well, EBarnacle, that wouldn't have been a train but a threshing machine. Though as you point out, it also used a steam engine. There are lots of songs about courting at the hay-making. (the steam engine really could be the making of future generations) As with Uncle Dave, I think you should have clicked at the link to the discussion thread and added your message there. The DTStudy thread should be kept shorter and include the more concrete background information.
