Start Preamble

In accordance with part 211 of title 49 of the Code of Federal Regulations (CFR), this provides the public notice that by a document dated May 6, 2015, the Long Island Rail Road (LIRR) has petitioned the Federal Railroad Administration (FRA) for approval of its Product Safety Plan (PSP) for its Microlok II Interlocking Controller with Executive Software Version CC3.0. FRA assigned the petition Docket Number FRA-2011-0026.Start Printed Page 31966

The PSP submitted is intended to meet the requirements prescribed in 49 CFR part 236 Subpart H (Standards for Development and Use of Processor-Based Signal and Train Control Systems), specifically, section 236.907 for Microlok II with Executive Software Version CC 3.0.(Microlok II CC3.0). FRA is requiring the LIRR to submit a PSP on Microlok II CC3.0 because Software Version CC3.0 of the executive software incorporates safety-critical modifications and enhancements that did not exist in the previous versions of Microlok II that have been in revenue operations prior to June 6, 2005, and were eligible for exclusion from the requirements of Subpart H.

Microlok II CC3.0 is a processor-based programmable interlocking controller designed for application in safety-critical railway operations. The basic operation of this product is to accept a variety of inputs, perform the user-specified logic that maps those inputs into a series of outputs, and then deliver those outputs to safely operate the various physical components of the interlocking to route trains in a safe manner consistent with standard vital railway signaling practices. The product also incorporates non-vital controls and indications where such features are required.

The LIRR intends to apply Microlok II CC 3.0 as its Vital Microprocessor Based Interlocking Control System (VMICS) at the Harold and Point Interlockings on the LIRR mainline in Long Island City, NY. All tracks through the interlockings have a 60 mile per hour (mph) passenger train speed limit and a 20 mph freight train speed. The operational characteristics include a bi-directional cab signal system with wayside signals within the interlockings.

LIRR maintains that the Microlok II CC3.0 safety critical processor-based interlocking controller uses a combination of intrinsic fail-safety and diversity and self-checking safety assurance techniques to mitigate the effects of random hardware faults. Per LIRR this would allow the Microlok II CC3.0 controller to achieve and maintain a safety integrity level against systematic faults that satisfy the safety requirements of 49 CFR part 236 subpart H.

A copy of the petition, as well as any written communications concerning the petition, is available for review online at and in person at the Department of Transportation's Docket Operations Facility, 1200 New Jersey Ave. SE., W12-140, Washington, DC 20590. The Docket Operations Facility is open from 9 a.m. to 5 p.m., Monday through Friday, except Federal Holidays.
