The Walkersville Southern Railroad (reporting mark WS) is a 6.72 mile (11 km) heritage railway in Walkersville, Maryland. running from MP 60.0 south of Woodsboro, MD to MP 66.72 just north of the intersection of Route 26 and U.S. Route 15 near Frederick, Maryland (Using PRR Milepost data where mileage ran north to south, and Frederick was at MP 69.0). History The Walkersville Southern Railroad runs track and structures originally built by the Frederick and Pennsylvania Line railroad. This railroad ran from Frederick, Md to the Pennsylvania-Maryland State line, or Mason–Dixon line near Kingsdale,PA. Chartered in 1867, the railroad started construction in 1869 and cost $868,687.50 ($=). It opened October 8, 1872 and was subsequently leased to the Pennsylvania Railroad from January 1, 1875, and in July of that year, PRR formed a new division, the Frederick division to operate the rail line. In the spring of 1896, it was liquidated in a judicial sale to the Pennsylvania Railroad for 10% of its 1896 book value. Pennsylvania reorganized the railroad in December, 1896 as the Frederick and Northern Railroad Company. In March 1897, this new company was itself merged with other Pennsylvania-controlled railways (Littlestown Railroad and the Hanover and York Railroad Company) into the Hanover and York Railroad Company, chartered under the general laws of Pennsylvania and Maryland. In 1914, this railroad and the newly built Central Railroad of Maryland were then merged into the York, Hanover and Frederick Railway Company which remained a wholly owned stock subsidiary of the PRR into the creation of the PennDel company on December 31, 1953 and then the Penn Central merger in 1968 and then bankruptcy in 1970. The Frederick and Pennsylvania Line segment was transferred to the State of Maryland in 1982 for unpaid taxes. One of the industries that fed the railroad during its earliest time of operations was the Lime Kiln in Walkersville. This was among the industries that fueled the need of the railroad, to ship fertilizer to farmers in and around the Walkersville region. The Frederick Secondary remained in the control of the Pennsylvania Railroad even into the creation of the Penn Central Railroad. The Walkersville Southern operates on part of the Penn Central's Frederick Secondary. Penn Central, then in bankruptcy, sold the line to the state of Maryland in 1972 after Hurricane Agnes washed out the bridge over the Monocacy River. The line remained dormant until 1980
