It appears that it is a repaint of Ben Neal's USRA 2-8-2 light but an older version than is currently available on his site now. (you might want to look at the script files there)
Cheers
Edit: Well I was on my way to bed when it dawned on me that I had not tried just plain deleting the script. Did you know that the engine sounds fine without the script? It does produce another script error due to the cab/fireman though.
