will when i bot it at a model railroad show the man said it works, i got it home and it would run on the easy track set i hade made to test used trains i get.it’s an old streamer that gets it power from the tender and the weels a brass, but when i tryed to put it on my train layout it wouldn’t run.the i picked up the back end of the tender’s wheels and it start runing but when i put them back down it wouldn’t. what should i do becuase i know it’s not the track becuase i clean it real go before i tested it on the layout. the only than i can think of doing is getting rid of the old bass wheels in the back and get a newer pair of brass wheels or just get some plastic wheels instade to put in the back of the tender.
thanks very to the people who can help me.
