Start Preamble

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 a waiver of compliance from certain requirements of its safety standards. The individual petition is described below, including the party seeking relief, the regulatory provisions involved, the nature of the relief being requested, and the petitioner's arguments in favor of relief.

Denton County Transportation Authority

The Denton County Transportation Authority, Texas (DCTA), seeks a waiver of compliance from certain provision of Title 49 of the CFR. Specifically, DCTA has ordered 11 Stadler Bussnang AG, GTW 2/6 Diesel Multiple Units (DMU), the first of which will arrive in July of 2011, for use on its new “A-train” commuter rail service between Dallas, Texas, and Denton, TX. These vehicles are constructed by European manufacturer and meet European safety standards for crashworthiness and related safety measures. DCTA has submitted two petitions for relief simultaneously. The first petition for relief, the “Base Waiver,” seeks relief from certain requirements of Title 49 of the CFR, particularly part 238, Passenger Equipment Safety Standards (§§ 238.115, 238.121, 238.223, 238 Appendix D Locomotive Fuel Tanks, 238.229, 238.230, 238.305, 238.309); part 229, Railroad Locomotive Safety Standards (§§ 229.31, 229.51, 229.47, 229.71, 229.135, 229 Appendix D Certification of Crashworthy Event Recorder); part 231, Railroad Safety Appliance Standards (§ 231.14); and Part 239, Passenger Train Emergency Preparedness (§ 239.101). The second petition for relief pertains to DCTA's plan to store, test, and maintain these DMU's on yard and out-of-service mainline tracks until FRA considers them for revenue service.

DCTA is building its new “A-train” commuter rail service along a 21.3-mile corridor adjacent to and parallel with Interstate 35 between Dallas, TX, and Denton, TX, along right-of-way-owned by Dallas Area Rapid Transit (DART) and featuring five (5) station stops. DART and DCTA directly operate the mainline and maintain trackage rights agreement with freight railroads for operation on the line. This rail corridor is currently active and is served only by the Dallas Garland and Northeastern Railroad (DGNO), which will continue to provide freight service to customers in the Lewisville, TX, area. DCTA has chosen these Stadler DMU's because DCTA states that they offer an equivalent or higher level of safety, security, and performance to the passengers and crew than conventional FRA-compliant equipment. Initially, DCTA will use FRA-approved and compliant RDC-1 Budd DMU's, leased from Trinity Railway Express (TRE), for a short period of time until FRA considers the Stadler DMU for revenue service. If FRA approves the Stadler DMU for revenue service, and in order to mitigate any potential hazards that may arise from mixing Stadler DMU's with the general railroad system, DCTA will operate its “A-train” commuter rail service during an exclusive passenger period that is temporally separate from DGNO freight trains. This temporal separation may not be necessary once DCTA submits criteria and procedures that provide a technical framework for presenting evidence to FRA in support of a petition for waiver of Tier 1 crashworthiness and occupant protection standards [Alternate Vehicle Technology (per guidelines set forth in the Engineering Task Force report to the Passenger Safety Working Group of the Railroad Safety Advisory Committee)].

Pertaining to the second petition, DCTA will be testing and commissioning the Stadler DMU's while sharing the facility and yard storage tracks at the Operations and Maintenance (O&M) Facility with the leased RDC-1 DMU's. The O&M Facility has been designed to accommodate both the RDC and the Stadler DMU's sufficiently, with storage capacity to hold both fleets concurrently. In order to reduce potential hazards associated with co-mingling these two vehicle types in the O&M Facility, DCTA will operationally segregate the two types by using locked switches, derails, and blue flag protection. Testing on the mainline will be outlined in a Test Plan for FRA's approval and will occur in test zones and during times that no passenger or freight movements occur. DCTA states that this second petition for relief need only be applicable for the time period between FRA's approval of the “Base Waiver” and upon DCTA receiving permission from FRA to begin using the Stadler DMU in revenue service.

Noting that certain provisions in 49 CFR Part 231 pertaining to safety appliances are statutorily required, and therefore not subject to FRA's waiver authority, DCTA also requested that FRA exercise its authority under 49 U.S.C. 20306 to exempt DCTA from certain provisions of Chapter 203, Title 49 of the United States Code because the GTW 2/6 DMU vehicles will be equipped with their own array of safety devices resulting in equivalent safety.

FRA does not anticipate scheduling a public hearing in connection with these proceedings since the facts do not appear to warrant a hearing. If any interested party desires an opportunity for oral comment, they should notify FRA, in writing, before Start Printed Page 7629the end of the comment period and specify the basis for their request.
