On a traditional steam locomotive the pistons drive the wheels directly via cranks. An unusual looking series of variants, the geared locomotives, took a different approach - using gears and driveshafts, giving them an advantage in traction at the cost of speed, making them ideal for steap grades and tight curves of logging railroads. The most common was the Shay Locomotive (video), with it's vertical pistons. Other variant included the Climax (video, seen at the Mount Rainier Scenic Railroad) and the Heisler, which had it's pistons in a V-formation (video). Many examples of the geared locomotive can be found at the Northwest Railway Museum.

Man who stopped train with his bare hands "was a longtime railroad man from an era when such boardings were routine.... Today, it is strictly against the rules -- sometimes a firing offense -- to step aboard moving locomotives or cars."
