Port Jervis Line Damage Assessment is Complete; Rail Service Resumes in December

An engineering assessment released Monday calls for massive repairs and 150,000 tons of stone to restore Port Jervis Line train service by the end of the year.

The damage report, presented at the MTA Metro-North Railroad committee meeting, estimated the repair bill at $50 million.

Within two days of the August 28 storm, Metro-North had an alternate bus service in place. On September 19, train service was restored between Port Jervis and Harriman, with bus service provided from Harriman to Ramsey/Route 17. This temporary service plan will remain in effect during the track reconstruction. In all, busing is expected to cost about $10 million over two years.

Metro-North is working with the MTA to identify the necessary funds, including maximum reimbursement from FEMA and insurance.

After the track is reopened in December and train service is resumed, occasional busing will continue in select off-peak periods to allow completion of flood mitigation measures and river bank stabilization that are necessary to protect the railroad’s significant investment in the line. The full pre-storm train schedule will be restored when the second track between Harriman and Suffern is finished in fall 2012.

“We are committed to restoring the Port Jervis Line as quickly as possible. It is an important part of the Metropolitan Transportation Authority’s regional network,” said Metro-North Railroad President Howard Permut. “In the meantime, Metro-North has marshaled the resources of MTA Bus to provide alternative service during reconstruction and Metro-North forces are building access roads to the tracks to literally lay the groundwork for the outside contractor. “NJTRANSIT, Leprechaun Lines and MTA Bus have all been very helpful and cooperative in this crisis,” Permut said.

Metro-North will seek a contractor to rebuild the line, which was ravaged by floods during Tropical Storm Irene last month. An expedited bidding process is planned with a reconstruction contract to be awarded by October 15. Meanwhile, Metro-North forces already have begun to replace stone washed away by the raging Ramapo River, which parallels the track in some locations and crosses under it in others.

An engineering assessment by AECOM has determined that it will take about 150,000 tons of stone – roughly 5,000 tractor-trailer-sized dump trucks – to stabilize the track bed and shore up the river bank for the long term.

Engineers estimate that 90% of the repair work will be replacement of stone washed away by flooding in a 14-mile stretch between Suffern and Harriman.

In all, there are 50 washouts that add up to 2 miles of right-of-way that no longer exists. Fast-moving water overtopped the tracks and scoured away ballast, sub-base and earth to depths of 7 feet. Large sections of track hang in mid-air; some track was grossly twisted out of alignment by the force of the water.

To achieve the goal of restoring train service as quickly as possible, MNR directed AECOM to create a phased rebuilding plan.

The first priority is to restore train service on one track for the four miles between Suffern and Sloatsburg, which was double tracked, and on the 10 miles between Sloatsburg and Harriman, which is a single track. This includes rebuilding the track bed sub-grade, replacing stone in the washout areas, compacting the loose stone and surfacing the right-of-way. Also critical is repair work on the bridges that carry tracks over streams and roads and rebuilding the slopes adjacent to the river.

The initial work will be performed jointly by a contractor working 24 hours a day/7 days a week and by Metro-North Maintenance of Way forces. The contract will be structured with financial incentives for early completion before the end of the year and penalties for delays in completion.

With the slopes shored up, reconstruction of the second track between Suffern and Sloatsburg, repair of the signal system and long-term bridge repairs can be undertaken. Some of this work will have to wait until spring because it can’t be done when temperatures are below freezing.

MTA Real Estate has been working with private property owners to secure easements to allow staging areas for deliveries of stone as close as possible to the points they are needed along the right of way.

“The Village of Sloatsburg has graciously agreed to give Metro-North temporary use of a ball field to gain access to one of the most heavily damaged areas of track. Without this access repairs would take much longer,” Permut said.

Among the findings of the emergency condition assessment:

Surprisingly, the rail, wooden ties and the fasteners that hold them together (screw spikes and spring clip fasteners) were found to be in good condition. Over the past decade, Metro-North’s Track Department had completely replaced the old “stick” rail with 1,500-foot-long sections of continuous welded rail. As a result, the track that has been undermined by washouts resembles bridges dangling in mid-air, but can be restored to proper alignment without replacement.

The signal system fared slightly worse. Water infiltration and erosion of the right-of-way have undermined circuit houses, signal cases and associated battery wells. In many areas, signal and fiber optic cables have been exposed and must be reburied and tested.

Inspections also were performed on 16 bridges, both above and below water. Undermining to abutments and piers was discovered at five bridges and an old stone arch bridge has settled. Damage to bridges was not as extensive as was originally feared.

Debris, including uprooted trees and boulders, covers sections of the track and buried utilities are exposed. Private utility companies have been notified and will be required to inspect the condition of utility and to temporarily reroute lines, if needed, to expedite track reconstruction.

About 2,800 people a day rely on the Port Jervis Line, an extension of NJ TRANSIT’s Main/Bergen Line that is operated under a service agreement with NJ TRANSIT. Infrastructure in the 58.7 miles within New York State is Metro-North’s sole responsibility.

The line is a single track except for the first four miles from the New York-New Jersey state line at Suffern up to Sloatsburg. There was minimal damage in the 45 miles between Harriman and Port Jervis and those repairs were made in time to restore some train service between those stations on Monday, September 19 with 17 trains operated daily, representing 65% of regular weekday train service.

The schedule, which is working well, provides some peak period train service only. Buses continue to provide service for the remaining trains and on weekends. Trains connect at Harriman with express bus service to Ramsey/Route 17 for trains to Hoboken, Secaucus and Penn Station. Additional buses also have been scheduled to operate from Harriman; in the A.M. peak, buses at Harriman leave every 10-20 minutes. This basic schedule will be in effect until train service on the entire line is restored.

Details of the service plan as well as the engineering assessment and a power point presentation on the restoration effort are available at mta.info.

Since the catastrophic damage caused by Tropical Storm Irene, Metro-North’s efforts to rebuild the Port Jervis Line and restore service continue to move swiftly forward. A team of engineers has presented an assessment of the damage to the Port Jervis Line’s track, signal system and bridges in the 14 miles between Harriman and Suffern.

Key assessment findings indicate:

  • Significant damage has occurred in the area of Sloatsburg and Tuxedo.
    • There are 50 washouts that add up to more than 2 miles of right-of-way that no longer exists. Fast-moving water overtopped the tracks and scoured away ballast, sub-base and earth to depths of 7 feet.
    • Large sections of track hang in mid air; some track was grossly twisted out of alignment by the force of the water.
    • River banks have been eroded, encroaching further on the right-of-way.
      This reconstruction work will take significant time and resources to fix before train service can be resumed.
  • Half of the area from Suffern to Harriman sustained little or no damage.
  • Bridge inspections performed both above and under water revealed that the bridges sustained some damage although not as extensively as was originally feared.
  • The signal system fared slightly worse. Water infiltration and erosion of the right-of-way have undermined circuit houses, signal cases and associated battery wells. In many areas, signal and fiber optic cables have been exposed and must be reburied and tested.

Working to restore pre-storm train service by the end of 2011

In order to achieve the goal of restoring train service as quickly as possible, Metro-North has directed the engineering firm of AECOM to create a rebuilding plan which takes place in phases.

Phase Iwill include all work necessary to restore full train service on one track between Harriman and Suffern. Work will include:

  • Building access roads between the material staging areas and the right-of-way (work on this has already started);
  • Rebuilding the track bed sub grade;
  • Replacing ballast in the washout areas, compacting the track bed and surfacing the right-of-way;
  • Performing critical repair work on the undergrade bridges and the track slopes adjacent to the river.

The first phase of this work will be performed by both third party contractors and Metro-North Maintenance of Way forces. The work of these two groups will be fully coordinated.

Third-party contractors will work 24 hours a day/7 days a week. Their contract will be structured with financial incentives for completing work ahead of schedule, and with penalties for delays in completion.

The first phase of work is scheduled to be finished by the end of the year. But it is important to note that this type of construction work is weather sensitive, particularly since the right-of-way is already significantly compromised.

At the end of this first phase, full train service will be restored with the following constraints:

  • Because we will be operating on only one track, there will be some variations in schedule times for off-peak and weekend trains compared to the pre-storm schedule.
  • To allow for the second phase of repairs, periodic off-peak and weekend train outages with bus substitutions will be required.

Phase II of the Port Jervis Line reconstruction will include work required to finish full restoration of the line, with additional flood mitigation to protect this significant investment. This requires:

  • Completing the rebuilding of the second track and track bed between Sloatsburg and Hillburn;
  • Repairing the signal system and returning it to service;
  • Completing bridge repairs;
  • Stabilizing the river bank along the right-of-way, building retaining walls and other flood mitigations.

Completion of this second phase is planned for Fall of 2012. At this point, train service will return to the pre-storm timetable.

We have begun repairs where we have the resources, people, tracks and material. We have started to order the necessary ballast stone. Currently, we are negotiating with landowners for access points for crews, machines and material. We need the cooperation of property owners so heavy-duty earth moving machines, tons of stone, and work crews can access the line and work on a number of places simultaneously to make the repairs as quickly as possible.

The amount of materials required to rebuild is staggering and purchasing has already begun.

  • An estimated 75,000 tons of ballast and other “fill” materials will be needed just for Phase I work to rebuild the sub-grade track structure and make limited repairs to the embankment.
  • Another 70,000 tons is anticipated for Phase II work.
  • This equates to 5,000 tractor trailer-sized dump trucks.
  • Contracts have been executed with four companies to provide ballast and other fill.

Providing Partial Train Service

On September 19, Metro-North took the first step towards restoring train service. We are operating 17 trains daily between Port Jervis and Harriman. This represents 65% of our regular weekday train service, with substitute buses providing service for the remaining trains and on weekends.

These trains connect at Harriman with express bus service to train service at Ramsey/Route 17 to Hoboken, Secaucus and Penn Station. See train/bus schedules.

In addition, our service partner NJ TRANSIT has added semi-express trains that provide more service and shorten the trip for our customers. This is being accomplished using cars and locomotives that we gave to NJT.

We are providing additional parking and bus service at Harriman to accommodate those customers traveling during peak periods to Ramsey/Route 17 and for those traveling to intermediate stations. In the AM peak, buses at Harriman leave every 10-20 minutes in providing significant service from Harriman.

This plan provides you with a more reliable and predictable service during critical travel times. This service plan closely reflects the original train schedule, providing customers with almost the same arrival and departure times at Hoboken.

This schedule will be in effect for the next few months while we continue our efforts to rebuild the 14 miles of the Port Jervis Line between Harriman and Suffern. And we will continue to refine it to provide the best service possible.

In addition, customers can continue to use their Port Jervis Line commutation ticket on the Newburgh-Beacon Ferry or the Newburgh-Beacon Shuttle Bus. Port Jervis Line commutation tickets are being honored for travel on the Hudson Line.

We are also moving ahead with plans to add 100 parking spaces at Beacon Station to accommodate West of Hudson customers who want to travel to midtown Manhattan. The available parking there now has been gradually filling up everyday. Customers from Salisbury Mills Station west to Port Jervis Station with a valid LAZ parking permit can also park at Beacon and Cortlandt Station on the Hudson Line.

We appreciate your patience as we work to rebuild the Port Jervis Line after the catastrophic damage of Irene. We will continue to regularly update you on the progress of our efforts to rebuild the line throughout the project.
