The Lackawanna Cut-Off (also known as the New Jersey Cut-Off or Hopatcong-Slateford Cut-Off) is a railroad line that was built by the Delaware, Lackawanna & Western Railroad (DL&W) between 1908 and 1911. It was abandoned in 1983, and the tracks were removed in 1984. Partial restoration to Andover, New Jersey, is expected to be completed in late 2018.
When it opened on December 24, 1911, the Cut-Off was considered a "super-railroad", a state-of-the-art rail line, built upon large cuts and fills, and which included two large concrete viaducts that allowed for what was considered high-speed travel at that time. The line was part of a 400-mile (640 km) main line between Hoboken, New Jersey, and Buffalo, New York. The Cut-Off ran west for 28.5 miles (45.9 km) from Port Morris Junction — near the south end of Lake Hopatcong in New Jersey, about 45 miles (72 km) west-northwest of New York City — to Slateford Junction near the Delaware Water Gap in Pennsylvania.
The Cut-Off was 11 miles (18 km) shorter than the Lackawanna Old Road, the rail line it superseded; it had a much gentler ruling gradient (0.55% vs. 1.1%); and it had 42 fewer curves, with all but one permitting passenger train speeds of 70 mph (110 km/h) or more. The Cut-Off also had no railroad crossings at the time of its construction. All 73 structures on the line were constructed of reinforced concrete, which was considered a pioneering use of the material. (The only exception to this would be the bridge over the Morris Canal near Port Morris; that bridge was made of steel on concrete abutments, which would be removed and filled-in after the canal was abandoned in 1924.) The construction of the roadbed required the movement of millions of tons of fill material using techniques similar to those used on the Panama Canal.
The Cut-Off was built and operated by the Delaware, Lackawanna and Western Railroad through a subsidiary, Lackawanna Railroad of New Jersey. It remained in continual operation for 68 years, through the Lackawanna's merger with the Erie Railroad to form the Erie Lackawanna Railroad in 1960, and the EL's conveyance into Conrail in 1976. But Conrail, which had excess east-west routes, ceased operation of the Cut-Off in January 1979 and abandoned the line in 1983. It removed the track in 1984 and the following year sold the right-of-way to two private developers. In 2001, the respective sections in the two states were acquired by the New Jersey Department of Transportation (NJDOT) and the Monroe County Railroad Authority, which now part of the Pennsylvania Northeast Regional Rail Authority (PNERRA).
In 2011, after a nearly three-decade effort to reactivate the line, NJ Transit began construction from Port Morris Junction to Andover, New Jersey (Andover station), a total of 7.3-mile (11.7 km), under the Lackawanna Cut-Off Restoration Project. Construction was later halted due to unresolved environmental issues, but in 2015 NJ Transit announced that it expected to resume construction in mid- to late 2016, and start rail service to Andover in October 2018. Although no specific plans have yet to be announced about the restoration of service west of Andover, a federal study has examined the feasibility of an extension into northeastern Pennsylvania, possibly as far as Scranton, and funding for an update to this study is currently being sought.
The line's origin involves two men who most likely never met: John I. Blair and William Truesdale. Blair built the DL&W's Warren Railroad, chartered in 1851 and completed in 1862, to provide a connection between the mainlines of the DL&W in Pennsylvania and the Central Railroad of New Jersey (CNJ) in New Jersey. But when the Lackawanna-CNJ merger fell through and the Lackawanna merged with the Morris & Essex Railroad in New Jersey instead, the Warren Railroad became part of a circuitous patchwork of rail lines connecting two unanticipated merger partners.
The 39-mile (63 km) route (later known as the "Old Road" after the New Jersey Cut-Off opened) had numerous curves that restricted trains to 50 mph (80 km/h). The bigger operational problem, however, was caused by the two tunnels on the line: Manunka Chunk Tunnel, a 975-foot (297 m) twin-bore tunnel whose eastern approach occasionally flooded with heavy rains; and the 2,969-foot (905 m) single-bore Oxford Tunnel, which was double-tracked in 1869 and reduced to gauntlet track in 1901. As more and more traffic moved over the line, Oxford Tunnel became the Lackawanna Railroad's worst bottleneck.
Truesdale became DL&W president on March 2, 1899, with a mandate to upgrade the entire 900-mile (1,450 km) railroad. Early on, the railroad focused on increasing freight capacity by using larger locomotives and cars, as well as strengthening bridges to handle these larger loads, but by 1905 the railroad was looking to further increase capacity and decrease travel times. By this time, the Old Road was a major operational headache, leading Truesdale to authorize teams to start surveying potential routes westward from Port Morris, New Jersey, to the Delaware River for what would be the railroad's largest project up until that time.
Planning and construction (1905–11)
During 1905-6, 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 28.5 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—especially for freight, but for passenger trains as well. The ruling grade was cut in half from 1.1% to 0.55%. The new line was also built without railroad crossings to avoid collisions with automobiles and horse-drawn vehicles.
Construction officially began on August 1, 1908, with the route 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. The amount of work per mile varied, with Section 3 (David W. Flickwir), which included what would become Roseville Tunnel and the eastern half of the Pequest Fill, apparently having the most. DL&W chief engineer George G. Ray oversaw the project, although 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.
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 so far as to hire a watchman at $40 per month for the duration of the project. Supervisory personnel and skilled laborers stayed in local hotels, boarding houses, or in local farm houses, 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.
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.

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. 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.
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. 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, leading to a decision to abandon the cut and to blast what would become a 1,040-foot (320 m) tunnel instead. Contractor David W. 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.
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.
Stations were built in Greendell, Johnsonburg and Blairstown; the Greendell area was already being served by the nearby Lehigh & Hudson River Railroad in Tranquility. 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 US dollars,. Although exact modern comparisons of cost are difficult, it is estimated that the same project today might cost upwards of $1 billion US dollars.
The first revenue train to operate on the Cut-Off under the new timetable that went into effect at 12:01 a.m. on December 24, 1911, was No. 15, a westbound passenger train that passed through Port Morris Junction at 12:15 a.m. Most Long-distance trains that had previously traversed the Old Road shifted over to the Cut-Off, effectively downgrading the Old Road to secondary status.
The Cut-Off was built to permit unrestricted speeds for passenger trains of 70 mph (110 km/h) (heavier rail that was installed later allowed speeds to increase to 80 mph (130 km/h)). Sidings were built at Slateford, Hainesburg, Johnsonburg, Greendell, Roseville, and Port Morris; about 25% of the route contained additional sidings. With upwards of 50 trains a day, towermen often ordered freight trains to take a siding or even be rerouted over the Old Road. As traffic decreased, Hainesburg, Johnsonburg and Roseville sidings were altered or removed. The remaining sidings remained in use until 1979.
Roseville Tunnel posed occasional problems, especially during the winter with snow and ice buildup. Rockslides were a constant threat west of the tunnel. In recognition of this, a detector fence was installed west of Roseville Tunnel in 1950 to change trackside signals to red if rocks fell. The most serious rockslide to ever occur on the line, however, would take place within Armstrong Cut (just west of Johnsonburg) in 1941, closing the line for nearly a month, and causing trains to be rerouted via the Old Road. The north side of Armstrong Cut was trimmed back to prevent further rockslides.
The Cut-Off was a scenic highlight for passenger trains. Early in the 20th century, the DL&W's woman in white—Phoebe Snow— was featured in a poster that touted the new line and the Pequest Fill. At that time, and into the early diesel era (late 1940s), the Lackawanna Limited was the railroad's premier train. It was later joined by the Pocono Express, the Owl, and the Twilight. While the Lackawanna only operated mainline passenger trains between Hoboken, New Jersey, and Buffalo, New York, passengers could transfer to and from other railroads at Buffalo. For example, the Nickel Plate offered through sleeper service to St. Louis and Kansas City, Missouri, via the Lackawanna.
In 1949, the Lackawanna began modernizing its mainline passenger coaches. The railroad had already begun replacing steam engines with diesels in 1946, starting with mainline passenger trains. The Lackawanna Limited was also modernized and renamed the Phoebe Snow, helping breathe freshness back into a passenger train program that had seen only modest improvements since the 1930s. The Phoebe Snow would run for 11 years as a DL&W train and then as an Erie Lackawanna train from 1963 until November 1966. The Lake Cities, ironically a former Erie Railroad train, became the last regularly-scheduled passenger train on the Cut-Off, making its last run on January 6, 1970.
The only station on the Cut-Off at which mainline passenger trains would stop was Blairstown. Blairstown was also the first stop on westbound trains where passengers were permitted to unboard (i.e. westbound passengers boarding and detraining east of Blaistown were required to use suburban train service instead). This explains why Blairstown was the first stop listed on the destination board at the boarding gate at Hoboken for trains travelling via Scranton. In later years, Blairstown had a somewhat unique facet of operation: any trains arriving after the station agent went home for the night would automatically activate the station platform lights as the train entered the signal block. This practice was abandoned after passenger service ended.
Besides cutting travel time, the Cut-Off required fewer engines to pull eastbound freights up to the summit at Port Morris. For westbound freights, the challenge was keeping trains from going too fast. Initially, no speed limit existed on the Cut-Off, with engineers (both freight and passenger) being expected to exercise "good judgment". By the 1920s, however, most freights were restricted to 50 mph (80 km/h) or less, depending on the priority of the train and the type of locomotive and rail cars. By 1943, 131-pound-per-yard (65 kg/m) rail had been installed on the Cut-Off, which permitted fast freights to run at 60 mph (97 km/h) through the Erie Lackawanna years. After Conrail took over operations in 1976, the speed limit was decreased to 50 mph.
Local freights served customers at all three stations on the Cut-Off. Over the years, Blairstown handled the most local freight. The Johnsonburg creamery, built in anticipation of the opening of the line, served local dairy farmers for years. Another creamery and an ice house were built at Greendell. The final local shipment was shipped in 1978 by Conrail: fertilizer for a customer in Johnsonburg that was delivered to Greendell, as the siding at Johnsonburg no longer existed.
The Cut-Off has seen two accidents during its operation:
- On September 17, 1929, at 6:31 a.m., an eastbound extra freight consisting of 47 cars and a caboose was rammed from behind by a deadhead freight of 24 empty express refrigerator cars and a coach. The engineer at fault was reportedly eating his lunch as his train passed a "restricted speed" signal. He also missed two track torpedoes that exploded as his engine ran over them, and then missed the red signal near the west portal of Roseville Tunnel. His train emerged from the tunnel at 30 mph (48 km/h) and rear-ended a freight train traveling about 11 mph (18 km/h). The impact derailed the trailing locomotive and its coal tender, which the caboose of the leading freight, and two express cars in the trailing freight. The two cars immediately in front of the caboose were also damaged. Four employees were injured.
- In 1960, a freight train carrying automobiles derailed at Greendell.
Three other accidents, which did not occur on the Cut-Off itself, did indirectly involve the line:
- On June 16, 1925, an eastbound passenger special from Chicago scheduled to run over the Cut-Off was rerouted over the Old Road to avoid freight traffic. A storm had washed debris onto the Hazen Road grade crossing three miles (4.8 km) west of Hackettstown, New Jersey, and at 2:24 a.m., the engine and train derailed. Forty-seven people died, most of them scalded by steam escaping the wrecked locomotive. See:
Main article: Rockport train wreck
- At 11:27 p.m. on a misty July 2, 1948, a westbound passenger train, No. 9, derailed at the 40 mph (64 km/h) curve at Point of Gap while going faster than 73 mph (117 km/h). The train had left Hoboken 38 minutes late, and had made up 14 minutes on the schedule by the time it was recorded as having passed Slateford Tower, suggesting that the train may have exceeded the speed limit, particularly along the Cut-Off, during the 75-mile (121 km) trip. The engine (No. 1136, a 4-6-2) and tender overturned and ended upright in the Delaware River. The first car uncoupled from the tender and ended up in the river behind it. The remaining seven cars of the train continued for another 1,735 feet (529 m) down the track. The engineer and firemen were killed.
- Shortly after 6 a.m. on August 10, 1958, a string of a dozen or more cement cars and a caboose broke loose from Port Morris Wye, beginning what was likely among the longest runaways in North American railroading history. The crew of the East End Drill was awaiting orders to move the cars when they began to drift westbound down the grade. Engineless, the cars ran through a switch and onto the eastbound track of the Cut-Off, beginning a 29-mile (47 km) journey that reached a top speed of perhaps 70 mph (110 km/h). Legend has it that a chase locomotive was dispatched from Port Morris in a hopeless attempt to try to catch the cars. Within a half-hour the string had derailed at the sharp (40 mph or 64 km/h) curve at Point of Gap in the Delaware Water Gap, falling into the Delaware River at approximately the same location as the 1948 accident. No one was injured, although an eastbound freight quickly took Greendell siding just ahead of the runaway cars, narrowly avoiding a catastrophic collision. The runaway was blamed on a worker who had not properly set the brakes.
The DL&W was one of the most profitable corporations in the U.S. when it built the Cut-Off. That profitability declined sharply after World War II, leading to the 1960 merger with the Erie Railroad. DL&W single-tracked the Cut-Off in 1958 in anticipation of the Erie merger. The westbound track was removed, leaving a four-mile (6.4 km) passing siding at Greendell and shorter sidings at Port Morris and Slateford. After the merger, most freight traffic shifted to the Erie's mainline through Port Jervis, New York. With the cessation of passenger service in 1970, the Cut-Off became relatively quiet for several years. In 1972, the CNJ abandoned operations in Pennsylvania, causing through freights to be run daily between Elizabeth, New Jersey, and Scranton, using the Cut-Off and the CNJ's High Bridge Branch. (This arrangement with the CNJ would end on April 1, 1976, with the creation of Conrail). As such, when Penn Central closed its Maybrook, New York Yard in 1970, the original reason for using the "Erie side" suddenly no longer existed. As a result, the EL looked to upgrade the "Scranton side", and by 1974 nearly all EL freights had been re-routed to the Scranton Division via the Cut-Off.
After Conrail took over, existing labor contracts kept EL's freight schedule largely unchanged. The railroad replaced many rotted ties, returning it to better physical condition. But Conrail eventually shifted all freight traffic to other routes, citing the grades over the Pocono Mountains and EL's early-1960s severing of the Boonton Branch near Paterson, New Jersey as reasons for moving rail traffic off of the route, leading Conrail to run its final through freights in late 1978 and officially ended service on the Cut-Off in January 1979. Routine maintenance on the line ceased, and the signal system was shut off. Scranton-Slateford freights continued running into 1980 when coal delivered to the Metropolitan Edison power plant in Portland, Pennsylvania, shifted from the Scranton Division to the former Bangor & Portland Railway.
Preservation and service restoration (1979–present)
Preservation efforts began shortly after Conrail ended service in 1979. In spite of an Amtrak inspection train run in November 1979, and attempts to acquire the line by counties in New Jersey and Pennsylvania, the tracks were removed on the Cut-Off in 1984. The right-of-way was sold to two different land developers the following year. The right-of-way was acquired by the State of New Jersey in 2001 (the short section in Pennsylvania was conveyed to the Monroe County Railroad Authority), and subsequent federal studies conducted on the Cut-Off and the mainline into Pennsylvania showed a need for the restoration of passenger service.
Starting in 2011, NJ Transit began relaying track between Port Morris and Lake Lackawanna (about 5 miles (8.0 km) west of Port Morris). By December 2011, about 1 mile (1.6 km) had been installed west of Port Morris Junction to Stanhope, New Jersey. At that time, a Norfolk Southern Corporation's Norfolk Southern Railway provided a track delivery train that brought 7.5 miles (12.1 km) of continuously welded rail to Port Morris. As of 2015, about 4.25 miles (6.84 km) of rail, in three unconnected sections, has been laid between Port Morris and Lake Lackawanna. Most of the right-of-way between Port Morris Junction and the lake has been cleared of trees and debris. Construction on the remaining sections of track is slated to restart in mid- to late 2016, with commuter service to Andover slated to begin in October 2018.

Johnsonburg (station on right, creamery on left) was a flag stop for most of its existence. The station building acted as a construction command post for about a month following a massive landslide within Armstrong Cut (distant background) in 1941. The station closed about a year or two later, and was razed in 2007.
