It doesn't seem like there is one of just the train. My advice is getting a transparent png of the logo and erase what you can of the lettering and use a line tool and fill in the missing gaps. It might be more tricky near the front of the train, but a lasso tool should help with that.

Yeah I kinda figured, which sucks cause I REALLY wanna make a good fanmade logo. Darn that train. lol
