Control Device Types are generic groupings of electronic devices used in model railroading. We preload MRRM with a large array of model railroad control device types. The structure of the table allows you to add additional control types as you need them.
This figure shows a portion of the control device type currently defined in MRRM. For each type of control device, there may be many manufacturer models available for your use. You may add your own type(s) if none provided fit your needs.
