The branch ran southward from the terminus of the railroad's main line (its junction with the Hanover Junction, Hanover and Gettysburg Railroad north of Meade School), west of the school and St. Francis Xavier Cemetery, across the field of Pickett's Charge, south of Cemetery Ridge, east of Weikert Hill and Munshower Knoll, and through Round Top to a point between Little Round Top's east base and Taneytown Road.

[17] In 1902, Camp Lawton was headquartered at The Angle with its telegraph and telephone office at the Emmitsburg Rd "junction of the steam and electric roads near the Codori buildings".

[18] Through October 1914, a combination arsenal and commissary along the Round Top Branch was used for Pennsylvania National Guard camps at Gettysburg.

[19] A special platform on the branch was built for 1913 Gettysburg reunion veterans to disembark directly into their camp[12] on the west side of Emmitsburg Road;[citation needed] after addressing the veterans, President Woodrow Wilson departed the Great Camp in his private rail car via the branch.

[22] Except for special occasions (such as a trip by Bethlehem students in 1958),[23] Reading passenger service to Gettysburg ceased in 1941[24] and an application to abandon the Round Top Branch was made in 1942[1] (the rails were removed and a few artifacts remain in place).
