 In 1933 EMC designed the power setups for the "Zephyr" and "M-10000" streamliners, a breakthrough in the power and speed available with their propulsion systems.The "Zephyr" used the first major product of the new GM-Winton venture, a 600 hp, eight cylinder version of the Winton 201A Roots blown, uniflow scavenged, unit injected, 2-stroke diesel engine.As the Budd and Pullman-Standard companies entered contracts to build more diesel-powered streamliners, they became major customers for EMC.
