Years in development, UP 9900 will be used for operations in northern California ranging approximately 200 miles from its base in Roseville. UP 9900 is the signature unit in a series of 25 locomotives that Union Pacific is analyzing as part of a broad test of various emissions-reduction techniques in northern and southern California. This is the latest step in the company's ongoing effort to design, build and test technologies that reduce emissions."
