JMRI users

Discussion group for people using the JMRI® model railroad software suite.

The JMRI suite provides several useful tools such as:

  • DecoderPro® to simplify configuring complicated DCC decoders by providing screens on which you can select the various options and values you want.
  • PanelPro™ makes it easier to control panels, set up signalling, configure operations and control your layout.
  • SoundPro™ generates sound tracks for your railroad layout through use of your PC's sound card.
  • JMRI Operations for computer generated train switch lists.
