Worker Rescued from Chest-high Mud


As reported by numerous media outlets, a construction worker on the Second Avenue Subway project was seriously hurt yesterday evening after he became trapped in chest-high mud between 95th and 96th streets deep under Second Avenue.

According to the news website DNA.info, 155 first-responders raced to the scene at about 8:30 p.m. on the evening on March 19th to begin a major operation to rescue the worker. Some four hours later, the half-submerged man was finally freed from the mud and transported to New York-Presbyterian/Weill Cornell Medical Center with hypothermia.

Based on an earlier conversation I had with a contractor, it seems the worker may have became stuck in a soil material composed of varved silt -- or as it is commonly called, "bull's liver", by some contractors in New York City. Varved silt was deposited in the New York City area by ancient glacial lakes that once existed in the region.


Earlier today, the MTA posted on their Flickr page a set of stark images that were taken after the incident. A few of these images are posted below.

100 Years Ago on Second Avenue


ELEVATED RAILROAD HEARINGS CALLED
New Lines and Third-Tracking of Interborough
and New B.R.T. Routes Come Up for Approval

This was the headline in the
New York Times on January 3rd, 1913.

So you ask, what's this all about?

Around this time period, 100 years ago, the Interborough Rapid Transit Company (IRT) was pressing the New York Public Service Commission for approval to add a third-track, for express service, on its Second, Third and Ninth Avenue elevated railway lines in Manhattan.

In this posting we'll take look at the IRT's efforts to add a third-track to the Second Avenue Elevated Line -- nearly 100 years ago.

Before we get to that, let's look at some of the history of the Second Avenue Elevated, which operated from 1882 until 1942.

The Metropolitan Elevated Railway Company began initial construction of the Second Avenue Line on February 24, 1879.

At that time, the population of New York -- (then comprised only of Manhattan and parts of the Bronx) -- was about 1.2 million.1


Map and Guide of the Elevated Railroads of New York City
H. L. Latimer, 1881


The company's design (for the Second Avenue line) called for sufficient space to lay three elevated tracks. However, during the initial build, only two tracks were laid.2

It was reported that initial construction of this line, as well as the other "el's" as they are sometimes called, was not without conflict. There were reportedly long battles over rights to air, property, light and access.

An article in Scientific American in October 1879 described in some detail the early construction efforts at that time,
"For a distance of four miles a perfect network of gas, water, and sewer pipes was encountered, making a special plan necessary for each foundation.

The most troublesome pier of all was that at 108th street, where the center of the pier was directly over a large sewer which received two large inlets within the area of the foundation, and the problem was further complicated by the presence of a 30 in. gas main and two croton water pipes.

Though twenty piles were enough to carry the piers under ordinary conditions, it was necessary at this point to drive 82 piles to get proper bearings, and to use 130 cubic yards of concrete, a massive cast iron bed plate, and 80,000 bricks.

In all nearly a thousand tons of iron are said to have been required in arching over pipes in the 2,400 foundations for piers.

In making these foundations 60,000 cubic yards of rock had to be blasted and removed under the most exacting conditions, and 80,000 cubic yards of earth.

Five steam pile drivers were employed in driving 300,000 lineal feet of piles for foundations in marshy places.

The engineer in charge gives the amount of lumber used in the piers at 800,000 feet board measure, there were required, in addition, 50,000 cubic yards of sand for mortar, 80,000 cubic yards of broken stone for concrete, 70,000 barrels of cement, and 21,000,000 bricks.

One contract for iron for the superstructure called for 80,000,000 pounds."3

The first section of the Second Avenue Elevated, from Chatham Square to 65th Street, was opened for service on Monday, March 1st, 1880 at 5:30 a.m - amazingly just one year after construction had begun.

When the line opened, none of the stations were yet complete. the New York Times reported that "the ticket-sellers yesterday sat on temporary pine boxes, resembling the boxes which ornament the street corners on election day."4

By August 16, 1880, all structures and tracks were ready for operation, and trains were operated from South Ferry to 127th Street, then the extreme north limit.5

By 1884 the Manhattan Railway Company had taken over the Second Avenue Elevated when the Manhattan Railway, Metropolitan Elevated and New-York Elevated companies were merged into a single company.

Then in 1903 the IRT secured control of the elevated railway lines in Manhattan when it leased all of the franchises and property of the Manhattan Railway Company. The term of IRT's the lease was 999 years.6

The elevated line was operated using steam powered locomotives until the turn of the century when efforts to operate electric trains were introduced.

The first regularly scheduled electric train service operated in late 1901. By September 2nd, 1902, all of the steam powered locomotives had been removed from service on the elevated line.

::

In early 1914 a final decision was made to add a third track to the Second, Third and Ninth Avenue elevated railroads in Manhattan. Construction contracts for the work were awarded to three firms: Terry & Tench Company, Snare & Triest Company, and the T. A. Gillespie Company.

With an additional track, each line would be able to offer one-way express service during the rush hour periods.

Third-tracking work on Second Avenue began in 1914 and was completed in early 1916, without the need to shut down the existing service on the line.

The express stations on the Second Avenue Line were constructed at the City Hall, Chatham Square, 14th, 42nd, 86th and 125th Street stations.

In some locations, the construction of express stations was found to be quite difficult due to the narrowness of certain streets.

To overcome this problem, so-called "hump" stations were constructed at some of the planned express station locations. This resulted in the express track being elevated above the local tracks, for example at the 86th Street station, and access to the express platform was provided via the local platforms.

The images that follow were taken during 1914 and 1915. They appear to be construction progress photos that were taken to document the work of the contractors.

At some point, the images were turned over to the New York Transit Museum, which is where I found them during a recent visit to their archives.

At this location, the contractor is constructing new outside platforms at the 92nd Street station. Once this was done, the existing wooden center-island platform, which is visible in this image, would have been removed to make room for the new third track.

The buildings to the left of the station were part of George Ehret's Hell Gate Brewery and the Jacob Ruppert Brewery that once operated in this neighborhood.

At their peak, the two breweries owned almost three dozen buildings between Third and Second Avenues and 90th and 94th Streets. The Hell Gate Brewery and Ruppert Brewery ceased operations in 1929 and 1965 respectively.7

The new stairway (shown above) at this station is being built to provide access to the new outside platforms.

Look carefully and you can see two street cars. The somewhat blurry car in the foreground would appear to be a horse drawn car, which is commonly referred to as a horsecar. Horsecars were still in use in parts of New York City as late as 1917.

The Second Avenue Elevated remained in service until the early 1940s.

The last run over the full length of the line departed South Ferry at 11:16 p.m., on Tuesday, June 11, 1940. It arrived at 129th Street, its final destination, at 11:51 p.m.8

The portion of the line south of 60th Street remained in service for two more years, until June 13, 1942.  It was reported that there were two hundred passengers on board the six-car train that pulled out of South Ferry station, on the "last run" of the Second Avenue El, that evening.9

When the Second Avenue Elevated line was discontinued in 1942, some of its coaches were acquired by the Richmond Shipyard Railway in California.

One of these coaches, No. 561, survives to this day and can be found, in operable condition, at the Western Railway Museum in Suisun, California.

According to the Western Railway Museum, the car was built in 1887 as Manhattan Railway Car No. 844 by the Gilbert Car Company of Troy (Green Island), New York. In its early days, it was pulled by a steam engine.

When the elevated lines in New York were converted to electric power, Car 844 was subsequently equipped with electric propulsion equipment.

Seasonal Snapshots on the Avenue


As I've done in past years in December, I recently took a walk down Second Avenue to look for signs of the holiday spirit amid ongoing construction.

The pictures that follow were taken on two different Saturdays. They offer the viewer a collection of fall and early winter snapshots of the scene on Second Avenue.



12/8/12
93rd Street, SE corner - looking W

Amid the springy colors above, a Christmas tree is visible through the construction fencing.



10/27/12
97th Street - looking S

The contractor at this location is in the process of excavating material (earth and rock) from the cavern below street level.

The cavern will eventually house a tunnel that will connect the former TBM launch box cavern (between 92nd and 95th streets) with the existing tunnel under Second Avenue that starts near 99th Street.

The existing tunnel between 99th and 105th streets, which is not currently in use, was constructed back in the 1970s.



12/8/12
97th Street, SW corner

A view down into an excavated area near 97th Street.

The four steel pipe struts in this image are waiting to be installed inside the tunnel cavern that is being excavated under Second Avenue between 95th and 99th streets. Each strut weighs about 40,000 pounds.



10/27/12

An earlier image of the same location. Note the large corner bracing beams that are in use at this location.



10/27/12

An image of a pressure gauge that I noticed on the side of a tank inside the construction area.



12/8/12
btw. 96th and 97th streets, SE corner - looking W

Workers on a Saturday use a crane to reposition material inside the cavern below.



10/27/12
btw. 96th and 97th streets

Oblivious to plans and progress in the construction zone, a squirrel buries an acorn.




10/27/12
btw. 95th and 96th

A view of the temporary roadway decking above the cavern. In the 1970s, the contractors working on the Second Avenue subway up in Harlem used wooden timbers for roadway decking above their tunnel caverns.



12/8/12
btw. 93rd and 94th street - looking S

The drill rig on the left is being used to excavate a section of secant walls at this location.



12/8/12

A closer look at the sections of secant walls under construction at this location. Note the steel beams that have been placed inside each of these secant wall sections.



10/27/12
94th Street, SW corner - looking W

This would appear to be a concrete pumping station. Concrete is trucked to this location and then pumped (from the red skips) into the work area below ground.

Correction:
According to a readers comment, the tanks in this image are being used to hold the spoils (excavated material) from the drilling of micropiles inside the old Rainbow Hardware store on this corner. This corner will become an entrance to the new 96th Street station.



10/27/12
93rd Street

A device that is being used for vector control, i.e. a rat trap.

87th Street, SE corner - looking SW

This image gives you an idea what is going on inside the muck house between 86th and 87th streets.

The blue skips are used hold the material that has been excavated from the cavern below until it can be trucked away.

The gray ductwork is part of the air scrubber system at this location.  The scrubber filters and cleans the exhaust air after blasting has taken place in the station cavern below ground.



10/27/12
btw. 85th and 86th Streets

Above, fall leaves gently cover the now quiet work site.



12/8/12
btw. 85th street - looking N

A set of holiday wreaths. The lighted digits "15" may represent Local 15 of the International Union of Operating Engineers.



12/8/12

A closeup of one of the wreaths.

The Christmas lights in the window are not a reflection -- they are actually hanging inside the structure.

1605 Second Avenue (btw. 83rd and 84th streets)

This sign, in the window of the "All Washed Up" laundromat on Second Avenue, announces that this location will soon be closing.



10/27/12
83rd Street, SW corner

This odd looking device is another one of the wet scrubbers that has been set up in support of the 86th Street station excavation project.

The machine is made by the company Schauenburg Flexadux Corporation. (Click on this link to see how this machine works.)



10/27/12

When I took these pictures, workers were in the process of building an enclosure around part of the machine.

Christmas wreaths on the doors of a local restaurant with signs of the ongoing construction on the left.



12/8/12
87th Street, SE corner

For the longest time a homeless man, Jose Perez, occupied this corner just north of the Food Emporium, together with his dog.

Sadly it has been reported the man has recently passed away.

A view from inside the west crossover cavern just south of 69th Street under Second Avenue.

The tunnel on the right leads to the north side of the upper level of the 63rd Street/Lexington Av station.

In Phase III of the project, the MTA will mine a new tunnel into this cavern from the south. This new tunnel, which will break through the wall in this cavern just to the left of the existing tunnel, will allow this line to continue south under Second Avenue.




The following report was recently posted on the MTA's web site:


Second Avenue Subway
MTACC Quarterly Progress Report to Capital Program Oversight Committee
December 2012

Here's a summary of the report:

The project is "on budget" and is on schedule to meet the December 2016 revenue service date.

But with that said, the MTA's Independent Engineering Consultant believes that there are only 45 days of scheduled contingency remaining - which is not much, considering that there are still four years of work to do.
