I finally got up the nerve to look inside the engine and it looks like both drive shafts/u-joints have fallen out of place.  Is this common and what holds them in place to begin with? 

Here's an update:  The train motor makes a sound when speed controller is revved up.  The headlight does not come on.  I emailed Bachmann Tech support last Friday but they have not gotten back to me.  Do you guys think that taking the train/set to a hobby shop is the best option at this point? 

Thanks for the tip.  Any idea about the date/age of this set?  It can't be too old because there's a website printed on the box! 

I just purchased an older train set The Comet model #00671 and I've set everything up but the wheels seemed to be locked up.  The instructions say to rock train back and forth on the track.  I've tried this with no luck.  Any ideas to loosen the wheels?
