  • Switch condition monitoring (SCM) enables operators to reduce switch failures and optimise maintenance processes. Switch failures can be the result of mechanical, environmental or electrical problems and often require multiple departments or experts to find a solution. 

    Use intelligent switch condition monitoring systems such as ROADMASTER® SCM to detect impending failures at an early stage. Maintenance can be prioritized based on the asset condition, and the additional information provided by ROADMASTER® SCM enables targeted troubleshooting. Measuring points for this can be custom-defined to meet your requirements and more points can be added at any time. That guarantees maximum flexibility and planning security. As a result, you can introduce required measures promptly, prevent failures and ensure maximum availability.

  • Train Detection Monitoring (TDM) systems can predict failures of various train detection methods and capture intermittent faults.

    The various methods of train detection (including track circuit or axcle counter) are a vital part of many signaling systems and maintaining their performance is fundamental to the safety and efficiency of the rail network. TDM reliably identifies deterioration in performance and issues alerts to allow maintenance before failure. Non-invasive sensors monitor for example energy levels at the track circuit receiver and send real-time data to a central server where it is analyzed using specialist software with preset multiband alarm levels to detect when the operating characteristics of a track circuit start to deteriorate. Alarm events are sent to designated users who can react immediately and initiate necessary actions in a timely manner.

  • Rail Crossing Monitoring (RXM) solutions automatically detect crossing faults and assist investigation work. Rail crossings are a critical interface between the railway and the public that require regular maintenance and testing to ensure safety. 

    RXM monitors records the performance of rail crossings to enable proactive maintenance. Event recording produces a precise chronological log of the status of all controls and indications associated with the rail crossing operating system. Real time condition monitoring enables continuous data acquisition of the rail crossing components and sub-systems that may deteriorate between routine maintenance and inspection. Information is sent over a fixed network or wireless connection to a central server through which the maintainer receives maintenance notifications.

  • With Signaling Power Monitoring (SPM) operators can find and fix power problems before performance is affected. Signaling systems represent a central safety relevant element in all railway systems.

    The performance and reliability of signaling systems is dependent on the quality and availability of the power supply network that feeds them. Signaling Power Monitoring (SPM) offers rail operators the opportunity to remotely monitor power supplies. The measurement of parameters such as voltage, current, battery condition and insulation resistance provides valuable data to the rail operators. This enables a comprehensive diagnosis of problems that may occur in power supplies, which shortens response times and ensures optimum availability of the signal systems.

    More information:

  • By monitoring rail movements, rail breaks or changes in temperatures impending failures are detected at an early stage, and sustainable measures can be initiated even before rail operations are negatively impacted.

    With our intelligent system ROADMASTER®, we record the condition of your infrastructure permanently, which enables you to remotely monitor rail movements and changes in temperature. Additionally the Ultrasonic Broken Rail Detector System reliably identifies rail breaks. Both areas can have a significant impact on the operability of the track, installed assets and rail expansion joints.

    ROADMASTER® TRM offers the possibility to detect arising problems at an early stage. For maximum safety and availability.

    Growing rail traffic worldwide requests higher safety standards and lower maintenance costs at the same time. An essential aspect is a continuous, trustworthy monitoring of wheel-rail interaction forces.

    Wheels of rail vehicles are exposed to high wear and tear. This may result in geometric wheel defects. The functions PHOENIXMDS WDD/WIM measure on a continuous basis every wheel of the fleet and check for any deviating force levels during normal train operation.

    Besides detecting wheel defects the functions are used as a dynamic rail scale at the same time; vehicle weight and load distribution are monitored during every passage and an unbalance or overload can be recognized in time. Assistance for optimal payload usage is available as well.

    More information:

  • Hot wheels and hot boxes are a major threat for any railway operation. A hot box can lead to fractures of axle journals that might cause a derailment. Remarkable operational hazards are caused by locked brakes, due to overheated loosened wheel rims as well as broken wheel disks. A locked brake can cause fire and is one of the main reasons for the formation of flat spots. Additionally, not functional brakes can lead to very dangerous situations and significant wear and tear.
    The Hot Box and Hot Wheel Detection functions PHOENIXMDS HBD/HWD are solutions to decrease the mentioned faults to guarantee a safe railway operation. Monitor reliably the temperature of axle bearing boxes, wheel rims and brake discs of passing trains up to 500km/h.

  • Train equipment such as couplings, chains or hoses could be dragged under the train damaging the infrastructure. The function Dragging Equipment Detection (PHOENIXMDS DED) protects humans alongside the track, crucial fixed assets such as switches, crossings, ETCS balises or signals against these kind of damages. When components are being dragged with a train, DED generates an alarm to traffic control or to the train driver in real-time to limit consequential damages. Alarms are generated at user-defined tolerance levels. The system provides information about the position of the dragging equipment at the train, the side where the impact was detected and the severity of the strike.

    More information:

  • Slipped loads due to improper fastening or travelling vibrations of train vehicles are major issues in railway transport. Objects sticking out of a train's reference profile can cause serious injury to persons and can lead to extensive damage to railway infrastructure.
    The Profile Validation System (PHOENIXMDS PVS) is designed to detect reference profile violations on passing train vehicles. This precise and reliable surveillance system protects persons and railway infrastructure and avoids accidents with passing trains. Event based image recording allows the operator to verify the alarm and identify the severity of the profile violation.
