CornwallRR

JMRI was used to create the dispatcher control panel for Nick Kulp's Cornwall RR.
Nick's layout uses a mixture of C/MRI and DCC.

The block detectors, turnout position sensors, and signals are all attached to a C/MRI serial system. The locomotives are run using Digitrax DCC. Some turnouts are thrown manually, and some are operated by Tortoise motors connected to SwitchIt DCC decoders and thrown via the Digitrax system.
The layout has 45 signal heads controlled by the C/MRI system. Most have red, yellow and green aspects; there are a couple that also indicate diverging routes with flashing yellow. The signals respond to occupancy to provide an automatic interlocking system.
Originally, the dispatcher worked via applications on two computers. One ran the C/MRI system that showed block occupancy and drove the signals, while another application on a different laptop was used to throw turnouts.
