JMRI: CTC Tools
This help placeholder is for the "new" implementation of CTC that provides capabilities beyond USS CTC. See here for information on this new CTC implementation. It provides a GUI editor to configure the CTC rules and a run-time to implement CTC logic. It also builds a skeleton Panel Editor CTC panel with the turnout levers/indicators, signal levers/indicators, code button, etc., and a minimal track plan.
The original implementation of USS CTC tools (requires scripting) is discussed here.
