Tell me those three expresses, 1'18", 53", & 2' emit less sound than expresses in the past did, right? They're barely noisy

Is the depression of the tracks a new configuration of the express lines, do you know if this is why no express seems all that noisy?

At 33rd Street it's so that the express tracks can go underneath the Murray Hill road tunnel.

I think you might need to rephrase your question. I've read it over a few times, but I have no idea what you're asking. I know that you are a public transit expert, so I wonder what you mean by "new configuration" since I'm sure you are aware this is among the oldest stations in New York (1904).

Expert? far from it! I'm merely interested (passionate). My question's two-fold:
  • were the centre tracks sunk since inaguration (yes? no?)
  • must/do you suppose the sinking of those tracks mitigate/s their noise pollution (yes? no?)

(Yesterday evening, I was trying to recall whether the Murray Hill tunnel was the two-way 1930s highway underneath Park Ave, or the modern one-way two-laned bypassing expressway under Lexington? 2nd Ave? ... today, I'm guessing it be the former.)

The wikipedia article on the Murray Hill Tunnel (http://en.wikipedia.org/wiki/Park_Av...unnel_(roadway)) is helpful. There is no roadway tunnel under Lexington Avenue. There is one under First Avenue at United Nations (First Ave is called United Nations Plaza in that area). That tunnel, like the Murray Hill Tunnel under Park Avenue, is one-way only northbound, although the First Avenue Tunnel has multiple lanes.

Given that the Murray Hill Tunnel dates back to an open cut built 1834 (that was roofed over in 1850), it is safe to presume that the sunk configuration was present since the 33rd Street station was built. Why it was built like this, and why the local tracks and platforms were not built a little lower so as to be level with the express tracks, I don't know. The best way to mitigate noise pollution is to build local and express on totally different levels, as happens on some stretches of the Lexington Avenue Line through the Upper East Side.

It appears that different construction methods were used to build the express and local tunnels:

Quote:
The tracks north of the station: The express tracks in the station are significantly lower then the local, this is because just north of the station is one of the few locations on the original IRT that the cut and cover method was not used here. There is a deep bore tunnel under what was a trolley tunnel and what is now the vehicle tunnel under Grand Central. There are two tunnels one for the local and express tracks for each direction. The tunnels are obvious since there are no columns in them and there is a curved ceiling, just before the station local trains go up a steep incline into the station.

The entire Flushing Bound 7 Express trip in one video. Enjoy the trip and all the quirkiness that is the "International Express":

Bravo, I thoroughly enjoyed that, fascinating above-ground ride had me grinning from cheek to cheek ... I like your trainspotting too ... how come the express track's raised above the locals around 111 St?

Nice video.. I rode that Flushing line a many of time in the summers of '69 & '70 traveling to and fro from Shea stadium..

trainrover wants to know..
Quote:

according to wiki..

Quote:
111th Street is a local station on the IRT Flushing Line of the New York City Subway. It is served by the 7 train at all times.

At this point, the express track "flies" over the other four tracks. The two center tracks are yard leads of the Corona Yard, home of the 7 train. As a result, trains that go to/from the yard often terminate or begin at this station. Stations with flyover express tracks such as this were far more commons on IRT elevated stations in Manhattan of the 19th and early-20th Centuries.

This station has full windscreens except at the south end of the northbound platform, which has a waist-high steel fence instead. Exit is at the south end. The mezzanine and stairway landings are wooden while the flooring at the fare control area is concrete. The station has a crossunder between platforms. New signs have covered the old ones.
