Overview

• Engine Driver is a dedicated mobile throttle application designed for model railroad enthusiasts.

• It works in conjunction with control systems such as JMRI (Java Model Railroad Interface), MRC WiFi, or Digitrax LnWi.

• The app enables hobbyists to operate their Digital Command Control (DCC) locomotives wirelessly, providing a realistic and interactive driving experience.

Connectivity and Compatibility

• Connects to a WiThrottle-compatible server, such as the one provided by JMRI.

• Supports MRC WiFi interfaces and Digitrax LnWi modules.

• Designed to be used with home or club layouts that have a compatible command station and network setup.

Locomotive Control

• Operate between one and six DCC locomotives or consists simultaneously.

• Control direction (forward or reverse) with smooth transitions.

• Adjust speed precisely using the touchscreen throttle controls.

• Access up to 29 user-configurable functions such as lights, horn, bell, or custom sound triggers.

Layout and Accessory Management

• Operate turnouts (track switches) individually or as part of pre-defined routes.

• Manage layout power, enabling or disabling track voltage as needed.

• Integrate with JMRI web server features for additional monitoring and configuration.

Setup and Operation

• Requires a compatible command station and network connection.

• Follow the setup instructions on the official website to connect the app to your system.

• Offers flexible configuration options to match different control preferences and layout designs.

FAQ

Q: Which command stations and network interfaces are compatible with the app?

A: The app connects to any WiThrottle-compatible server, such as the JMRI WiThrottle server, and also supports MRC WiFi interfaces and Digitrax LnWi modules. As long as your layout has a networked command station that speaks the WiThrottle protocol, Engine Driver Throttle will be able to communicate with it over your local Wi-Fi network.

Q: How many locomotives can I operate at the same time?

A: You can control up to six locomotives or consists simultaneously. Each locomotive appears as a separate slot on your screen, allowing you to switch between engines, control their speed and direction, and activate functions without having to re-address the throttle each time.

Q: How do I connect the app to my command station?

A: After installing Engine Driver Throttle on your mobile device, you simply enter the IP address and port number of your compatible WiThrottle server in the app’s connection settings. With your device on the same network as your command station, tapping “Connect” will pair the app with JMRI, MRC, or Digitrax hardware almost immediately.
