Bill,
Out of curiosity, I located this super depressing list of C&NW train wrecks:

Having just quickly skimmed the engine column for the number shown, and the details column for "trolley", I didn't find a good match. The two trolley accidents that I found involved a passenger train and an express, respectively. Clearly not this photo.
Maybe Bobby has more info.
