In the field of engineering services, evopro uses latest trends in technology, metrology, and software development, which are combined with a research and creative design attitude, to create new and innovative railway diagnostic systems.

The company’s railway diagnostics measuring systems help to increase the safety of traffic and efficiency of railway transport.

Rail infrastructure diagnostic systems

evopro Innovation offers its partners track and on-board measuring systems to continuously monitor the condition of rail vehicles and infrastructure. Measuring systems enabled increased rail transport safety and passenger and freight transportation efficiency.

The eRDM240 is a dynamic wheel load diagnostic system (WILD) for the measurement of wheel load, axle load, wagon load, and the detection of wheel defects at travelling speeds. evopro Innovation received the Hungarian Product Grand Prize in 2014 and the Innovation Grand Prize in 2015 for the development of the eRDM240 measuring system. The system can recognise overloaded and unevenly loaded cars and wheel and vehicle faults, in addition to sending automatic alerts to designated reporting locations so that any issues can be quickly repaired.

Advantages of the eRDM240 system include increased safety and operational axle load and track usage control, as well as the ability to compare declared and measured axle loads. The system can also highlight any vehicle problems while preserving the condition of the railway track and increasing its use. In addition, it supports condition-based preventative maintenance of railway vehicles, which can help to reduce repair costs.

Battery powered temperature sensors for railways

The eRTM system is a wireless, battery-powered sensor network that measures the temperature of the rails in real time, thereby measuring the internal stress distribution of the rails.

This helps to increase safety by preventing derailment during high temperatures by using real time indications of weather conditions that could cause possible rail buckling. Operating costs are also reduced as damage from derailment is prevented, which extending the lifetime of both the assemblies and the network. During cooler temperatures, automatic variable heating control can also be used to save money and energy.

Effective traffic management also allows for increased economic efficiency and profitability as the duration, extent, and location of speed restrictions can be optimised by monitoring rail temperature conditions in real time. The infrastructure can also be operated in a more sustainable way, as railway track failures can be predicted based on historical temperature conditions. This allows maintenance operations to be optimally scheduled.

Railway accelerometer systems

The eRVM railway vibration diagnostic system is a multi-channel, three-dimensional accelerometer system that can be built into the track or installed onboard. The wayside eRVM system detects wheel defects and other irregular conditions of the passing trains.

The onboard eRVM monitors the dynamic behaviour of the vehicle components and the impact forces applied to the vehicle and goods. The system can measure the dynamic forces acting on the chassis and detect wheel defects and bogie problems. Diagnostic modelling of the vehicle is carried out by equipping the axle, bogie and chassis, and axle counting.

In addition, the track condition is also monitored by measuring the track’s vertical movement and deflection, as is the quality of special loads being transported to ensure that they arrive in perfect condition.

Technical condition monitoring for railways

The eRCM railway vehicle diagnostic service is suitable for the continuous technical condition monitoring of each wagon and passenger car. The data from the trackside measuring systems are then used to identify trend-like or significant changes in the diagnostic characteristics derived from the measurements.

Advantages of this service include raised levels of traffic and increased operational safety. The condition of railway vehicle wheels, axles, and bogies can be monitored, allowing trends or sudden and significant changes in technical conditions to be identified early, which helps to forecast any future issues. Railway vehicles in inappropriate technical conditions can also be detected.

Economic efficiency is another advantage, as condition-based, predictive, and preventative maintenance strategies vehicle prolong vehicle service life. The cost of maintenance is also reduced by using optimal maintenance strategies at appropriate times. This helps to protect the condition of railway infrastructure as availability is increased while lifetime costs are reduced, and vehicles that need repair can be easily identified.
