49 CFR §236.1013

1. (a)For a PTC system to obtain a Type Approval from FRA, the PTCDP shall be filed in accordance with § 236.1009 and shall include:
   1. (1)A complete description of the PTC system, including a list of all PTC system components and their physical relationships in the subsystem or system;
   2. (2)A description of the railroad operation or categories of operations on which the PTC system is designed to be used, including train movement density (passenger, freight), operating speeds (including a thorough explanation of intended compliance with § 236.1007), track characteristics, and railroad operating rules;
   3. (3)An operational concepts document, including a list with complete descriptions of all functions which the PTC system will perform to enhance or preserve safety;
   4. (4)A document describing the manner in which the PTC system architecture satisfies safety requirements;
   5. (5)A preliminary human factors analysis, including a complete description of all human-machine interfaces and the impact of interoperability requirements on the same;
   6. (6)An analysis of the applicability to the PTC system of the requirements of subparts A through G of this part that may no longer apply or are satisfied by the PTC system using an alternative method, and a complete explanation of the manner in which those requirements are otherwise fulfilled;
   7. (7)A prioritized service restoration and mitigation plan and a description of the necessary security measures for the system;
   8. (8)A description of target safety levels (e.g., MTTHE for major subsystems as defined in subpart H of this part), including requirements for system availability and a description of all backup methods of operation and any critical assumptions associated with the target levels;
   9. (9)A complete description of how the PTC system will enforce authorities and signal indications;
   10. (10)A description of the deviation which may be proposed under § 236.1029(c), if applicable; and
   11. (11)A complete description of how the PTC system will appropriately and timely enforce all integrated hazard detectors in accordance with § 236.1005(c)(3), if applicable.
2. (b)If the Associate Administrator finds that the system described in the PTCDP would satisfy the requirements for PTC systems under this subpart and that the applicant has made a reasonable showing that a system built to the stated requirements would achieve the level of safety mandated for such a system under § 236.1015, the Associate Administrator may grant a numbered Type Approval for the system.
3. (c)Each Type Approval shall be valid for a period of 5 years, subject to automatic and indefinite extension provided that at least one PTC System Certification using the subject PTC system has been issued within that period and not revoked.
4. (d)The Associate Administrator may prescribe special conditions, amendments, and restrictions to any Type Approval as necessary for safety.
5. (e)If submitted, an NPI must contain the following information:
   1. (1)A description of the railroad operation or categories of operations on which the proposed PTC system is designed to be used, including train movement density (passenger, freight), operating speeds (including a thorough explanation of intended compliance with § 236.1007), track characteristics, and railroad operating rules;
   2. (2)An operational concepts document, including a list with complete descriptions of all functions that the proposed PTC system will perform to enhance or preserve safety;
   3. (3)A description of target safety levels (e.g., MTTHE for major subsystems as defined in subpart H of this part), including requirements for system availability and a description of all backup methods of operation and any critical assumptions associated with the target levels;
   4. (4)A complete description of how the proposed PTC system will enforce authorities and signal indications; and
   5. (5)A complete description of how the proposed PTC system will appropriately and timely enforce all integrated hazard detectors in accordance with § 236.1005(c)(3), if applicable.
