Java interfaces and sample implementations for controlling a model railroad layout from a personal computer. JMRI is intended as a jumping-off point for hobbyists to build their own layout controls. Includes the DecoderPro and PanelPro applications.
We are very pleased to announce that the 2.3 series of JMRI test releases has resulted in a version that's good enough to be recommended for general use, including by new users. We're therefore making that version, "Production release 2.4" available for download today.
There have been more than a hundred updates, new features and bug fixes since version 2.2 came out roughly five months ago. For more information, please see the release note:
The release note also contains the download links for Mac OS X, Linux and Windows. (That's our subtle way of trying to get you to read the note).
