The South Mountain Railroad was authorized by the South Mountain Iron Company legislation in 1864/1865,[2] and company bonds were issued in 1869.[8] The junction with the Cumberland Valley Railroad was laid east of Carlisle near Ashland Cemetery, Carlisle Barracks, and the Carlisle Indian Industrial School.[9]: 2 By June 2, 1874, the railroad had 8 scheduled stops between the terminus and South Mountain Junction;[10] and in December 1875, the railway had sidings of 2.26 mi (3.64 km); 9 passenger, 6 freight, & 3 wood/water stations; and 2 engine houses.[11]
The South Mountain Railway and Mining Company acquired the line in 1877,[2] considered extending the railway line west of Pine Grove in 1880,[12] and "commenced a preliminary survey" in 1881 for a branch southward to Gettysburg.[13] Instead on August 20, 1883; the Gettysburg and Harrisburg Railroad (with the same president, Colonel Jackson C. Fuller) commenced a junction at Hunter's Run for a line to the battlefield.[13] As a result, the South Mountain Railroad's connection near Carlisle at the CVRR's "South Mountain Junction" (named "Carlisle Junction" in the South Mountain RR schedule)[10] was subsequently renamed "Gettysburg Junction".[14] The tracks to Pine Grove Park were used by the first G&H excursion train from Gettysburg on May 28, 1884;[14] and the stop at Laurel Forge was added to the G & H's July 3, 1884, schedule.[15]
The tracks between Mount Holly Springs toward Carlisle were removed c. 1955,[19] and the tracks near Carlisle branching southward from Gettysburg Junction were abandoned c. 1972.[9]: 4 The line's depot and freight station at Gettysburg Junction were subsequently used by the Estep Electric Services Co.[9]: 4 The remaining tracks from Hunter's Run to the Mount Holly Springs area are part of the Gettysburg & Northern Railroad.[20]
