In the past, we had only visual inspections in place, and no reliable statistics or measurements connected to individual vehicles," says Gunnar Ivansson, a consultant at LearningWell AB, which helped the Swedish Transport Administration develop the monitoring system. "By identifying each vehicle with RFID and obtaining exact measurements, it is now possible to detect problems early. There is a huge cost savings related to avoiding damage to tracks, and there is a diminished risk of a derailment due to an equipment failure."
