Progress Rail's EMD^® Locomotive Interface Gateway (LIG) is an innovative, integrated design solution that utilizes a state of the art Cat^® A5:N2 controller. The secure OEM platform relies on various ports that interface with proprietary networks for EM2000, Functional Integrated Railroad Electronics (FIRE) and EMDEC^®. These ports also enable the system to communicate with legacy equipment— including Positive Train Control (PTC), event recorders, end of train (EOT) devices, fuel monitors and more. LIG’s robust design off ers a common network architecture for all third party applications, no matter what vintage EMD^® locomotive. Ruggedized for the rail environment, the solution’s 6 Modular Concept Unit (MCU) requires no forced air cooling and meets or exceeds industry EMI standards.

EM2000™ Control System Retrofit Improves Performance and Reliability of Older Locomotives

The EMD^® EM2000^™ Control System is the only microprocessor-based system in continuous use for over 16 years. That history has been supported by a continuous program of product development and enhancement. The EMD^® EM2000^™ is installed in 7000 locomotives in service worldwide. The EM2000^™ Control System Retrofit is a cost-effective solution for upgrading older locomotives to the same full-featured microprocessor technology available in current model locomotives. In addition to managing all critical locomotives operating functions, the EM2000^™ system:

• Increases locomotive residual value
• Improves locomotive availability
• Improves tractive effort
• Lowers life cycle costs

EM2000™ Control System Retro Benefits

Improved Adhesion

• Radar-based wheel slip control increases adhesion performance 33% over older WS10 control systems.
• Employs the same adhesion control logic as current EMD^® 70-Series locomotives.
• Radar system provides true ground speed sensor.
• Creep control improves both high and low-speed adhesion.

Interactive, User-Friendly Display Interface

• Diagnostic fault data is displayed as clear and concise values rather than numeric codes.
• Ability to store up to 600 fault messages.
• Reveals engine performance issues.
• Self-test routines reduce troubleshooting time.
• Data collected before and during fault provides snapshot of operating condition.
• Virtually eliminates NDF trouble reports.

Integrated Automatic Engine Start Stop (AESS™)

• Average savings of 16 gallons of fuel per day per locomotive.
• Reduces idle time and emissions. Parts Standardization
• Commonality of parts with other EM2000™-equipped locomotives in the fleet.
• Reduces inventory maintenance, and operating costs.
• Service personnel are familiar with the technology. Complete Traction Motor Management
• Utilizes the full available TE curve within specified temperature criteria.
• Continuously stimulates traction motor temperature.
• Reduces operating times at higher temperatures to extend traction motor life.
• When temperature criteria is exceeded locomotive is limited to continuous current levels.

Advanced CPU Technology

Complete Locomotive Control – With hundreds of units in service, the SAL™ System is the optimal choice for upgrading older locomotives with microprocessor control of key locomotive systems including:

• Advanced wheel slip and adhesion control for better pulling power
• Engine and cooling system control to maximize fuel efficiency
• Generator control for loading and dynamic brake
• Control of air compressor and other accessory systems
• Traction motor overload protection

Rugged Design Application – Designed specifically for the locomotive work environment, the SAL system uses electronic components designed for severe vibration, shock, and thermal loads. Extremely rugged connectors are used to connect the locomotive control wiring harness to the SAL microprocessor rack system.

Modular Architecture – The control modules are mounted in a shock-resistant rack, allowing the system to be customized for specific locomotive retrofits. Only the necessary locomotive control modules need be installed because the modular enclosure can be easily upgraded in the future.

Pre-Wired Control Panels and Harnesses –The SAL control system can be provided in pre-wired panels that allow and quicker installation. In many applications, the pre-made harnesses include virtually all low-voltage wiring, making setup even easier.

Display System – The color touch screen panel is the operator interface for tracking locomotive performance and troubleshooting. Locomotive and engine performance parameters can be displayed in real-time during operation or load test (on applicable locomotives).

Telematics – An optional telematics package provides locomotive tracking and remote locomotive diagnostics, allowing the locomotive to be tracked from the office through secure internet-based services. Additionally, remote diagnostic services and technical assistance plans are available.

Reliability – The SAL™ locomotive retrofit fundamentally replaces older locomotive control system components and wiring with modern, reliable components. The low-voltage control wiring on the locomotive is replaced with new exane or equivalent wiring. And most of the older relays are converted to modern, solid-state control.

Increased Locomotive Performance — The advanced microprocessor control algorithms and circuits within a SAL™ system result in a typical 8% to 12% improvement in all-weather adhesion. And some locomotives with SAL retrofits have achieved better than 30% adhesion at stall conditions.

On-Board Locomotive Diagnostics for Improved Availability — The SAL display panel offers improved locomotive diagnostics and performance tracking. Maintenance personnel can easily identify and rapidly remedy problems, reducing shop time.

Fuel and Cost Savings – The improved performance of the locomotive allows you to more reliably pull more freight and with greater mission reliability. This can improve overall fuel savings while reducing operating costs. Automatic Engine Start/Stop System (AESS™) – The SAL™ system can automatically shut down the diesel engine rather than wasting fuel with unnecessary idling. By monitoring many parameters, including coolant temperature, air pressures, battery voltages, and more, the engine can be automatically restarted to keep the locomotive in a safe operating condition and ready for service. Installations of AESS systems alone typically result in a 3% fuel savings.
