I have some old 8mm conversions of Southern 4501, S&A 750, TVRM 630 from the 80's and NW 611 and 1218 from '87 or 88 on my YouTube channel....just search and you will find em.
I took the picture, Knoxville for certain. That's the North Gay Street bridge that's seen in the far background to the left.
T&P 610 is a beautiful photo. Her Water Buffalo looks similar to the L&N Big Emma tender in the photo below. Though I'm sure T&P had similar tenders. #41663 was supporting a steam pile driver repairing a trestle near Gulfport, MS in October 1971. BTW, those "trespassers" are now 62 and 65. Of course, being mature adults, they no longer trespass. LOL
