JMRI, these are four letters I'd heard several times over the last few years but really had no idea what they meant. To find out what these letters mean and they mean I turned to our good friend Jim Scorse. Next we talked with Ron Klaiss a capable model railroader who's just embarked on his journey with JMRI.
There will be a quiz when we're done so pay attention.
