Within the MAJ project (Measurement of Infrastructure from Railway Vehicles), the Swedish Transport Administration (Trafikverket) is exploring new ways to collect and utilize track condition data to enable condition-based maintenance.
The project does not aim to replace traditional methods, but rather to complement them with more frequent and continuous information, directly from vehicles in operation. Trafikverket has long been working to modernize and digitalize railway maintenance – and the collaboration with QTMS is a concrete step in that direction.
The Stockholm metro is one of the busiest railway systems in Sweden. With demands for safety, reliability, and minimised noise, SL has long worked to improve track quality. Initially, SL was looking for a solution to monitor noise levels and identify the factors in the infrastructure that affect the soundscape of the metro.
