I recently purchased a Bachmann set with the EZ Mate couplers.  I also have some older Bachmann cars with horn hook couplers.  I want to replace them with the EZ Mate.  Is there a standard EZ Mate type or might each car be differant?

I recently purchased a Bachmann 501 set for my son.  I also purchased some turnouts and extra track to expand the set.  I have realized since that the power pack and controller will not power the turnouts.

I believe I will need to power the turnouts from a separate transformer/power pack and was wondering what would be necessary/adequate to handle six turnouts.  Also, what are the electrical characteristics of the turnouts?  Seems important enought to place on the turnout itself but nothing is there.

One last thought, I am planning to add a 22" oval outside the 18" provided in the set and connecting them with the switches.  I was wondering how many terminals I should expect to include and how are they wired from the single output of the controller?
