I don't know when it was painted (I no longer live in the area), but if you exit I-83 after crossing the Susquehanna River (westbound) at Lemoyne, PA the ramp takes you back under the highway. Emerging from the underpass you will spot this wonderful mural. Part of the mural depicts E7 #5901.
So the puzzle for Alan Arnold is ("riddle me this, Batman" ) does a full sized painting of a real locomotive belong in the Real Trains sub-forum?
Well, whether it does or not, I just find it to be very cool. Lionel made this engine and its running mate, #5900, last year and I acquired them.
