i bought this sp daylight gs2 6-18007 a year ago from a well known dealer.[along with the full set of 5 cars]. it was NOS. If i run the loco & tender alone, it will run all day. BUT, when pulling 5 to 7 cars, goes for approx 10 minutes, then dies. After waiting another 10 minutes or so, it will run again. [its a simple conventional loco]. it doesnt SEEM to be running HOT, i cant find any type of POLY-FUSE, i cleaned/ re-lubed it, put new brushes in, and the wheels/motor will turn freely,no binding, I dis-connected the smoke unit, thinking this may be a draw. NO LUCK. the cars all pull freely without any resistance. ??? im stumped. does one or our forumites have a clue to what my/this problem is ? thanks, Paul.
