Thanks for your help.  It was a short and it did involve the EZ track connectors. Now I know!

Hello, I'm an O scale AC power guy who wants to run an N scale DC train on my 16 x 12 foot layout.  I have a 56 foot loop for the N scale train.  Like O scale I powered the track every 6 feet with 16 gauge wire connecting terminal block strips.  I connected Bachmann 10 inch straight track with wires to the terminal strips.  Powered it all up and.. nothing.  I was certain to connect all common together and all hot together. 

I then disconnected all the terminal stips and hooked the 56 foot loop up to power with ONE track section.  Now the train runs the full 56 foot loop with only one hook up to my tiny stock power supply!  Go figure.

Although I should "leave it alone stupid as long as it works" , I still have questions.

Don"t DC powered trains need power every 6 feet or so to maintain full power? What did I do wrong?

Thanks, educate me PLEASE
