This standard specifies the behavior and performance requirements for Y25 bogie type coaching stock bogies, focusing on derailment resistance, curving performance, and stability characteristics. It provides test methods and acceptance criteria for evaluating bogie performance through simulation, calculation, and track testing to ensure safe operation across varying track geometries and speeds. Compliance verification is mandatory for coach manufacturers, bogie suppliers, and infrastructure operators to maintain interoperability and prevent accidents. Accredited testing ensures comprehensive evaluation against standardized criteria, reducing operational risks and supporting evidence-based vehicle certification.
What it measures
Derailment coefficient and safety margin against derailment
Lateral and vertical wheel loads on curves
Curve-climbing behavior and stability
Dynamic response to track irregularities and switches
Forces on bogie frame and guidance components
