JMRI is a Java-based cross-platform application for model railroaders. JMRi contains applications for:

The programming of Digital Command Control (DCC) decoders, (DecoderPro®) (DecoderPro3®).
Drawing computer based panels for depicting a model railroad layout , (PanelPro® ).
Controlling the layout , (Layout Editor).
Creating train manifests for duplicating railroad operations, Operations
Controlling the signals on the layout
Controlling lighting and sound in the room, and so forth. (SoundPro®)

All this capability is contained in one program (JMRI) which has several “start-up” screens for the various applications.

JMRI® version 2.12 can run on any computer system that will run Java 1.5.0 or later, whether it is Macintosh, Windows, or Linux based. It does require that Java be installed on the computer. JMRI® version 2.14 and later requires Java 1.6.0 or later. You can get Java as a free (but very large...) download at:
