Mountain Top yard
Mountain Top yard or Penobscot yard is a rail yard in Mountain Top, Pennsylvania. It was built by the Lehigh Coal & Navigation Company (LC&N) in response to an 1837 bill authorizing a right of way and was established by 1840, at least as a construction camp for the Ashley Planes, in support of the construction of the Lehigh and Susquehanna Railroad trackage and operations to join the northern Anthracite Coal Region from barge loading docks along the Susquehanna (above and below the Navigations of the Pennsylvania Canal) in Pittston in the Wyoming Valley with the Lehigh Canal.
==Historical backdrop==
Penobscot Knob or Mount Penobscot looming above the local terrain was one of the last terrain obstacles to north-south travel — following after several barrier ranges in the ridge-and-valley Appalachians above the improvements to the Lehigh River allowing water transport over 80 miles inland from Philadelphia's piers — a barrier therefore preventing west to east shipping of coal in the fading days of the canal era, but one in which railroad technology was leaping ahead year by year. LC&N, a high-tech company and major corporation of the 1820s-1870s, had already built the Lehigh Canal and the country's second railroad, the Mauch Chunk & Summit Hill Railroad to ship coal the ten miles of gravity railroad to the loading facility above the head end of the improved Navigations Lehigh River and the Delaware Canal and Delaware River.
