Old NY City Hall Subway Station

Posted on November 17, 2013 by geek

Saturday, I got to tour the abandoned New York City Hall subway station. The New York Transit Museum gives tours of it a few times a year, and this tour is completely worth the membership in the museum. The old City Hall subway station was originally the southern terminal of the original Interborough Rapid Transit (IRT) subway route. The station is located on a single 600-foot long track loop that is located south of the current City Hall/Brooklyn Bridge subway station. The track loop is still used by the #6 subway line. After a #6 train drops off passengers at the City Hall/Brooklyn Bridge station from a southbound route, it then uses the loop to return to that station as a northbound train. For our tour, we met at the southern end of the City Hall/Brooklyn Bridge subway station, and then once all passengers had been offloaded from a southbound #6 train, we got on for the short trip to the old City Hall station.

The old City Hall station has a platform that is 400-feet long and is completely curved. This short and completely curved platform is part of the reason why the station is no longer used. The ten-car trains now used don’t fit in the station, and it is a serious hazard stepping off the train to that platform. [Our MTA guides used a short wooden platform to allow us to easily and safely get off the train onto the platform.] The station was closed in 1945 because passengers preferred the Brooklyn Bridge station due to its longer and straight platform and also because both local and express trains stopped there.

The station is completely gorgeous. There is a mezzanine level where passengers would buy tickets. The mezzanine is square with four arches that form each of the walls, and an arched ceiling joins the four arched walls. At the center of the mezzanine ceiling is a glass skylight. One of the arches of the mezzanine forms a passageway that leads down to the platform. The platform is then made of 15 more arches. Three of the arches have three glass skylights each. Electric chandeliers hang from each of the arches to provide light. All of the arches are created by Guastavino tile arches. The walls and ceilings are covered in green, brown, and cream tile. Interestingly, much of the cream tile is unglazed and rigged. Evidently this tile was never supposed to be exposed, it was rigged and unglazed because it was supposed to be covered with cement, and the ridges would provide more surface are for the cement to stick, in the same way as when tiling, the ridged side of a trowel is used to create ridges in the cement before placing the tile. However once the tile was placed, the station architects liked how the exposed ridged tile looked.

One thing I have always appreciated about the New York subway system is the tile work. All the stations have tile work, and generally each station has a somewhat unique tile work for at least the station signs. Some stations have really unique and beautiful tile work for example the Times Square and American Museum of Natural History stations. The tiles themselves in the old City Hall station are not gorgeous, but the way they are placed together in the arches are. Therefore for final comparison, below are the station signs at the old City Hall station and the new City Hall/Brooklyn Bridge station.

Delancey Williamsburg Bridge Rail Terminal

Posted on November 14, 2013 by geek

I joined the New York Transit Museum this year so that I could go on some of their members only tours of some real cool transit places. Today I toured one of those places, the old Essex/Delancey trolley terminal from the Williamsburg Bridge. Trolleys from Brooklyn came across the Williamsburg Bridge to Manhattan and then turned around in this terminal. Trolleys in Brooklyn were evidently on a different rail system type and thus couldn’t continue onto the Manhattan rails. I won’t try to give the history, as so many places can be found, which do it much better, such as this one. The terminal is right next to the Delancey and Essex subway stations and can be seen from part of the platform. Inside the terminal area, some of the old tracks, paver stones, and rails can be seen. While I found those interesting, I also just loved being able to walk in a behind-the-scenes area that the general public usually can’t access.

Another thing I found interesting was the condition of the columns and beams. Like almost all parts of the New York underground, the area is continual being eroded by water that seeps in from groundwater and storm water that flows through various cracks in the utility areas. Thus much of the metal support structures were badly rusted. Some parts of the area have been rehabbed but not all. It was a stark reminder of how continual maintenance is needed on essentially everything humans build. If you are not an engineer, you can be forgiven for not understanding that once something is built, it still needs maintenance. It can’t just simply be left to itself to continually function properly for all eternity. Unfortunately most politicians, who hold the purse strings to maintenance funding, don’t seem to understand this.

There is an idea or plan by some to turn the area into an underground park called the Lowline. It would be incredibly interesting to see that if it happens. In the meantime, I’m glad I got a look at this piece of New York’s transportation history.

Book Review: “Conquering Gotham”

Posted on October 10, 2013 by geek

This isn’t really a proper book review but really more of a book recommendation. I’m not a writer or literary critic. I’m just an engineer who just finished reading a book about the history of one the greatest engineering feats in the early twentieth century and want others to know how interesting a book it is. The book is “Conquering Gotham: A gilded age epic: The construction of Penn Station and its tunnels” by Jill Jonnes (Penguin Group, 2007).

The book chronicles some of the history of various people and companies who tried to link Manhattan Island and New Jersey via bridge or tunnel. When the book starts, the Brooklyn Bridge, which was an engineering feat in itself, has been built, but the only railroad connection to Manhattan Island was via New York Central and its bridge over the Harlem River. Thousands of commuters, other people, and cargo must use ferries across the Hudson River everyday to get to Manhattan from New Jersey. Dewitt Clinton Haskin unsuccessfully attempts to build a tunnel underneath the Hudson River, but due to construction and financial problems, the tunnel was abandoned. [Decades later the tunnel would be completed and in present day is used for PATH trains.] Gustav Lindenthal unsuccessfully tried for decades to build a bridge across the Hudson River but was never successful due to an inability to get funding. Pennsylvania Railroad (PRR) under the leadership Alexander Cassatt is determined to get their trains into Manhattan in some manner instead of having their tracks end in New Jersey and their passengers needing to take ferries across the river.

The book describes how PRR explores the possible ways to get their trains to Manhattan Island and finally settles on an audacious plan to build two tunnels underneath the Hudson River, two tunnels under and through Manhattan, a grand station in a not so nice section of Manhattan, and four tunnels underneath the East River to further expand their tracks into New England. Completing this audacious plan is fraught with many engineering and financial difficulties and is further complicated by the need to deal with the corrupt New York City Tammany Hall politicians, which put about as many delays on the project as the difficult engineering. The history is fascinating, and Jonnes describes it really well. The book is not a dry history textbook. She describes the engineering obstacles in a way in which a non-technical person will understand and be interested, although as an engineer, I actually would have liked more details about some of the engineering issues, particularly with the tunnels.

The final chapter describes some of the post-completion problems, including the eventual decline of the railroads due to automobiles and then aviation. The modifications made to Penn Station after its completion and finally its destruction and replacement with the atrocious Madison Square Garden are also discussed. I have traveled on Amtrak trains many times via the Hudson River tunnels and twice via the East River tunnels. I have a much better appreciation for the difficulties in their construction now. I am also now even more sad to have never seen Penn Station in its original glory. In my humble opinion, the current Penn Station with Madison Square Garden is the ugliest and most ill-designed train station ever, and New York City deserves so much better. Of course, New York City is partially to blame for the destruction of the original and the construction of the current Penn Station.

If you are at all interested in history, transportation, or engineering, I highly encourage you to read this book. It is a great read. [I received no compensation for this recommendation, and I checked this book out from my local library.]

Central Park in June

I love New York City’s Central Park. Then again, I suppose anyone who has ever been there loves it. I spent part of my recent trip to New York wandering around Central Park. Here are a few photos from my visit.

New York’s Highline Park in Bloom

Posted on May 31, 2013 by geek

Last January I visited New York’s Highline Park for the first time. I thought the park was wonderful even in winter when all the plants are dormant. On my next trip to New York, I had to go back. The park is even more beautiful in summer when all the plants are green and flowers are blooming. It is a wonderful oasis above the busy Manhattan streets. Below are a few photos from my most recent trip.

New York’s High Line Park

Posted on January 6, 2013 by geek

New York is a city so dense that they actually created a park elevated above the street. The High Line is a park created on an abandon, historic freight rail line that is elevated above the streets of Manhattan’s west side. The elevated structure was threatened with demolition, but community residents formed the Friends of the High Line and successfully fought for its preservation and transformation into the lovely park it is today. The first part opened in 2009, and a second portion opened in 2011. They are currently working on transforming a third and final section. The entire length of the structure has a paved trail, and there are plants almost the entire length of the trail. There is also public art along the park. The designers did a nice job of preserving the structure and accentuating that the park is built on an historic rail line.

In many places the rail tracks were left in place, and plants were planted in and around them.

It has a lawn area.

It goes under buildings that straddle the old tracks. There is an amphitheater of sorts that allows you to view the street below.

There are seating areas all along the park. This area has some nice lounging chairs.

The lounging chairs are really cool. Some of them are on wheels that roll on the railroad track, although they were locked, so they can’t be moved by the general public.
