Out-of-the-box Class 66 component interfaces

Railnova’s real-time remote monitoring device Railster enables you to connect to and to monitor the following components on the Class 66 out of the box:


Monitor battery voltage, capacity, current, and the status of both the main and the supporting battery when your Class 66 locomotives are running and turned off.

EMD engine

Monitor relevant EMD fault codes in real time and alert employees automatically when they need to take action on specific fault codes.


Collect fault codes and parameters from the main processing unit, as well as usage counters (km, kwh, engine hours) for accurate maintenance planning.


Track the location of your locomotives, the distance they traveled, their speed and their GPS history. Use real-time GPS data for geofencing alerts.


Track and be alerted about (low) fuel levels and refuels, follow up on fuel consumption per route to achieve fuel savings.

Out-of-the-box use cases for Class 66 locomotives

Battery monitoring

A low battery voltage, or battery failure can cause delays, cancellations and even damages to a locomotive battery. Real-time battery monitoring and battery alerts enable you to detect anomalies and avoid battery failures on your Class 66 fleet.

Fault code monitoring

Retrieve EMD fault codes from your assets in real time, make it easy to cut through irrelevant fault codes or noise by setting up your own (notification) rules and enable people to act on the critical fault codes.

Fuel monitoring

Monitor fuel levels and fuel consumption in real time. Be alerted about low fuel levels and refuels, and follow up on fuel consumption per route or load for e.g. fuel saving and eco-driving initiatives. Use alerts to decrease fuel consumption because of idling.


Keep track of the location and speed of your assets, view GPS history, track traveled kms for maintenance or billing purposes and set up geofence alerts to alert you of location changes or to send alerts to the right people based on the location of your assets.

Digital maintenance planning & communication

Schedule events online and keep a full overview of the planning and progress of all corrective and preventive maintenance interventions for your entire fleet in one place. Share your planning and intervention details with clients, maintainers or other stakeholders.

Usage-based maintenance

Capture readily available real-time counter data, enter counters manually or compute your own to automate your preventive maintenance scheduling based on the actual usage of your Class 66 assets.

Corrective maintenance workflow

Have your drivers or hotline personnel report corrective events straight from their phones, tablets or computers. Use QR-codes in your locomotives for fast and user-friendly defect reporting.

Data access

Already have systems in place to analyse data and to make it actionable? No problem, you can use the Railster to connect to the relevant data sources and to stream the data to your own systems in real time.

Data exploration

Not sure yet what kind of data you can access from your assets or not sure what you can actually do with that data? Connect the Railster or Railster Development Kit to any data source and explore the available data to identify new use cases.
