Railroad service came to Forest Hill circa 1883, when the Maryland Central Railroad laid narrow gauge track from Baltimore to Delta, PA. After financial difficulties, it emerged as the Maryland Central Railway Company in 1888. Seeking connections with anthracite coal carriers, the company acquired control of the York and Peach Bottom Railroad, and the two lines were consolidated into the Baltimore and Lehigh Railroad Company in 1891. By 1893, financial problems forced another split into the York Southern Railroad and a new Baltimore and Lehigh Railroad Company. In the following years both railroads converted from narrow to standard gauge track. The Maryland and Pennsylvania Railroad, known as the Ma & Pa, was organized in 1901 through the consolidation of the Baltimore and Lehigh and the York Southern railroad companies. Although it never connected to Pennsylvania's anthracite coal mines, its Maryland traffic included U.S. Mail, milk from local farms, freight, and passenger service. Cancellation of the Post Office contract in 1954 effectively ended passenger service as well, and completed state roads further reduced milk and freight business. The former 77.2 winding rural railroad route between Baltimore and York, PA, was then fully accessible by truck and bus service. In 1958, the Ma & Pa ceased rail operations, and the tracks were removed from the railway beds in 1959. Forest Hill's station remains intact as a reminder of rural Harford County's history as an agricultural and natural resources region that serviced the Baltimore area.
