How money moves on this rail, in 12 sourced records: what is final, what can be returned, recalled or refunded, who decides, and what the limits are. A profile belongs to the rulebook, so no reason code list is published on this page.
On a rail fact, every detail line names the section or instrument it rests on and whether that is a rule, a law, operator guidance, or observed practice.
