Duryea Yard, formerly Coxton Yard, and sometimes called the Pittston Junction or West Pittston Yard — or as named by its latest lessee, Muller Yard — was built in 1870 by the Lehigh Valley Railroad as a turn around and staging hub to move coal from the North Anthracite Region of Pennsylvania's Coal Regions to Eastern big-city markets when the Railroad successfully established trackage up the Lehigh Valley corridor. The third part of the yard consisted of a bent double-sided ladder traveling first westward, then curving northwards between the River and along the foot of the peak.
