          - [Waiver Petition Docket Number FRA-2006-26029] 

In accordance with Part 211 of Title 49 Code of Federal Regulations (CFR), notice is hereby given that the Federal Railroad Administration (FRA) has received a request for temporary waiver of compliance with certain requirements of its safety standards. The individual petition is described below, including the party seeking relief, the regulatory provisions involved, and the nature of the relief being requested. 

## Alaska Railroad Corporation 

                    In September 2006, the Alaska Railroad Corporation (ARRC) submitted a temporary waiver petition to support field testing of its processor-based train control system, identified as Collision Avoidance System (CAS), pursuant to 49 CFR 211.7 and 211.51. The regulatory relief sought by ARRC was for development testing and demonstration purposes only. This waiver request was conditionally approved by FRA on February 22, 2007. All information submitted in conjunction with ARRC's previous waiver petition can be found in Docket Number FRA-2006-26029.                           ( print page 52458)    

ARRC has now submitted a new waiver petition requesting modification to the previously approved regulatory relief. In the petition, ARRC specifically seeks relief from the following regulations: 

1. Regulatory relief from 49 CFR 236.514 (Interconnection of cab signal system with roadway signal system); and

2. Modification to the previously approved regulatory relief from 49 CFR 236.11 (Adjustment, repair, or replacement of component) to specifically exempt the wayside interface that was installed to support CAS. 

Interested parties are invited to provide written views, data, or comments pertinent to FRA's consideration of the ARRC's request for waiver of compliance.
