I've sanded down all my track gaps between the rails at the track connections to make the wagons run as smoothly as possible...but in some areas there are gaps of 1/16" or so between the rails. What is used to make the gap smaller? Is there a glue? Bonding agent? Espically around the turns and near the turnouts, these gaps are troublesome. Since I used Bachmann E-Z track, I had little ability to move the rails to "even out" the north or south track gaps. So, what's the best method to get rid of the gaps? Thanks again guys.
