Was heading back to Tulsa on Route 66 and had my camera with me. Noticed a eastbound train heading to Tulsa so I ended up doing some railfaning, got a bunch of pics of SLWC 4142 and turned out in this one the engineer waved at me. LOL, I didn't even notice till I was looking thru all my photos. If you look close you can see his smile too through the windshield.

Two SD40-2 locomotives engine 4142 at the head of the train, SLWC Stillwater Central Railroad a railroad of Watco Companies, LLC.
