The concept of “maintenance limit“ is a innovative way to look at the operation and maintenance of railway system as a single entity to ensure high level of transport system reliability. The concept is based and analogous to safety limit used since many decades. The term maintenance limits is used to show that the maintenance decision should be based on knowledge about degradation rates and taken in such a good time that corrective maintenance can be avoided.
Maintenance limits also implicates that the total cost for maintaining rail and wheel sets combined, should be used as a parameter for maintenance decisions. Currently, JVTC is running
some projects in this area.
