I wanted to add that there are no built in coupler pockets on these trains.  The coupler attachement is on the wheel assy.

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?

Great suggestions.  Maybe I'm overly concerned about this but is there a mximum voltage for the turnouts?

WOW, I'm overwhelmed by the responses.  The model railroading community certainly is  a helpful group.

I'll look into the dedicated power pack for the turnouts.  I noticed in the thread that there are a range of AC voltages noted for the turnout operation (16-18 VAC).  Is there a maximum voltage or limit?  I have checked and some power packs indicate they output 20VAC.

Also, since I'm using EZ Track, the terminal re-railers have plugs as the connector and there is a plug on the command center.  Based on what is written below for the turnouts, I should feed the power from the command center to a terminal block and then feed each terminal re-railer from there.

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?
