Cracked

"Cracked," in railcar inspection and repair, describes a component that has fractured but whose pieces all remain physically connected. The metal has begun to fail and a crack is present, but the part has not separated into two or more loose pieces. A fracture that has fully separated is instead reported as broken.

Why the Distinction Matters

Cracked and broken are both fractures, but the rules treat them as distinct conditions because they describe different stages of failure. A cracked component still holds together, while a broken one has lost continuity entirely. Drawing the line precisely matters because the term applied to a defect drives how the car is handled - whether it can move, whether it must be repaired first, and how the defect is documented.

Interchange and Repair Implications

A crack in a safety-critical component is a defect that generally must be addressed before the car continues in normal service, since a crack can grow under load until the part breaks. When a cracked component is found, the car may be set out for repair, and a crack discovered at a handoff can support a rejection at interchange. The repair is recorded and billed to the responsible party through Car Repair Billing. Inspectors apply the term carefully, reserving "cracked" for fractures whose pieces remain connected and "broken" for those that have separated.
