I am very new to model railroading and have been reading a lot about JMRI and DCC Controller, but I could not find anything with relation to the Bachmann Digital Commander. I understand that you can use JMRI with a Digitrax PR3 to program decoders, but I was more interested in controlling my trains with the software. I did read that, in order to do that, you need the JMRI software, a PR3 interface and a Digital Command station, but what I am not clear about is if the Digital Command station can be  a Bachmann Digital Commander, or will I need to invest in another Digital Command station from Digitrax? Also, if I need to buy a new command station that which one is advisable to buy. Thanks guys.
