Question: How old was the railway that was laid on Wheatfield road in 1894? Passage:During the Battle of Gettysburg, the dirt Wheatfield Road was used by various Union and Confederate troops (e.g., Crawford's Third Division of Pennsylvania Reserves), and Union troops deployed artillery westward to the Peach Orchard using the road. In 1884, the Round Top Branch's wye with double spurs and station was built at the east end of Wheatfield Road, and in 1894 the Gettysburg Electric Railway was laid along a west portion of the road (trolleys also crossed the east end near Round Top Station). In 1895, the Commonwealth of Pennsylvania ceded jurisdiction of Wheatfield Road to the War Department, and in 1900 two cast iron identification tablets were placed to label the road. The Gettysburg Electric Railway tracks were removed from the Wheatfield Road in 1917 and the road was repaired in 1931. The Wheatfield Road was resurfaced with asphalt west of Sykes Avenue in 1933, and completed "from the Rosensteel pavilion to the Taneytown road" in 1940 by the McMillan Woods Civilian Conservation Corps camp.
