Article: Optimising wagon and track maintenance: TTCI has developed several new processes and systems that directly address wagon and track maintenance. The main objectives are to reduce the level of dynamic loads exerted on the track structure--reducing the stress state of the railway--and to improve train operating safety.(Workshops & Maintenance)

WHEN it comes to the maintenance of freight wagons and track, an emerging philosophy in North America is to use actual test and detector results to determine when to remove faulty wagons that damage the track and how to identify and correct poor track conditions that cause undesirable vehicle performance.
The evolution of this philosophy can be attributed to the growing availability of detection and testing technologies developed to measure and quantify vehicle/track interaction performance. Bogie (truck) performance detectors (TPD) and wheel impact load detectors (Wild) can identify those wagons that generate high lateral and/or vertical wheel loads. On the ...
