Dear fellow train enthusiasts',

                        I need your advices. What is the best underlayment to use to join together Atlas n scale Flex track with Bachmann E Z track. As some of you may be aware there is a difference in height between the atlas code 80 track & the E Z TRACK.  How do I make sure that the tracks for both the Bachmann & the Atlas are at the proper height. Any suggestions , comments would be appreciated.
