Input: Question: Is the railroad company that backed the creation of the Beech Creek line still operational? Passage:The company was originally chartered as the Susquehanna and South Western Railroad on August 12, 1882. That company's charter called for a line from Williamsport, Pennsylvania to the southern line of Clearfield County. The proposed line was initiated with the backing of the New York Central Railroad, as part of a far-reaching strategy to ensure access to bituminous coal reserves. The New York Central did not itself extend into the bituminous coalfields, making it vulnerable to action both by the coal operators who mined the coal and rivals like the Pennsylvania Railroad, who carried it. The coal operators of Tioga County, Pennsylvania, some of whom already shipped over the New York Central via the Fall Brook Coal Company's railroad system, faced irrepressible labor troubles and the impending exhaustion of their mines. William H. Vanderbilt, president of the New York Central, responded to the challenge by developing a plan to enter the Clearfield Coalfield, hitherto the exclusive preserve of the Pennsylvania Railroad. The Vanderbilts would provide capital to a syndicate of Tioga coal operators and businessmen of the Clearfield area, incorporated as the Clearfield Bituminous Coal Company, who could acquire coal lands without arousing suspicion. The Fall Brook's rail network, extended down Pine Creek by a paper railroad called the Jersey Shore, Pine Creek and Buffalo Railway, would bring the New York Central's trains to Jersey Shore, on the West Branch Susquehanna River to the west of Williamsport. From there, the Susquehanna and South Western would head west by way of Beech Creek and Moshannon Creek to the vicinity of Clearfield.
