REPORT NUMBER: FRA-2010-0031
SUBJECT: Positive Train Control
ABSTRACT: In Automatic Speed Control (ASC) territory, LIRR’s PTC system consists of Cab Signaling with ATC and ACSES II. IN non-ASC signaled territories, LIRR’s PTC system consists of wayside ABS signaling and ACSES II. For 2015, LIRR accomplished the following high level elements towards PTC compliance:  Protection against overspeed derailment for critical curve restrictions have been completed using the railroad’s cab signal/ATC system for those segments of the railroad equipped with cab signaling. For the non-cab signal segments, the speed governor of the rolling stock prevents overpeed derailments. Note, the Speonk to Montauk segment of the Babylon Branch is currently in the process of replacing its non-ASC signaling with a new cab signal/ATC system.  Attained a RRIF loan to assist in the funding or its PTC program. The loan obtained by MTA is approximately $1 billion (covering both LIRR and Metro-North PTC implementations.)  Filed necessary waivers with the FCC for use of the acquired IVDS spectrum for PTC.  Had numerous technical meetings with Amtrak to resolve interoperability issues between the LIRR ACSES II system and Amtrak’s. Many of the outstanding technical issues have been agreed-to.  Advanced the project to provide ASC signaling on its non-signaled line from Speonk to Montauk .  Progressed design to provide ASC signaling for its non-signaled line segment from Ronkonkoma to Riverhead.  Filed and received approval from the FCC for PTC radio antenna pole installations for pilot locations.
