from a train engine. If I had not been at a crossing, it could have been a problem attempting to cross the rails sideways/parallel and then what? Crash down the embankment? Rollover? Sideswipe collision?
And, no, I never told Mom.
