    An inside peek at Red Line's capabilities


    Red Line Engineering is nestled in the Sierra Nevada Foothills, in the small town of Greenwood, Calif. which boasts a population of 926 (US Census Data 2000). Fifteen thousand square feet of manufacturing space occupy a five-acre parcel. It is conveniently located between Highways 50 and 80, and within one hour of Interstate Highway 5 which provides access to major shipping hubs such as San Francisco shipping docks and the Sacramento Delta.

    The area surrounding Greenwood is most known for the 1848 Gold Rush, in which James Marshall first discovered gold.

    The private location of Red Line is conducive to machining high-security national defense products and large scale products for a variety of other industries, while still providing central access to shipping transport.
