Lubber Run Fill

Lake Lackawanna was created by the removal of fill material for the creation of Lubber Run Fill on the Lackawanna Cut-Off in northwest New Jersey, United States. The lake is fed by Lubbers Run, which was dammed when this section of the Cut-Off was constructed during the years 1908–1911.

Punkhorn Creek is a small stream in the middle of Byram Township, Sussex County, New Jersey. It flows southwest from Lake Bottom, on the north side of and parallel with Amity Road, to Roseville Pond. It is a tributary of Lubbers Run, which is a tributary of the Musconetcong River. It joins Lubbers Run at Lake Lackawanna.

Wharton Fill is one of a number of fills (embankments) on the Lackawanna Cut-Off railroad line in northwest New Jersey. Located between mileposts 51.1 and 51.6 in Byram Township, the fill was constructed between 1908 and 1911 by contractor David W. Flickwir. The fill, which was created by placing fill material obtained by blasting with dynamite or other methods, is about 0.5 miles (0.64 km) long. Most of the material that was used to create Wharton Fill was excavated from the surrounding low-lying area through which Pumpkin Run runs; several of the borrow pits have since flooded and become ponds. Wharton Fill is located on a tangent (straight) section of right-of-way, permitting 80 mph (113 km/h), and is just west of Lubber Run Fill and just east of Roseville Tunnel. This section is scheduled to receive a single track as part of the reactivation of the line, which was abandoned in 1983. NJ Transit rail service is projected to begin no earlier than 2026. Wharton Fill is named for the Wharton Steel Company, from whom this section of right-of-way was acquired.

Roseville Tunnel is a 1,024-foot (312 m) two-track railroad tunnel on the Lackawanna Cut-Off in Byram Township, Sussex County, New Jersey. The tunnel is on a straight section of railroad between mileposts 51.6 and 51.8 (83 km), about 6 miles (9.7 km) north by northwest of Port Morris Junction. Operated for freight and passenger service from 1911 to 1979, it is undergoing work intended to return it to passenger service by 2026.

Hopatcong ( hoh-PAT-kong) is a borough in Sussex County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 14,362, a decrease of 785 (−5.2%) from the 2010 census count of 15,147, which in turn reflected a decline of 741 (−4.7%) from the 15,888 counted in the 2000 census.

Colby Cut (also known as Roseville Cut) is one of a number of cuts on the Lackawanna Cut-Off railroad line in northwest New Jersey. Located between approximately mileposts 51.8 and 52.3 in Byram Township, the cut was constructed between 1908 and 1911 by contractor David W. Flickwir. (During construction, Lackawanna Railroad Chief Engineer, Lincoln Bush, would leave the railroad and join Flickwir's construction company to form the Flickwir & Bush construction company.) The cut, which was created by removing fill material obtained by blasting with dynamite or other methods, is 0.53 miles (0.85 km) long, has an average depth of 45 feet (14 m), and a maximum depth of 110 feet (34 m). The cut was the result of the removal of 462,342 cubic yards of fill material within this section. Colby Cut is named for F.G. Colby, from whom some of the land comprising the cut was acquired, west of what would be Roseville Tunnel. In March 1906, Colby, proposed to Lackawanna President William Truesdale for the railroad to locate a train station for the Cut-Off on his property near what was referred to as Roseville Lake (probably Wright's Pond, which is just east and north of the tunnel). Truesdale had Colby contact the chief engineer, Lincoln Bush, to investigate the idea, but the proposal appears to have gone no further. The cut-off's route was finalized on September 1, 1906. In the months prior, an alternate route was considered (Line "M") that would have proceeded north of where the tunnel would be located, avoiding the need for both the massive cut and the similarly massive Pequest Fill. Line M was rejected because its several-mile, curvaceous sweep to the south near Tranquility, NJ, would be operationally slower.Colby Cut is located on a tangent (straight) section of right-of-way, permitting 70 mph (110 km/h), and is just east of the Pequest Fill and just west of Roseville Tunnel. This section is scheduled to receive a single track as part of the reactivation of the line, which was abandoned in 1982 and the tracks removed in 1984. Colby Cut will be cleared as part of the Roseville Tunnel project by NJ Transit, whose rail service is projected to begin in 2026. The cut will have rockfall mitigation installed as well as improved drainage.
