Temperature Sensor
Railway Metrics and Dynamics’ system solution consists of temperature sensitive bolts from Strainlabs in conjunction with PMU sensors. The bolts send their information to nearby PMUs, where the information from the bolts is analyzed together with the data from the PMU.
The combined technology analyzing temperature data in real-time, provides efficient protection from derailments caused by thermal overload in the wheel axle box. The smart bolts detect the increased temperature in thermally overloaded wheel axle boxes, while the PMU registers changed vibrations in them – either immediately when a derailment occurs, minimizing the infrastructure damage, and in the best case, before the derailment even occurs.
Connected IoT Bolts
The smart bolts are manufactered by the Swedish company Strainlabs, which entered into a partnership agreement with Railway Metrics and Dynamics during 2024. The connected bolts provied yet another dimension of information that is seamlessly integrated within our own proprietary system solution.

Kingpin Lock Sensor
The Kingpin Lock sensor constantly monitors the kingpin lock to ensure that it is properly engaged at all times. The kingpin lock is a crucial component that prevents cargo trailers from separating during transit.
Digital Shunting Tool
RMDs digital shunting tool is based on equipping wagons with PMUs and serves as a tool to help customers move away from the manual handling still in use. The train dispatcher can assemble new train sets using the ”drag-and-drop” functionality.
