Kevin and all, photographic evidence from the files of both Ron Flannery and Steve Dolzall indicate that some mixing of Monon - L&N units before the merger did happen (although rarely), and of course after the merger was commonplace, particularly in the coal fields. I personally never remember running or seeing any of the mixed consists, so this photo was new to me. Thank you for posting it. Another interesting piece added to the historic Monon archives. / Ron
