In accordance with § 236.913 of Title 49 of the Code of Federal Regulations (CFR), notice is hereby given that the Federal Railroad Administration (FRA) has received an informational filing from the Norfolk Southern Railway (NS) to permit field testing of the railroad's processor-based train control system.

## Norfolk Southern Railway 

NS has submitted an informational filing to FRA to permit field testing of the railroad's processor-based train control system identified as Optimized Train Control (OTC) Positive Train Control (PTC) System. The informational filing addresses the requirements under 49 CFR 236.913(j)(1). 

Specifically, the informational filing contains a description of the NS OTC PTC product and an operational concepts document pursuant to 49 CFR 236.913(j)(1). The NS OTC PTC system is designed to assist train crews in situational awareness, prevent authority limit and over-speed violations, provide open switch protection in non-signaled Track Warrant Control territory, and to prevent equipped trains from entering the limits without authorization of on-track authority granted to employees. NS desires to commence field testing on or after September 1, 2008, or as soon as practicable thereafter, contingent upon FRA's acceptance and approval of their informational filing. 

                    Interested parties are invited to review the informational filing and associated documents at the DOT Docket Management facility during regular business hours (9 a.m.-5 p.m.) at 1200 New Jersey Avenue, SE., Room W12-140, Washington, DC 20590.
