Broken

"Broken," in railcar inspection and repair, is a mode of failure defined in most contexts as a complete separation into parts. A component is broken when it has fractured all the way through so that its pieces are no longer joined to one another. This is distinct from a cracked component, which has fractured but whose pieces remain physically connected.

Why the Distinction Matters

The difference between broken and cracked is not just descriptive - it determines how a defect is handled. Both are fractures, but a broken component has lost its continuity entirely, while a cracked one has not yet fully separated. Inspection and repair rules treat these as separate conditions, each with its own implications for whether a car may continue in service and how the defect must be addressed.

Interchange and Repair Implications

A broken safety-critical component generally makes a car unfit to move until it is repaired. When such a defect is found, the car may be set out of the train for repair, and if discovered at a interchange handoff it can be the basis for a rejection at interchange. The repair is recorded against the car and billed to the responsible party through Car Repair Billing. Because the term carries this specific consequence, inspectors apply it precisely: a component is reported as broken only when it has actually separated into parts.
