PTC SYSTEM SAFETY ASSESSMENT

49CFR236 Appendix F covers "Minimum Requirements of FRA Directed Independent Third-Party Assessment of PTC System Safety Verification and Validation".   "This  appendix provides minimum requirements for mandatory independent third-party assessment of PTC system safety verification and  validation pursuant to subpart H or I of this  part.  The goal of this assessment is to provide an independent evaluation of the PTC system manufacturer’s utilization of safety  design practices during the PTC system’s development and  testing phases, as required by the applicable PSP, PTCDP, and  PTCSP, the applicable requirements of subpart H or I of this  part, and  any other previously agreed-upon controlling documents or standards."

HCRQ provides this service.

This should come as no surprise; after all, in addition to being system safety and software safety experts, we were the first PTC system safety consultants.

We also provide support for 49CFR236 Appendix D "Independent Review of Verification and Validation".  "This  appendix provides minimum requirements for independent third-party assessment of product safety  verification and validation pursuant to subpart H or subpart I of this  part.  The goal of this  assessment is to provide an independent evaluation of the product manufacturer's utilization of safety design practices during the product’s development and  testing phases, as required by any mutually agreed upon controlling documents and  standards and  the applicable railroad’s (1) Railroad Safety Program Plan  (RSPP) and Product Safety  Plan  (PSP) for processor based systems developed under subpart H or, (2) PTC Product Development Plan (PTCDP) and  PTC Safety  Plan  (PTCSP) for PTC systems developed under subpart I."

Unlike others, perhaps, our intent is not to break your bank in the process of performing this work.  Our intent is to provide you with a thorough, credible, professional assessment.
