Thank-you, we found a nice hobby store and the owner tested all the pieces. We found it was a bad track/controller connection, and he replaced the piece! Hobbytown in Fairfield, CT, I recommend them highly!

Thank-you for the help.

we bought our 7 Yr old an HO set with "EZ tracks". It worked for about an hour, then we shut it off, and un-plugged the transformer. Later we plugged it back in, and the train would not move. The light on the controller lights, I tested the track with a voltage meter and it doesent seem to be getting any, I did try unplugging everything and waiting for a breaker to re-set.
Thank-you for any help or hint you could provide!
