This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Pursuant to Title 49 Code of Federal Regulations (CFR) part 235 and 49 U.S.C. 20502(a), the following railroad has petitioned the Federal Railroad Administration (FRA) seeking approval for the discontinuance or modification of the signal system or relief from the requirements of 49 CFR part 236 as detailed below.
Applicant: BNSF Railway Company, Mr. Gregory C. Fox, Vice President Engineering, P.O. Box 961034, Fort Worth, Texas 76161-0034.
BNSF Railway Company (BNSF) seeks relief from the requirements of the Rules, Standards and Instructions, Title 49 CFR part 236, Section 236.377 Approach Locking, 236.378 Time locking, 236.379 Route Locking, 236.380 Indication Locking, and 236.381 Traffic Locking, on processor-based systems to the extent that only the following be required every four years after initial testing or program change:
- Verification of the CRC/Check Sum/UCN of the existing location specific application logic to the previously tested version.
- Tests on equipment outside the processor (switch indication, track indication, searchlight signal indication, approach locking (if external)) are verified to the processor's inputs and switch locking is tested from the processor's output to the switch machine.
- Testing of the duration of any timers with variable settings.
Applicant's justification for relief: Many of BNSF's interlockings and control points are controlled by solid-state processor-based systems. The 2-year signal locking tests for solid-state Start Printed Page 18731interlockings required by the FRA place an undue burden on the railroad. Due to train traffic, some large control points can take a month or more to complete the 2-year locking tests. Once a processor-based system has been tested and locking tests documented on installation, re-testing should not be required since the logic continues to operate in the same manor as it did when installed and the operation does not change.
Any interested party desiring to protest the granting of an application shall set forth specifically the grounds upon which the protest is made, and include a concise statement of the interest of the party in the proceeding. Additionally, one copy of the protest shall be furnished to the applicant at the address listed above.
All communications concerning this proceeding should be identified by docket number FRA-2007-27287 and may be submitted by one of the following methods:
- Web site: http://dms.dot.gov. Follow the instructions for submitting comments on the DOT electronic site;

- Hand Delivery: Room PL-401 on the Plaza Level of the Nassif Building, 400 Seventh Street, SW., Washington, DC, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Comments received after that date will be considered as far as practicable. All written communications concerning these proceedings are available for examination during regular business hours (9 a.m.-5 p.m.) at the above facility. All documents in the public docket are also available for inspection and copying on the Internet at the docket facility's Web site at http://dms.dot.gov.

FRA expects to be able to determine these matters without an oral hearing. However, if a specific request for an oral hearing is accompanied by a showing that the party is unable to adequately present his or her position by written statements, an application may be set for public hearing.Start Signature
