So I got my first DCC locomotive in at the same time I got my DCC starter kit - the DigiTrax Zephyr Express.  I connected it to my test track easily enough - it only took about 10 minutes.  I just used the defaults for everything right now since I've only got the one locomotive.

I then hooked everything up to my loop and added some rolling stock to see what happens.  I've heard bad things about n-scale sound but this didn't sound bad - it was a little thin but pretty good for all that.

I've attached a couple of videos here...
