Not exactly a patch job since the unit retains it's original number. This unit is an example of the curosities one can find on the internet.

First of all, here is a photo of the same unit a few months later, still sporting it's handsome new UP herald. [stkntower.railfan.net] Stockton tower 12/97

Next, here is a listing showing the unit was renumbered to UP 1451 on June 3, 2003.

And finally, here is a photograph of the unit on July 27, 2007. The locomotive in this photograph lacks the amber "gumball" flasher on the roof that had replaced the gyralights and the former classification light openings have been more securely welded up. Is this the same unit? Would someone bother to repaint the nose?
