Thanks guys it was the power pack itself I went to the local train/hobby store and got an old one that looks like it will last forever.

I have an On30 train I picked up for a Christmas village last year.  After hooking it up this year it won't run.  The light on the power pack is red when it's all connected.  The light on the train does not light up.  I changed the layout to see if maybe if it was a connection issue and it doesn't seem to be.  I don't get any dc current off of the track when I touch both sides with a multimeter.  I'm not well versed at all in troubleshooting these issues.  Is there any kind of step by step troubleshooting guide somewhere or can someone guide me with some ideas for what I should do to try to fix the issue?
