1 ATTACHMENT TO MEP SUPPLIER SCOUTING OPPORTUNITY SYNOPSIS: LIRR Additional Details and Specifications for Bombardier Serial Transponder JGA Transponders, which are mounted in the gauge of the train tracks, interface with scanner antennas mounted on the underside of trains. Each transponder is configured to convey information to the onboard computer (OBC) specific to that transponder's location and purpose. Information is passed through the air gap to the OBC as a single telegram consisting of a set of data packets that are pre-programmed into the transponder. The communication between the transponder and the on-board scanner antenna is based on inductive coupling. The scanner antenna transmits a signal with a frequency of 27 MHz in order to power up the transponder electronics. The transponder then transmits the pre-programmed information at a rate of 50 khz by means of 4.5 MHz bursts. Transponders are utilized in the rail industry as part of a system for train control applications. There are several types and configurations widely used in Europe and other countries. Specifically in the North East Corridor (NEC) of the United States associated railroads in this area are installing transponders as part of ACSES II to implement Positive Train Control (PTC). The ACSES II System utilizes passive (fixed) transponders located along the route to communicate with onboard equipment as the train passes. The transponders are installed at home signals, distant signals, and at other signal, block point, or cut section locations as needed. The data provided by the transponders allows the onboard ACSES II Subsystem to determine location and direction along the track and provides important data for the territory ahead including permanent speed restrictions and wayside communication information. Transponders shall conform to each of the following requisites: 1. Transponders shall be completely self-contained, requiring no internal batteries, external cables or other sources of energy. Energy furnished to the 4.5 MHz transmitter shall be derived solely from the incoming MHz signal produced by the locomotive-carried scanner. The RF output shall be nil while the transponder is subjected to any other electromagnetic or RF field. 2. Transponders shall not be damaged or degraded when subjected to prolonged energization by a stationary scanner standing directly over the transponder. 3. All material elements of the transponder shall be designed to endure a 20-year service life under the environmental and operational conditions normally encountered, including: i) -40 C to +85 C operating temperature range ii) Humidity 0% to 100% condensing iii) The transponder shall function normally without impairment or degradation at each parameter limit, independently or in combination, specified in AREMA , table , for Class A applications (roadbed). Additionally, the transponder and its mounting appurtenances shall successfully endure, without limitation, any higher level of shock and vibration caused by nearby rail joints, irregular track condition, special track construction, flat wheels, tamping or similar circumstances as may occur during normal railroad operation. iv) Corrosion, fungus and ozone resistant materials throughout.
