Title: A "Fit for Use" Analysis as an Approach to Assess Structural Integrity of Running Gear Components
Abstract: Rolling stock is often designed and built to last for a long time, sometimes 30-40 years or more. However, due to new technical possibilities and increasing demands by railroad passengers, fleet owners often wish to upgrade their existing fleet with the newest technology several times during its service life. When the existing fleet is assessed in accordance with the latest standards, fleet owners often have to face the fact that the old designs do not satisfy the latest standards in railroad design. If existing vehicles are required to fulfill the newest standards, or if the 'stand still principle' is applicable but it is not possible to demonstrate that the safety level of the newest designs are equal or better, then the fleet owner will often be confronted with very expensive redesign and modification of those components. This article deals with an example of a 'fit for use' analysis carried out to determine whether it would be safe to deploy existing bogie frames under modified conditions.
