I'm stumped! I recently bought my daughter a basic HO starter kit (a Bachmann Red Rock Express). It was working without any problems since the day we bought it. She had been running it the past few days with just the locomotive. Today it was running fine. Everything was turned off and unplugged, we put the remaining 3 cars on the track, coupled everything, plugged it back in and turned it back on, and....nothing. The headlight comes on, but the motor doesn't make any sound at all. 
I know these are cheap locomotives, but it just seems really odd that the motor could be burned out so quickly. The locomotive has been run for less than 2 hours since we bought it. I tried disconnecting everything, pulling all the cars off the track, even disassembling the track and then putting it all back together. I checked several times to make sure the wheels were lined up on the track properly. The locomotive is receiving power because the light comes on, but that's all I know.
Is there anything else I can check to troubleshoot? Any help would be greatly appreciated! Thanks everyone!
