Digitrax LNWI LocoNet Wi-Fi Interface for Wireless Throttle Apps

The Digitrax LNWI is a powerful LocoNet Wi-Fi interface that bridges your model railroad’s LocoNet bus to Wi-Fi throttle apps such as EngineDriver, WiThrottle, and JMRI WiThrottle Server. If you want the freedom to control trains from your phone or tablet — without buying dedicated handheld throttles — the LNWI is the interface that makes it possible.

Whether you’re running a home layout, club environment, or modular setup, the LNWI creates a reliable Wi-Fi connection to your Digitrax DCC system so you can use modern apps with your existing LocoNet network.

What the LNWI Does

The LNWI connects to your LocoNet network and acts as a Wi-Fi access point (or can bridge to your existing Wi-Fi). Once connected, your smartphone or tablet can run throttle apps that speak DCC over Wi-Fi, giving you freedom of movement and intuitive touchscreen control.

• Connects your Digitrax layout to Wi-Fi throttle apps
• Supports multiple simultaneous mobile devices
• Works with popular throttle apps like EngineDriver and WiThrottle
• Ideal for modern, app-based control — no handheld throttle required

Works with All LocoNet-Based Digitrax Systems

The LNWI integrates seamlessly with LocoNet systems including the Digitrax Zephyr Express, Evolution command stations, and others that support LocoNet. This makes it a flexible upgrade for any Digitrax DCC layout.

Why Choose Wi-Fi Throttles?

Using Wi-Fi throttle apps lets you:

• Control trains from your phone or tablet’s touchscreen
• Add as many throttle devices as your layout supports
• Avoid purchasing additional hardware throttles
• Customize throttle layouts with app-specific features

Many layout operators today run a mix of physical throttles and app-based Wi-Fi throttles for flexibility.

Internal Wiring & Setup

The LNWI connects directly to your LocoNet bus via standard LocoNet cabling and can either create its own Wi-Fi network or join your existing one. Once connected, open your chosen throttle app and connect to the LNWI to start operating immediately.
