First of all, for reference I have relating to the questions: Two P42's, simple layout, and will get two of the P42 MRC Decoder #1645 for each P42.

I really want to get DCC on my simple layout and a friend told me to get the E-Z Command DCC System because it would be pretty good for what I have and need. I watched videos on this DCC controller and have two question:
1. If I have my two P42's engines back-to-back and their both consisted and running normally together... How would have it so ONLY the lead engine's horn goes off when I tell it to and not the help engine too?
2. The only features I'd use with this would be basically horn, bell, lights (dim, bright, ditch lights), and that's basically it. Would this be a good DCC beginners choice of a DCC controller?

I have no experience with N scale in DCC (which is what I'm getting) but quite a bit with HO Digitrax DCC so I don't know how different some of the features would be and if they'd be confusing to set up. And I have watched Bachmann's video tutorial on YouTube.

Thanks, Nick.
