49 CFR §299.205

1. (a)Prior to operating its PTC system in revenue service, the railroad must first obtain a PTC System Certification from FRA by submitting an acceptable PTCSP and obtaining FRA's approval of its PTCSP.
2. (b)Each PTCSP requirement under this subpart shall be supported by information and analysis sufficient to establish that the PTC system meets the requirements of § 236.1005(a) and (c) through (f) of this chapter.
3. (c)If the Associate Administrator finds that the PTCSP and its supporting documentation support a finding that the PTC system complies with § 236.1005(a) and (c) through (f) of this chapter and § 299.211, the Associate Administrator shall approve the PTCSP. If the Associate Administrator approves the PTCSP, the railroad shall receive PTC System Certification for its PTC system and shall implement the PTC system according to the PTCSP.
4. (d)Issuance of a PTC System Certification is contingent upon FRA's confidence in the implementation and operation of the subject PTC system. This confidence may be based on FRA-monitored field testing or an independent assessment performed in accordance with § 236.1017 of this chapter.
5. (e)
   1. (1)As necessary to ensure safety, FRA may attach special conditions to its certification of the railroad's PTC System.
   2. (2)After granting a PTC System Certification, FRA may reconsider the PTC System Certification upon revelation of any of the following factors concerning the contents of the PTCSP:
      1. (i)Potential error or fraud;
      2. (ii)Potentially invalidated assumptions determined as a result of in-service experience or one or more unsafe events calling into question the safety analysis supporting the approval.
   3. (3)During FRA's reconsideration in accordance with this paragraph, the PTC system may remain in use if otherwise consistent with the applicable law and regulations, and FRA may impose special conditions for use of the PTC system.
   4. (4)After FRA's reconsideration in accordance with this paragraph, FRA may:
      1. (i)Dismiss its reconsideration and continue to recognize the existing PTC System Certification;
      2. (ii)Allow continued operations under such conditions the Associate Administrator deems necessary to ensure safety; or
      3. (iii)Revoke the PTC System Certification and direct the railroad to cease operations.
6. (f)FRA shall be afforded reasonable access to monitor, test, and inspect processes, procedures, facilities, documents, records, design and testing materials, artifacts, training materials and programs, and any other information used in the design, development, manufacture, test, implementation, and operation of the system, as well as interview any personnel.
7. (g)Information that has been certified under the auspices of a foreign regulatory entity recognized by the Associate Administrator may, at the Associate Administrator's sole discretion, be accepted as independently verified and validated and used to support the railroad's PTCSP.
8. (h)The railroad shall file its PTCSP in FRA's Secure Information Repository at https://sir.fra.dot.gov, consistent with § 299.201(e).
