 Work continued on the more difficult middle segment, which required heavier grading to climb along the slopes of Second Mountain and enter Stony Valley at Fishing Creek Gap.On March 13, 1854, a second railroad, the Auburn and Port Clinton Railroad, was chartered for the project.This would connect the D&S at Auburn with the Allentown RR at Port Clinton, running parallel to the Reading main line along the Schuylkill River.
