Gov. Larry Hogan and other political and business leaders Tuesday toured the Hitachi Rail factory that’s being built in Washington County. “The job creation potential and associated economic benefits are an absolute game-changer for this region and for the entire state,” the Republican governor said in remarks before the tour. “This project is further proof that the Hagerstown region is a major logistical center for transportation with unparalleled connections to the northeastern United States.” Hitachi also unveiled the final design of the $70 million factory, which will employ about 460 people and help sustain a total of 1,300 jobs in the region. The 307,000-square-foot facility is being built at the west end of Halfway Boulevard, which the county plans to extend to Greencastle Pike (Md. 63). The 41-acre site also will include an 800-foot test track.
