QTMS is a service that helps to digitalise condition-based maintenance of railways by automatically measuring track condition parameters and generating insights. The aim is to reduce traffic disruptions through increased knowledge of the relationships between asset degradation and the effect of maintenance actions. 

By frequently measuring and analysing changes in track condition over time, QTMS enables track owners to identify locations that are at risk of causing traffic-impacting failures - and thus introduce timely preventive measures. 

For example, QTMS can help map and understand impact relationships such as how the elevation is affected by ground frost, which is dependent on site-specific soil properties. These insights allow for the creation of action plans that are more site-specific and effective. 

"When we started exploring the possibilities of digitalising the maintenance of our railways, QTMS stood out as the most interesting solution"

Focus on preventive maintenance and reducing traffic disruption

QTMS is designed to reduce the need for traffic disrupting corrective maintenance and improve the quality of preventive maintenance. The service focuses on measuring and analysing track condition parameters defined according to the standard (SS EN 13848) - the same parameters already used in measurement and maintenance. 

The insights gained from QTMS are directly linked to the most common track defects causing traffic-affecting remarks. By analysing trends and rates of change, the track owner can quickly prioritise interventions at locations where limits are close to being exceeded or where anomalies have already been identified.

Impacts and benefits

Using QTMS to complement measuring trolleys brings the following benefits: 

  • Reduced need for manual inspection: QTMS enables continuous measurement, reducing dependency on physical inspections and freeing up resources for more strategic actions. 

  • Improved accuracy in maintenance planning: frequent data collection identifies trends and changes over time, providing a better basis for prioritising interventions between the more detailed gauge car inspections. 

  • Reduced inspection citations: Insights from QTMS enable rapid action to be taken at non-conformity sites before they escalate into traffic-impacting problems. 

  • Reduction of traffic disrupting corrective maintenance: By acting on real-time data, the track owner can avoid unexpected failures and improve railway reliability. 

QTMS provides a continuous overview of the condition of the track and acts as a continuous update between the detailed inspections of the measuring wagons. Together, these technologies create a robust strategy to optimise both preventive and corrective maintenance, contributing to a more sustainable and reliable railway infrastructure.
