Thank you,

I have the PS that came with the original set. I will use the ac output that is intended for accessories.

Is there any modifications I should do to the turnouts, or crossover, if I go that way, or should they work out-of-the-box?

Thanks,

I am new to this hobby and had a beginner set to which I purchased an extender but never used. I recently converted the initial oval to DCC. What do I need to do to add the extender set which can connect to the original with a remote left and right turnout? This is all ez trac.
Thanks for any assistance you can provide.
