This engine seemed to work perfectly when first received, but I recently realized that one set of wheels has not been turning at all and has, in fact, become flat on one side. This suggests that the wheels have never been turning on that side. It says something positive for the motor that it was able to push the locomotive despite having one set of wheels not turning, but not much for quality control. Since the locomotive was relatively inexpensive, it seems that it is not worth spending money to have it repaired, so it seems that I wasted what money I sepent.
RAN GREAT WITH STABLE RESPONCE TO ADJUSTMENTS IN SPEED. NO PROBLEM WITH TURNOUTS.THE ONLY PROBLEM I HAD WAS THAT TO RUN CONSISTANTLY, I HAD TO REMOVE RUBBER "O" RINGS SO IT WOULD NOT LOSE POWER GOING OVER TURNOUTS.
