Although not required, notice is hereby given that the Federal Railroad Administration (FRA) has received a Notice of Product Development (NPD) from the Union Pacific Railroad Company (UP), pursuant to Title 49 Code of Federal Regulations (CFR) Section 236.913(d)(1) for Phases 1 and 2 of the development of a Communications Based Train Control (CBTC) system. A brief summary of the NPD, including the party submitting it, and the requisite docket number are as follows.

## Union Pacific Railroad Company

UP submitted an NPD of its CBTC system for Phases 1 and 2. The proposed CBTC system is a safety-critical, microprocessor-based system, designed to provide the enforcement of movement authorities and speed restrictions for CBTC-equipped locomotives, and provide the locomotive engineer an assist function to optimize train handling. Phase 1 of the CBTC is a non-vital safety overlay based on BNSF's Electronic Train Management System, previously approved under Docket Number FRA-2006-23687. Phase 2 of the CBTC implements the functionality of Phase 1 using a vital onboard architecture.
