Thanks for all the information. To answer USCG Tanker's question I am planning to add an express passenger system/heavy electric traffic. I like the idea of plastic clips. Now the question is what to choose. It is a shame that Bachmann does not make its own cantenary system.

I am planning to do a cantenary system and was wondering what ready made system to use. At present there are a couple of ready made one to use: Marklen, Kato,and Vollmer. Was wondering which one would Bachmann recommend, because it appears they will all need a little modification to work with EZ track.
