Vinny's problem is a real one.  I have run into a similar problem with one switch on my layout.  EZ Track switches ARE power routing and therefore need insulators at certain points.  My train will run fine but if you throw a switch and not have power routing to the rail your train is on it will stop.  In every train book I have seen it says if you have a power routing switch you have to insulate it.  I currently use one train and one power pack but will need to use insulators in a couple of places to ensure proper power.

How would I wire those up (both the SPDT and the two SPST)?

Are EZ Track switches SPDT or DPDT?

My layout is N Scale EZ Track on top of 1" foam.  What is the best way to fasten the track down?  I have heard that ordinary white glue works but I also have been told you need something different.  Any suggestions will be helpful.  Thanks!

What is the best tool for cutting EZ track?  I have some gaps I need to fill and I need to create a custom sized piece.

On some of the switches I used a dremel to file down the throw rails.  This eliminated my derailment problem.

I have some N-Scale EZ track and am having trouble with derailments. Going forward over the switch is okay but when backing up the cars come off the track.  Any suggestions?
