Graham Line
The Graham Line (also known as the Guymard Cutoff) is the portion of the former Erie Railroad in New York State from Highland Mills (at about 41°20′35″N 74°07′12″W / 41.343°N 74.120°W) to Guymard (at about 41°25′44″N 74°35′42″W / 41.429°N 74.595°W), built in 1904–1908 as a low-grade freight line. The Graham Line bypasses the original Erie Main Line through Monroe, Chester, Goshen and Middletown. Grade on the Graham Line was not to exceed 0.2% eastward or 0.6% westward, while the original Main Line built in the 1840s had grades up to 1.25%. There were three places where freight trains needed a helper on the old line and none on the new, but just west of the cutoff the grade up from Port Jervis to Guymard could not be improved and remained unchanged as the only place in the area needing a helper. The sharpest curve on the old line was 7 degrees and on the new was 1 deg 30 min. The Graham Line has no grade crossings, a rarity on the Erie. The downside of the improved grade and curvature is that the Graham Line is seven miles longer. Maintaining the desired grade required two notable engineering features, the Moodna Viaduct and the Otisville Tunnel.
