I read on a post that you should break in a DCC loco on a DC system but I cannot find that post and do not remember the details, so what is the best way to break in a new DCC Loco?

Is there a way to connect Bachmann EZ Mate couplers to a car that has couplers mounted on its trucks?

I am starting a layout using Bachmann EZ Track and a Bachmann EZ Command DCC controller. My question is do i wire the EZ Track the same way as a conventional track with the bus wire and feeder wires connecting the track to the power supply?  The plan book that came with the first set only shows connecting the power through a power rerailer track and only one per layout, but that is using DC not DCC.

I have a EMD SD40-2 loco that I am looking to upgrade to DCC with a Bachmann decoder.  I was wondering how I can tell which decoder to get, the one with the plug or the one to hard wire?

What do you need to do to the second loco to make it run in reverse when you use two loco on 1 long train?  Is there an advantage to running 2 loco's on a DC layout or do the two just share to power?

I am just getting back into model railroading after 20+ years away and was wondering if the E-Z Command system could be used on more than 1 track layout?
