LAM: Lateral Acceleration Monitoring
Lateral Acceleration Monitoring is an on-board monitoring system detecting abnormal lateral movements in real-time, thereby enhancing passenger comfort, reducing injury risks, and functioning as a predictive maintenance tool.
What is Lateral Acceleration Monitoring?
Lateral acceleration monitoring (LAM) on trains involves measuring the lateral forces experienced by the train as it moves along the track, allowing for the assessment of the train’s stability and adherence to safety parameters during curves, switches, or other track conditions that may induce lateral forces.

Key Features
Configurable alarm levels
Operators have the flexibility to configure multiple levels of alarms customising them to suit specific safety thresholds or operational preferences. The system’s customisable alarm settings ensure that operators receive timely alerts tailored to their unique requirements. This empowers operators to proactively address potential safety risks and optimise operational efficiency based on their specific needs and priorities.
Real-time data processing
The LAM system captures and processes data in real-time, following industry-standard methods like those in UIC 518:2009. This capability enables swift analysis of lateral acceleration values, empowering operators to promptly make informed decisions. By monitoring and analysing vibrations continuously, operators can address safety concerns and optimise operations in real-time, ensuring seamless operations and enhancing safety, efficiency, and reliability across their rail networks.
Designed with redundancy
Redundancy can be built into the LAM System, further enhancing its reliability. Redundancy ensures that even in the event of a sensor failure or system malfunction, there are backup mechanisms in place to continue monitoring lateral vibrations effectively. Redundancy minimises the risk of missed detections and ensures continuous monitoring, contributing to the overall safety and reliability of rail operations.
How does Lateral Acceleration Monitoring work?
Accelerometers are placed in the axle box and on the car body. As the train travels, the vibrations measured by these sensors are processed. Should these vibration measurements trigger the threshold values, an alarm is set.
- Measure: Accelerometers are placed in the axle box or on the car body.
- Convert: The vibrations measurements are converted into lateral acceleration values, providing quantifiable data on the train’s lateral movement.
- Assess: The lateral movements are assessed to determine if they have exceeded the criteria for acceptable lateral accelerations.
- Alarm set: An alarm is set to either notify maintenance teams about abnormalities or even automatically stop the train in case of immediate danger.
