Casco posted:Charlie, thanks for taking the time to provide your very thorough explanation. I think I get it now but I'll find out if that's true when I actually build the turntable and roundhouse.
As far as the rotational power for the turntable, I suppose horses or other draft animals could have been used as well. Modeling that would be pretty interesting.
Tom, that's a cool picture of man-handling a locomotive. It seems like it would take a lot more men than just one with a lever to move it. I imagined a bunch of guys climbing down into the pit and pushing the TT.

You don't need a team of horses or men to manually turn a steam engine. One man can easily do the job.
