Innovative inertial solutions for Railway

At the cutting edge of inertial technology, Meggitt (Sensorex) is delivering innovative solutions to the main railway signalling companies, enabling them to develop state-of-the-art architecture in a safe environment. In cities as well as on mainline, its EN 50155 certified products address the specific needs of any operating environment. These products are based on accelerometers, gyrometers or stand-alone Inertial Measurements Units (IMUs) hybridized with other on-board sensing systems or existing worldwide satellite constellations.

Meggitt accompanies the Railway industry virtual block migration that renders most of the current track side equipment, such as balises, axel counters or radar, out-dated. These sensing solutions are central part of the on-board intelligence and address green field and brown field signalling solutions, hence reducing carbon footprint.

To date, our sensing solutions are covering the latest signalling innovations and the Company delivers to the main industry customers’ product with boosted intelligence. Our algorithms and Kalman filters are the result of more than 30 years of Railway expertise in any grade of automation line type.

Meggitt (Sensorex) solutions are today found on-board in every continent, from Europe to South East in countries such as Asia, China, Japan, Africa, Australia and Americas.



In the frame of ambitious renewal programs or new line signalling equipment installation, railway operators are aiming for interoperable solutions which are able to increase speed and traffic frequency, reduce costs and maintenance expenses while guaranteeing maximum safety.

Meggitt (Sensorex) sensing solutions for main lines are adapted to any line configuration, from high speed to regional or intercity trains. Every single solution is conceived and developed by a team of Engineers that benefit from our railway expertise, delivering smart solutions for SIL4 architectures with their respective technical constraints and safety boundaries.

Meggitt (Sensorex) is the world leader of sensing solutions for railway, from any ERTMS systems to Level 2 Baseline 3 environment, delivering products for train positioning, navigation system, odometry, enabling virtual mobile block definition towards higher traffic capacity and maximized productivity on existing lines.



Meggitt (Sensorex) is extremely present on the mass transit sector, enabling smart solutions to CBTC architectures, enabling high traffic capacity with reliable inertial information to the OBU.

Its products require minimal installation operations or maintenance, enabling low life cycle costs with robust technical and economical solutions. These systems can be easily deployed, enabling urban areas in the world to address their transportation needs quickly and safely.


Light Rail, Tramway and Freight

Meggitt (Sensorex) is recognized for its know-how in deploying its sensing solutions to address light rail specific signalling standard, delivering technical support for tramway and light rail operation. The company also participates in major freight signalling solutions in major projects in Australia and South Africa.
