There are more trains operating today and as a result each train door opens and closes much more frequently. A study by Raildoor Solutions Ltd., shows that door failures now account for over 30% of train delays as, due to safety, the brake systems can not be released on a train until the doors are completely shut and locked.
However little or no real time monitoring of in-service door performance is undertaken, leading to unexpected failures and excessive maintenance of door sets.
In this case study we describe how the Instrumentel Door Diagnostics Unit (DDU) meets the need of rail operators and maintainers by providing a retrofittable, cost effective solution to condition based monitoring of in-service sliding and slam-door sets.
