Untreated Emissions: NOx nominal * Cummins engines standard, other engines available	Advanced Propulsion System Brand: TMV Control System's TECU controls each traction motor individually Liquid-cooled IGBT controls Touch-screen on-board diagnostics Tractive Effort (Starting) - 33% to 35% Tractive Effort (Continuous) - 23% to 25% ** limited by motor capacity	Electric Brake system Type: Regenerative type brakes up to full force from 0.6 mph to 12.5 mph up to 2200 Hp from 12.5mph to 55 mph Energy dissipation: All energy available for 100% recycling prior to resistors Brake resistor capacity: 2200 Hp continuous

CoGeneration™ Benefits: Power on Demand - Feature utilizes engine shutdown to reduce fuel consumption and excess noise when power demand is low. As Power Demand increases, additional engine(s) comes on-line to provide up to 2100hp (total). Optional power source options may also include battery, third rail or catenary input sources. Cleanest Emissions - Through a combination of clean-burning Tier 2 engines and optional self-cleaning ceramic particulate filters, Hydrocarbon emissions are reduced 97%, NOx reduced by 65%, CO reduced 75%, and Particulate Matter reduced by 93% (See Chart).

Regenerative Dynamic Braking - Allows the use of the brakes (down to 0.6mph) to generate energy that is recycled for use in auxiliary functions like cab heating, fans, air conditioning, lights, radios, refrigerator, and air compressor. Fuel Efficient - Using the most fuel efficient diesel engines in a multi-engine application is part of the estimated 25% reduction in fuel costs. Each engine only operates when it is needed. Highest Rail Adhesion - Using the Traction & Engine Control Unit provides a cab-mounted touch screen display that accesses engine controls and diagnostics. Also controls wheel slip/slide in Power and DB modes based on axle speed sensors. Each traction motor is individually controlled for maximum adhesion.

Smokeless Start - Each engine is started by the generator to a high speed before fuel is introduced. This configuration also eliminates the maintenance associated with normal wear on engine starters and ring & pinion gears. Frame-up Construction - BEC integrates new components onto an “FRA Compliant” new welded frame.
