the saco valley railroad was a short-lived logging railroad that followed the dry river in new hampshire. the short line extended northward from a junction with the mountain division. the slope is a steep one and the railroad had to stay very near, or even between the banks of the dry river on wooden trestlework. washouts were a regular occurrence. the saco valley railroad only ran for six years before the area was logged out. without maintenance, all trace of the line was washed away by 1907.
