Mansteins big guns, chasing bruno
 

this is the third mission in mansteins big guns, It says to kill off everything at the train station, and destroy the transport vehicles, I have gotten rid of all enemy troops, and blown up every vehicle that I can destroy, including fuel trucks and gas tanks and the one train engine that seems to be running, I can't find anything else that will blow up, what transport vehicles are they talking about? I even blew up the tractor that was in the field, but it will not show that main item being complete.

I finally started over and when I had finished all enemy forces, I started blowing everything up including the other train engine, tanks and anything else I could think of, I don't know which one did it ( I suspect the other engine) but it finally showed complete, although it did not specifically tell me when it was completed.
