Shuttle a lot of rail cars by hand?
You got it :)
Was kidding...when I was about 10-12 years old I was always working on snowmobiles etc, I really did not know what I was doing, but somehow used to keep 1 going.
Old farmer neighbour used to rib me , he would say the same thing every day, check to see if the pin has fallen out of the johnston bar
To this day I never knew what it was, I guess it was part of a train as you say.
Thanks :)
