   I recently bought the lighted truss bridge for me HO scale Bachmann Train set (run via the EZ tracks and speed controller. I powered the light through a Light Hub and now my train will not run (I can't even power up the controller).
Did I foul up by powering the bridge from a source other than through the tracks (through the Speed Controller0 and burn something up ?
What is remedy to this problem ?
Thanks
