P R OD U C T I V I T Y T H R O U G H T E C H N O L O G Y A Major Advance in Train Control Technology LEADER® (Locomotive Engineer Assist/Display & Event Recorder) is a revolutionary new freight train management system designed to improve train handling and yield significant fuel savings. LEADER assists locomotive engineers in reducing fuel consumption while effectively managing trip time and minimizing in-train forces. LEADER’s back-office software utilities help railroads organize and analyze locomotive engineer operating databases to improve both train-handling performance and overall train operating efficiencies.

- 2. On-Board Equipment LEADER® on-board electronicequipment captures, stores, and reports real-time data collected as the train works in normal operation, and includes a cab display that shows train dynamics in real time as the train moves across the territory. Profiler® provides all LEADER functionality without the in-cab display. Both LEADER and Profiler create substantial fuel savings without compromising cycle time or in-train forces. Profiler Profiler is a specific configuration of LEADER that does not incorporate the in-cab display/computer to collect and report train performance data for the purpose of post-trip analysis. Profiler uses GPS and a single board computer (SBC) installed on the locomotive to capture and store data, and an array of communications channels including spread spectrum radio, to transmit LEADER data to a base station. The base station then automatically processes the data for analysis. As with a conventional LEADER installation, the data is available for use at the base station, or it can be delivered to the railroad’s network for analysis throughout the organization. Profiler captures engineers’ performance metrics and real-time operation data to identify the optimal or “Golden Run” best suited to meet the railroad’s goals. Profiler has all the hooks in place to allow it to be upgraded to full LEADER functionality. Off-Board Equipment LEADER/Profiler off-board equipment includes data servers that communicate with the on-board equipment via wayside radio to automatically move data from the locomotive to the railroad computer network. LEADER/Profiler is designed to interface with all common computer systems, and establishes a high bandwidth RF link to the wayside. The off-board equipment also includes playback stations, located within the railroad, that allow the user to manually or automatically process performance data to profile the operation, find trouble spots, or ensure proper adherence to operating policy. Radio Communication LEADER radio communication employs state-of-the-art spread spectrum radio technology to communicate data between locomotives when on the move, and from the locomotives to LEADER base stations when the locomotives enter a base station zone. All data is transmitted automatically without manual intervention. Fast Payback Payback on the investment for a full LEADER system is typically less than two years. The energy- efficient train handling provided by LEADER results in very substantial fuel savings, less wear and tear on track, couplers and knuckles, wheel sets, and brake shoes—which further reduces operating and life-cycle costs. LEADER enables the engineer to better manage in-train forces, which reduces lading damage and subsequent claims. In addition, accident insurance costs associated with train separations and derailments are reduced, while safety is increased, lowering insurance and liability costs. And LEADER provides the data required for creating more cost- effective scheduling and operating procedures— increasing railroad efficiency and competitiveness. Reliable Accuracy Drawing from a track database of 120,000 miles, LEADER provides predictive algorithmic calculations of in-train forces that are over 95% accurate, as demonstrated in field tests. TDS’ train dynamic track profiles are the most accurate in the industry, providing information that defines the “Golden Run” for any type of train service. Responsive NYAB Support Every LEADER system is backed by the expert engineering and customer service of the Train Dynamics Services Group in Ft. Worth, Texas, and the superior New York Air Brake field support delivered from locations across the United States and Canada. LEADER® Dynamics Models Back-Office® Tools Advanced Event Recorder Playback Driver Assist Based On Golden Run Analysis Databases Consist Track Profile GPS Human- Machine Interface Profiler® Analyzed Run Data Run Data Raw Data: Sensor Array or LSI On-Board Storage Profiler provides all LEADER functionality without the in-cab display. The system includes on-board and remote (off-board) equipment, in either of two available configurations. LEADER In-Cab Display The rugged, sunlight-readable LEADER cab display provides the engineer with a wide range of information including track topology, train trajectory, real-time status of trail and remote locomotives in the consist, brake system status, and in-train forces. LEADER software applications are highly integrated with existing on-board display/computers, saving space and cost as well as improving system reliability, and can be installed as an overlay with NYAB computer platforms. Playback System The LEADER playback system assembles the logfiles from all the locomotives in the train automatically, and identifies the train’s correct location for analysis. The integrated GPS system allows LEADER to always know where the train is. On-Board Capabilities/Functions LEADER operates in an information-only mode, or in a proactive-assist mode, by providing recommended throttle and brake settings. In either mode, it provides information that will save fuel and improve safety. LEADER also functions as an event recorder, and its underlying simulator technology easily allows its real-world data to be downloaded for in-depth study and replay on a simulator—ideal for engineer training and incident investigation. LEADER integrates input from the EOT device, trail and remote units, and any microcomputer-based system, including distributed power and ECP brake systems. Shared Knowledge • Enable all your engineers, including the very best, to become even better. • Set operational goals based on a complete and thorough understanding of how your operation works today, and then monitor to ensure that your goals are being achieved. • Monitor engineer performance from a road foreman’s desk with regular, automatic analysis that enables proactive management of negative trends before they become problems. • Understand common, objective measures of train performance shared with the road foreman and/or engineer. The LEADER playback screen features control (bottom panel) and status (far right) windows adjacent to the LEADER display. All data is collected and processed by LEADER/Profiler without manual intervention.
