those train pushcart things? The ones where there is a person on each side pushing up and down on the lever thing. It moves down the track with human power. And if you can answer that, what mechanism is used to make it run?
This should help-

HAND CART…simple…
The mechanisim is the two guys pumping it. Up and Down, Up and Down, ETC. ETC. ETC. As always ENJOY.
The mechanism is similar to the piston rods and main rods on a steam locomotive, except that it is mounted vertically and two men instead of steam provide the energy to move the rods.
