Portfolio

Ensure the highest system availability with railway measurement & monitoring solutions

With our comprehensive measurement & monitoring portfolio, we help you acquire critical insights from your rail domain data. It can be very easy – for example, an automated measurement of asset conditions during a maintenance intervention. Or the continuous collection of condition data during asset operation to derive trends and get early notifications about critical deviations of train and track. The automated collection of image and 3D data can also be used to generate a digital twin.

Vehicle equipment measurement systems

Optimize and facilitate the maintenance of your rolling stock with VEMS

VEMS provide a range of automated inspection equipment for rail vehicles to determine their serviceability and safety. The VEMS range is a suite of modular measurement solutions installed on or adjacent to the track to provide contactless roll-by checks of vehicle integrity, wheels, brakes, pantographs, and collector shoes. VEMS solutions excel in condition monitoring and provide detailed, objective, and repeatable inspections to support the management of maintenance activities. By detecting critical equipment conditions, they help increase operational safety and protect your valuable assets. The systems are supported by a comprehensive data management system (DMS), including a measurement database and facilities for analyzing, viewing, and exporting measured data – along with tools to connect this data to your third-party maintenance solutions via a standard REST application programming interface (API).

Your benefits from the leading automated vehicle inspection product:

  • Increased availability of rolling stock
  • Cost savings because automatic vehicle inspection almost fully replaces the manual inspection of rail components
  • Improved safety thanks to more consistent measurements and component integrity assessments
  • Superior planning through comprehensive data analyses
  • Optimized lifespan of components until they reach their technical wear limit

Explore the different vehicle equipment measurement modules

Whether you’re planning a new fleet or optimizing the lifetime maintenance costs of an existing fleet, the VEMS modular design ensures that you achieve a fast ROI on your maintenance equipment investment. Any VEMS installation can include one or more of the following field-proven vehicle measurement modules customized to meet your operational needs.

VEMS for wheel profile measurement

The Wheel Profile Measurement System (WPMS) provides highly accurate automated measurements of all wheel parameters required by international standards as well as additional parameters and reports focused on reducing costs through increased wheel life. The hardware design is centered around line replaceable units that ensure industry leading availability of the system with low lifetime costs. 

VEMS for brake measurement

VEMS for brake are based on high-precision, non-contact measurements of the friction materials and brake components. These systems measure the wear of brake pads, brake discs, brake blocks, and brake shoes and can compare wear trends across axles, bogies, trains, and fleets. Any missing components, such as brake pads, are reliably identified.

VEMS for pantograph wear measurement

The fully automated VEMS for pantograph measure the integrity of the components. The recorded data can be trended to derive wear rates and predict service life. And the measurement records can be stored, analyzed, viewed and reported in the MRX Data Management System (DMS).

VEMS for visual inspection

The Visual Inspection System (VIS) replaces traditional labor-based inspection with computer vision and machine learning. The modular design allows the system to be configured to meet the maintainers business case. Possibilities include a system that monitors an individual bolt, all the way up to a full 360° whole vehicle integrity solution. The system generates tabular reports for specific measured values and complete image file for audit and review purposes.

VEMS for wheel tread measurement

The Wheel Tread Measurement System uses patented technology to generate a complete 360° model of the wheel tread as it rolls by. From this, the system analyses each wheel for cavities, flats, and out-of-roundness in milliseconds instead of hours that a current full vehicle inspection can take. This approach also removes the time-consuming process of stopping a train and lifting each axel to make a manual 360° measurement.

Broken rail detection

Monitor your track status and detect rail breaks with the broken rail detection system

The train-mounted broken rail detection system checks the condition of the rail network during operation, identifies any damage, and reports the rail status to the following train. This increases throughput, because tracks can be quickly maintained and released for operation, instead of being blocked for days due to damage. A break in the rail can be identified with a very accurate GPS position, facilitating identification and repair. Our broken rail detection system improves rail safety and operation by significantly exceeding the performance limitations of current detection technologies. It’s easy to install and operate on a variety of rail-based vehicles and it’s simple to integrate in existing signaling and maintenance solutions.

How the broken rail detection system keeps track of your rail status

Each train is equipped with a pair of sensors on one of the bogies. While the train is in motion, these sensors scan the tracks to the millimeter and reliably detect track damage even in harthard-to-reach and dark areas and where no physical separation has yet occurred. An on-board unit reports the damage to the back-office system for verification. Within seconds of detecting a rail break, the message is forwarded to the signaling system, train control, or interlocking so that immediate action can be taken by the next trains passing the located rail breaks. Rail break detection provides near real-time detection and verification of rail breaks – for a safer and more profitable operation.

  • Reliable detection of broken rails throughvia continuous monitoring of the entire rail network.
  • Prevention of derailments duethanks to rapid warnings to the following trains.
  • Increased safety and especially cost-efficiency by adjusting inspection intervals and reducing the need for maintenance personnel on the track.
  • Reduced effort thanks to the fully autonomous platform that runs on revenue trains during operation.
Digital track capturing

Measure complete rail track sections with digital track capturing

Digital Track Capturing (DTC) is an innovative approach to measuring complete rail track sections in a short period of time using modern LiDAR scan technology and precise GNSS geo reference methods. The digital results can be used for measurements and for investigating environmental situations in the field. The whole project team can do digital site surveys using the digital twin, without the cost of a business trip. With this digital twin, it’s no longer necessary to take measurements manually – which means that safety issues are minimized on the rail track.

Your benefits from our digital track capturing solution:

  • Building information modelling basics: capturing of actual data, measurement of gradients and distances, enhances with geo references/data
  • Publishing: More intuitive data publishing for customers via Web Viewer
  • Analysis of clearance profiles: survey of tracks and vegetation, collision tests, control of static and dynamic clearance profiles
  • Full project management: enables quick project processing for conversions or vehicle tenders based on higher, more up-to-date, more accurate, and above all digital data quality
Track monitoring smartphone app

Make every train a monitoring train with the track monitoring smartphone app
