Railway Metrics and Dynamics aims to be the first on the market with a complete system in a unique category, with a superior product based on patented technology

Fault detection

The PMU detects and reports many different faults

Train status

The technology

The Performance Monitoring Unit (PMU) is a real-time sensor that is easily mounted on the bogie, i.e. on the undercarriage-carrying wheelsets.

Efficient wagon registration

The PMU can also be equipped with near Field Communication (NFC) which facilitates highly efficient wagon registration.

Internet connection

The sensors communicate with each other, and with the main unit within the locomotive, through radio signals. The sensors also communication with the cloud through any available internet connection.

Digital interfaces

The information from the system is presented in real time in a digital interface. In addition to warning signals, the interface can also display utilisation and keep track of maintenance cycles.
