Railroad personnel can submit reports to NASA C3RS when they are involved in, or observe an incident or situation in which railroad safety might be compromised. All report submissions are voluntary. Reports sent to NASA C33RS are held in strict confidence. C3RS de-identifies all reports before entering them into the safety report database.

All personal and third party references (carriers, employees mentioned, etc.) are removed or de-identified. Dates, times, and related information which could be used to infer an identity, are either generalized or eliminated.
