JMRI model railroad digital command & control software

Engine Driver - JMRI Throttle for your Android device

Drive a model train with prototypical controls, realistic behavior, and simulated physics; uses JMRI's WebSockets interface for layout connection

Sample VSDecoder files for JMRI

Emulates MERG concentrator or MQTT for RFID reader communication with JMRI

WebSocket client for JMRI with real-time throttle control, auto-reconnection, and browser/Node.js support

A Homebridge plugin for controlling a model railroad through JMRI

Simple Node to control a single turnout and 3 2 aspect signal heads and 5 sensor inputs using a Arduino Nano it will work using a usb cable or can use a Rs485 bi directional module 2 wire module

This node is used to control a sliding fiddle yard i have put it here with the permission of Phillip Edward from MERG to assist other in seeing what can be done its based on a Arduino Namo

Operate Märklin MS2 (MFX, MM2, DCC) directly from Rocrail, JMRI, iTrain... with TCP or UDP over WiFi; also handles up to 8 sensor inputs

A model railway controller backend for signal masts-, sensors-, light effects-, actuators and more.

DCC-related protocols implementations

A model railway stackable and large scale sensor and actuator framework

A mobile app for interacting with the JMRI (Java Model Railroad Interface) system built on Nativescript

DCC command station firmware for the Raspberry Pi Pico 2 — PIO-generated track signal, partial DCC-EX protocol for JMRI, LVGL touchscreen UI

A 64 channel servo node based on a Nano here for demonstration purposes only to show what can be done. permission was given to place the code here by Phillip

A swedish signalling system for JMRI

This is to show how 3 trains can be run in one script in jmri

JMRI CLI and MCP server for DCC model railroads — control your layout by voice or chat (Claude, xiaozhi/Kira) or from a terminal (jmri-cli)
