Predictive Maintenance

Fewer Train Service Disruptions and Operational Delays: Shifting from Cyclic Maintenance to Condition-based Maintenance

Smooth and uninterrupted railway operations rely heavily on the maintenance of rail vehicles, components, and infrastructure. Traditionally, a cyclic maintenance approach has been employed. However, this approach poses challenges. If maintenance intervals are too short, it results in excessive maintenance costs, while longer intervals can lead to costly disruptions and failures.

Optimized maintenance intervals enable uninterrupted operations with lower maintenance costs

Determining the need for maintenance and upkeep measures is not solely dependent on elapsed time. Numerous factors, such as

  • utilization and load,
  • environmental and operational influences
  • age of components

influence the wear and tear of rail vehicles, individual components, or infrastructure. These factors are typically measurable. Our core competency lies in monitoring, with a focus on vibration and acoustic data in conjunction with operational data and integrating them into monitoring systems. For this purpose, algorithms are developed based on mechanical models, enhanced by AI components. The objective is to identify precise condition indicators and key performance indicators (KPIs). With these insights, infrastructure and components can be continuously monitored and maintained based on their condition.

Achieving predictive maintenance in three steps: your customized approach

For many, the real challenge lies in implementation. What data should we gather? And, more importantly, how can we extract concrete value from this data?

Our three-step approach makes integrating predictive maintenance into your existing system far more straightforward than you might anticipate. Explore each step by hovering your cursor over it to gain deeper insights:

Noise and Vibration Protection

Noise Control and Vibration Protection in and around Rail Transportation

Construction projects in difficult areas are becoming more common nowadays, especially where the need for densification and the demand for convenient and environmentally friendly mobility intersect. Whether you are building new structures closer to existing railway tracks (>> Learn more) or constructing new railway routes in close proximity to existing buildings (>> Learn more) – these types of projects come with unique challenges.

Drawing on decades of experience in noise control and vibration protection, we offer comprehensive services that include measurement, prognosis, assessment, and mitigation – as a complete package or as individually tailored solutions to meet your specific requirements.

Building Projects near Railway Tracks

Noise and vibration protection for construction projects near railway tracks: Ensuring a high quality of living or working environment in new buildings and protecting the investment from damage

Whether in immediate proximity to railway tracks…

  • a completely new construction area is developed,
  • an already existing building area is to be extended or
  • an existing building is to be renovated,

Noise and vibration protection must be a central component of construction (management) planning for such projects.

A comprehensive acoustic design is necessary from the outset to minimize the impact of noise and vibrations while considering cost-effectiveness. At a minimum, the threshold values defined in the applicable norms and guidelines must be adhered to. If this guarantee cannot be provided, proactive mitigation measures must be developed and implemented, as retroactive measures often incur high costs.

Rail Construction in Residential Areas

Noise and vibration protection during railway construction in residential areas: safeguarding residents and building in the immediate vicinity and ensuring planning and legal compliance for construction authorities

When new railway tracks are planned in developed areas, residents understandably have significant concerns regarding noise pollution. Conversely, construction authorities and operators face potential legal consequences and high costs for retrofitting mitigation measures if threshold values are exceeded. In these cases, noise and vibration protection play a crucial role in two aspects:

  • Immission conflicts regarding sound and vibration protection must be analyzed prior to the construction measures. Through emissions and propagation measurements, as well as determining vibration spread within the building, corridor boundaries of affected areas can be determined. Refining predictions and determining protective and mitigation measures can be achieved through detailed investigations on reference buildings.
  • Comprehensive construction site monitoring is necessary during the construction measures to ensure compliance with all norms and guidelines. This helps prevent excessive disturbance to residents and protects buildings in the immediate vicinity from damages. Additionally, it enables the provision of legal proof for these measures.
  • Vibration and noise predictions also guarantee the adherence to all limits even after commissioning. In the event of (potential) exceedance, the focus is on developing the best possible mitigation measures. Prioritizing the protection of residents and buildings, we also remain mindful of cost-effectiveness.

Multibody Simulation

Better Trains Through Virtual Test Drives with MBS Models


The ideal vision of rail travel? Fast, quiet, comfortable, reliable. To ensure that the passenger notices as little as possible of the rough wind outside the wagon or that goods, for example, reach their destination safely over many years of use, a great deal of development work has to be carried out long before the train comes onto the rails. In addition to comfort, safety, wear, and noise reduction play a central role.

In the development of rail transportation, multibody simulation (MBS) is an indispensable tool. It enables efficient analysis and optimization of various aspects to enhance the quality and performance of rail vehicles and individual components. Through precise MBS models, we can simulate the vehicle behavior under diverse conditions and develop tailored solutions for your specific requirements, thereby improving overall efficiency and effectiveness.

  • Vehicle stability optimization: Evaluating and detecting potentially unstable states to enhance safety and ride comfort.
  • Realistic rail vehicle-infrastructure interaction: Considering the interactions between vehicles and the infrastructure to gain insights into the influence of track irregularities, switches, and crossings. (Wheel-to-rail-contact)
  • Calculation of wind characteristics and reparation of expert assessments for the crosswind verification according to RIL807.04, EN 14067-6 and TSI HS RST.
  • Proof of strength for components within the scope of approval and component analysis for optimal and safe design.
