Larry,
The passenger cars were part of the excursion trips that the I&O used to run in the very early 90's from Logan to Canal Winchester and from Jackson to West Junction during the Jackson Apple Festival. I worked as a volunteer on both excursions and was most likely on that train in the picture. 71 was indeed a great engine and the inspiration for my screen name. Ah, the good old I&O days. I've got a few pictures from Jackson that I can post and I might have some from the Logan-Canal trips, but I'll have to dig a little.
