Newcastle, Wyo., on the edge of the Black Hills, was founded in 1889 when the Chicago, Burlington and Quincy Railroad arrived in northeastern Wyoming. Newcastle sprang up where a spur left the main line of the Burlington to head seven miles northwest to the coal mines at Cambria. The Burlington –now, after its merger with the Santa Fe Railroad, the BNSF—is still a major employer, along with a local oil refinery, hospital and school district, and businesses that serve tourists.
