The construction of the Lackawanna Cut-Off, a 28.45 mile (45.9 km) railroad line that shortened a key route for the Delaware, Lackawanna, and Western Railroad, took place in New Jersey from 1905 to 1911.

Planning (1905–1908)

[edit]

During 1905–06, 14 routes were surveyed (labeled with letters of the alphabet), including several that would have required long tunnels. On September 1, 1906, a route without tunnels was chosen. This New Road (Route "M") would run from the crest of the watershed at Lake Hopatcong at Port Morris Junction to 2 mi (3.2 km) south of the Delaware Water Gap on the Pennsylvania side of the Delaware River at Slateford Junction.

At 28.45 miles (45.9 km), the line would be about 11 mi (18 km) shorter than the 39.6-mile (63.7 km) Old Road. The new route would have only 15 curves – 42 fewer curves than the Old Road, the equivalent of more than four complete circles of curvature – which increased speeds and decreased running time – more so for freight, but for passenger trains as well. The ruling grade was cut in half from 1.1% to 0.55%.[1] The new line would also be built without railroad crossings to avoid collisions with automobiles and horse-drawn vehicles.[1]

DL&W chief engineer George G. Ray oversaw the project. Given the size and remote location of the project, Assistant Chief Engineer F.L. Wheaton was assigned the task of overseeing the construction in person.

The project was divided into seven sections, one for each contracting company. Sections 3–6 were 5 miles (8 km) each; Sections 1–2 and 7 were of varying lengths. (Theoretically, to divide the 28.45-mile (46 km) line evenly, the seven sections should have been just over four miles each, but that would have placed the Pequest Fill entirely within Section 3 and the two viaducts within Section 7.) The amount of work per mile varied; the largest share apparently went to David W. Flickwir, whose Section 3 included Roseville Tunnel and the eastern half of the Pequest Fill. (During construction, Lackawanna Railroad Chief Engineer Lincoln Bush would leave the railroad and join Flickwir's construction company, which would take the name Flickwir & Bush.)

Construction (1908–1911)

[edit]

Uncertain national economic conditions in 1907 delayed the official start of construction until August 1, 1908.

To accommodate the labor gangs, deserted farmhouses were converted to barracks, with tent camps providing additional shelter. These workers, many of whom came from Italy and other foreign countries or other parts of the U.S., were recruited and would move on to other projects after their work on the Cut-Off was completed. These workers were viewed with suspicion by the local populace in Warren and Sussex counties, with the town of Blairstown going as far as hiring a watchman at $40 per month for the duration of the project. Supervisory personnel and skilled laborers stayed in local hotels, boarding houses, or local farmhouses, usually at exorbitant rates ($1–2 per day) during the years of construction.

With several thousand men working on the project for over three years, the area all along the Cut-Off, and as far west as Portland, Pennsylvania, benefitted financially.[2]

As many as 30 workers may have lost their lives building the Cut-Off. Most of their names remain unknown because they were registered with their contractor by number only. In 1910, for example, five workers were killed in a single blasting mishap near Port Morris, one of several deadly accidents that involved dynamite. Other workers died in machinery or cable car accidents, or landslides. At least one worker is known to have died of typhoid fever.

Paulinskill Viaduct near Hainesburg is 115 ft (35 m) tall and was the world's largest reinforced concrete structure when built.[2]

The Cut-Off's reinforced concrete structures (73 in all), which consumed 266,885 cubic yards (204,048 m3) of concrete and 735 tons of steel, include underpasses, culverts, and the two large viaducts on the western end of the line.[2]

Some five million pounds (2,300 t) of dynamite were used to blast the cuts on the line. A total of 14,621,100 cubic yards (11,178,600 m3) of fill material was required for the project, more than could be obtained from the project's cuts. This forced the DL&W to purchase 760 acres (310 ha) of farmland for borrow pits.[1] Depending on the fill size, material was dumped from trains that backed out onto track on wooden trestles or suspended on cables between steel towers. During construction, several foreign governments sent representatives on inspection tours to study these new techniques.[2]

The Pequest Fill extended west of Andover to Huntsville, New Jersey. It was at its maximum height 110 feet (34 m) tall and was 3.12 miles (5.0 km) long, requiring 6,625,648 cubic yards (5,065,671 m3) of fill.[1] Armstrong Cut was 100 feet (30 m) deep and 1 mile (1.6 km) long, mostly through solid rock. The line's deepest cut was Colby Cut (immediately west of what would become Roseville Tunnel) at 130 feet (40 m) deep. The tunnel was not in the original plans for the Cut-Off, and in fact much of the cut above the tunnel had already been blasted when in October 1909 unstable anticline rock was encountered,[3] leading to a decision to abandon the cut and to blast what would become a 1,040-foot (320 m) tunnel instead.[4] Contractor Flickwir, whose section included Roseville Tunnel and the eastern half of the Pequest Fill, worked around the clock during the summer of 1911 when construction fell behind schedule.[2]

Stations were built in Greendell, Johnsonburg and Blairstown; the Greendell area was already being served by the nearby Lehigh & Hudson River Railroad in Tranquility.[2] Interlocking towers were built at Port Morris Junction and Greendell, New Jersey, and Slateford Junction in Pennsylvania.

The final cost of the project was $11,065,512 in 1911.[4] Adjusted for inflation, this sum would be $361,842,242 today[5]. But to build such a project today would cost far more; one 1987 estimate put the modern pricetag at $1 billion or more.[6]

Armstrong Cut

[edit]

One of the largest cuts on the Cut-Off, Armstrong Cut was built by Hyde, McFarlan & Burke and sits between approximately mileposts 61.4 and 62.3 in Frelinghuysen Township. Created by removing 852,000 cubic yards of fill material, the cut is 0.89 miles (1.43 km) long, has an average depth of 52 feet (16 m), and a maximum depth of 104 feet (32 m). It accommodates a tangent (straight) section of track, permitting 80 mph (130 km/h).

Armstrong Cut is named for W.C. Armstrong, who had owned most of the land acquired for this cut.[9]

Part of the north side of Armstrong Cut collapsed in 1941, completely blocking the Cut-Off, and causing all traffic to be diverted to the Lackawanna Old Road for a month while the embankment was excavated back. Legend has it that the collapse occurred in the middle of the night and that the freight agent at the freight station (the passenger station had closed the previous year) heard the embankment give way and raised the alarm.[10]

Bradbury Fill

[edit]

Bradbury Fill was built by Waltz & Reece Construction Company between mileposts 49.1 and 49.8 in Byram Township.[11] Made of 457,000 cubic yards of fill material, the 0.75-mile (1.1-km) fill averages 24 feet (7.3 m) high and is up to 78 feet (24 m) tall. It carries a 2° curve that permits 70 mph (110 km/h).

Bradbury Fill is named after Mrs. Delia R. Bradbury, who had owned most of the land acquired for the fill.[12]

Abandoned in 1983, the line is to be reactivated as a single-track line by NJ Transit in 2026.

Colby Cut

[edit]
Colby Cut looking westbound from above the western portal of Roseville Tunnel shown here in 1989.

Located between approximately mileposts 51.8 and 52.3 in Byram Township, Colby Cut was built by contractor David W. Flickwir. Created by the removal of 462,342 cubic yards of fill material, the cut 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). Colby Cut is located on a tangent (straight) section of right-of-way, permitting 70 mph (110 km/h).[13]

Colby Cut is named for F.G. Colby, from whom some of the land comprising the cut was acquired.[14] In March 1906, Colby proposed to Lackawanna President William Truesdale that the railroad should 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.

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.[15]

Jones Cut

[edit]
Early construction on Jones Cut - March 23, 1909.
Blairstown Station, shown here in 1988, is located at the western end of Jones Cut.

Jones Cut, located near milepost 64.8 in Blairstown Township, was constructed by contractor Hyde, McFarlan & Burke by removing some 578,000 cubic yards (442,000 m3) of fill material. Jones Cut is located on a tangent (straight) section of track, permitting speeds of 80 mph (129 km/h). Blairstown Station sits within the cut.[16]

Jones Cut is named for William Jones, who was the principal owner of the land that was acquired for this cut.[17]

Lubber Run Fill

[edit]

Lubber Run Fill, located between mileposts 50.1 and 50.5 in Byram Township, was built by contractor Waltz & Reece Construction Company. It is 0.40 miles (0.64 km) long, has an average height of 64 feet (20 m), and a maximum height of 98 feet (30 m). Most of its 720,000 cubic yards (550500 m3) of fill material was excavated from the surrounding low-lying area. Lubber Run Fill supports a tangent (straight) section of right-of-way that permits speeds of 70 mph (113 km/h).[18]

Lubber Run Fill is named for the Lubbers Run (the "s" was added to the stream's name sometime after the construction of the Cut-Off), which passes under the fill.[19] A dam was built under the fill on the north side of the embankment, creating Dallis Pond, which flows into Lake Lackawanna.

A single track is to be relaid across the fill as part of the reactivation of the Cut-Off. NJ Transit rail service is projected to begin no earlier than 2026.

Vail Fill where it passes over Mt. Hermon Road in the Vail section of Blairstown, NJ. This location was also referred to as Molasses Junction. Note that the underpass design is similar to others on the Cut-Off, which was controversial at the time of construction because some of the underpasses were narrow with a low clearance, and because in winter time horse-drawn sleighs would have a considerable "dead pull" (especially if upgrade) through the tunnel.[20] In this location, which is the tallest part of this embankment, a stream was rechanneled under the road, which itself was realigned with the construction of the Cut-Off. This was done in several locations along the Cut-Off where a road and a stream crossed the right-of-way at approximately the same location.[21][22]

Ramsey Fill

[edit]
Located near the midway point of Ramsey Fill was Johnsonburg Station (right) and creamery, shown here in 1911. In the distance can be seen Armstrong Cut, which produced much of the fill material.
Ramsey Fill at Johnsonburg Station in July 1990. On the right, trees hide the north side of Armstrong Cut, which was trimmed back after the hill collapsed in 1941, temporarily closing the line.

Ramsey Fill, located between miles 60.4 and 60.9 in Frelinghuysen Township, was constructed by contractor Hyde, McFarlan & Burke. The .53-mile (0.85 km) fill has an average height of 21 feet (6.5 m), and a maximum height of 80 feet (24.6 m). It was created with 805,481 cubic yards (615,834 m3) of fill material.

Ramsey Fill is on a tangent (straight) section of track, permitting 80 mph (129 km/h). Johnsonburg Station was located about midway along the fill, just east of Armstrong Cut.[23]

It is named for Stewart W. Ramsey, who owned most of the land acquired to build it.[24]

Slateford Junction

[edit]
Slateford Junction, looking north to the Delaware Water Gap. The Lackawanna Cut-Off (left) and the Old Road (right) converge about 1,500 feet (460 m) past Slateford Tower (obscured by trees, left).

Slateford Junction was a railway junction in the small town of Slateford, Pennsylvania, that operated from 1911 to 1979.

Slateford Junction, where the Cut-Off rejoined the original Lackawanna mainline, sat 28.5 miles (46 km) west of Port Morris Junction. When operations began on December 24, 1911, the junction merged four tracks (two main tracks and two sidings) from the Cut-Off with two from the Old Road.

An interlocking tower at the junction opened four days before the Cut-Off itself. The junction also included a 60-foot turntable, but this saw limited use; it was dismantled in the 1930s and its pit filled in shortly thereafter. The tower closed on January 11, 1951; the switches at the junction became hand-thrown with electric locks.[25][26]

Slateford ceased to function as a junction in 1979, when Conrail ended service over the Cut-Off.

Today, the Pennsylvania Northeast Regional Railroad Authority (PNRRA) owns the surviving tracks at Slateford Junction as well as the right-of-way of the Cut-Off on the Pennsylvania side of the Delaware River. The Delaware Lackawanna Railroad currently operates freight trains at Slateford Junction and over the rest of the PNRRA's tracks.

As of 2022, there are plans to restore service along the Cut-Off via NJ Transit and Amtrak.

Vail Fill

[edit]

Vail Fill sits between mileposts 65 and 65.3 in Blairstown Township, built by contractor Hyde, McFarlan & Burke. The fill was made of 293,500 cubic yards of material, much of which was obtained from nearby Jones Cut, the fill is 0.32 miles (0.51 km) long, an average of 39 feet (12 m) high, and a maximum of 102 feet (31 m) tall. The fill contains a total of Vail Fill is located on a 1° curved section of track, permitting 80 mph (130 km/h).[27]

Vail Fill is named for the nearby hamlet of Vail.[28]

Waltz & Reece Cut

[edit]

This April 1910 construction photo shows a narrow-gauge train hauling fill material to the top of Waltz & Reece Fill. Waltz & Reece Cut is visible to far left; the top of Roseville Tunnel at center, on the horizon.

Waltz & Reece Cut, the deepest cut on the Cut-Off, is 0.68 miles (1.09 km) long, has an average depth of 37 feet (11 m), and a maximum depth of 114 feet (35 m). It was built by Waltz & Reece Construction Company, which removed 822,400 cubic yards of fill material.[29]

Located between mileposts 48.3 and 49.0 in Byram Township, it sits on a tangent (straight) section of right-of-way just west of McMickle Cut and just east of Bradbury Fill.[30]

In 2012, a single track was relaid through the cut as part of NJ Transit's plans to restart rail service no earlier than 2021.

Wharton Fill

[edit]
Wharton Fill shown in 1989 near the eastern portal of Roseville Tunnel.

Wharton Fill, located between mileposts 51.1 and 51.6 in Byram Township, was constructed by contractor David W. Flickwir. It 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.[31]

Wharton Fill is named for the Wharton Steel Company, from whom this section of right-of-way was acquired.[32]

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. [33]
