Train Throttle

A Windows WiThrottle client for JMRI.

Train Throttle lets you use your Windows device as a JMRI/WiThrottle control. You can access functions 0-28, as well as control multiple units on the fly.


In order to use Train Throttle, you will need the following:

  • A model train layout, powered by a DCC system
  • A device running Windows 10
    • Desktop or Laptop
    • Phone
    • Xbox One
  • A computer running JMRI, with the WiThrottle service enabled, and connected to:
    • Your DCC system via a PR4 or similar device
    • The same network as the computer running TrainThrottle, via Wifi or Ethernet

Note: TrainThrottle is developed against the current version of JMRI (currently 4.16) running on a Raspberry Pi, using a PR3Xtra for communication. If you experience any issues with earlier version of JMRI not working as expected, please contact the developer with the version of JMRI you are using.
