hi guys. i just got my 1st train set 2 days ago. its a bachmann centennial 24007. did put oils and grease (saw the video on youtube on how to do it). it was working for less than 3 hours total. turned it on for abt 20-30 mins max then let it rest for hours then turned it on again. then it stopped moving. there are lights on the passenger cars and at the locomotive so i dont know whats wrong with it. did cleaned the track made sure that the track is connected. unplugged it for 5 mins then plugged it on again but still doesn't move. it was quite noisy when it was working and saw a comment in youtube saying that it is normal. need help pls. thanks.
