The Canarsie Tunnel consists of 2 tracks (Q1/Q2) of the “L” subway line between First Ave Station in Manhattan and Bedford Ave Station in Brooklyn.

5. Replacement of damaged signal cables and equipment; and replacement of tunnel lighting cables and fixtures.



The key elements of work are described as follows:

Demolition of upper wall ducts (inner wall) between Avenue D shaft in Manhattan and North 7th Shaft in Brooklyn for a total of 6,872 feet.

2. Power System: Removal and replacement of various power cables throughout the tunnel, including negative feeder cables, positive cables, battery cables, control cables, and Tunnel shell protection cables.

3. Communication Systems: Removal and replacement of various communications cables throughout the Tunnel such as 36-strand Fiber Optic Cables (about 50,000 LF), various sizes of Copper Cables (about total: 41,350 LF) and Radio/Antenna Cables (15/8” Radiating Cable and 7/8” Non-Radiating Cable – 38,000 LF) on the walls and/or in the duct banks of the Tunnel. Work also includes removal and installation of 40 Emergency Alarm/ Emergency Telephone units to be provided by NYCT and removal and replacement of FDNY sound powered telephone cables and jacks.

4. Circuit Breaker House (CBH) #61 and #62: Removal of existing Circuit Breaker House #61, currently located mid-river in the Canarsie Tunnel, and construction of new CBH #61 at the location adjacent to Emergency Exit 171 below East 14th Street near Ave B in Manhattan. Removal of existing CBH#62 and construction of new CBH#62 at the location adjacent to north end platform of Bedford Avenue Station. For these two CBHS, remove and install positive, battery and control cables; copper buses; control terminal box, RAIC; relay panels, battery switch box, lighting fixtures, heaters, switches and cables; install flood doors.

5. Track: Replace about 5,000 LF of rails between Avenue D and North 7th Vent Shaft (2500 LF on each Track Q1 and Q2. 6.

They should definitely extend the M past Essex when that happens.

And it's appropriate, just as it was when the 7-line users, hardly hipsters, wailed about weekend service cuts.

They usually extend the M to 57th/6th when the L goes down.

Yeah. They turn M trains there on weekends when the L is down, they turn Q trains there at night when the BMT is closed for Fast Track and they turned B and Q trains there in 1998 when the line between there and Lexington Avenue was closed for some reason.

...and they turned B, F, KK, JFK, and various other trains there when it was a terminal station prior to 1989.

I would this time myself extend the (M) and have it go to 145th/St. Nicholas (via the (B) after 47th-50th) since the MTA to use that as an experiment to see if on a more permanent basis having a 6th Avenue-CPW local is worth it.

For that, they may as well run the B on the weekend.

Yes, but it is a very QUICK turn so they do not block F train service.

For this type of a shutdown, I would seriously consider having the (M) go to 145th Street-8th Avenue OR (once the SAS opens) 96th/2nd on weekends UNLESS the (M) can run its regular weekday route on weekends while Queens Boulevard work goes on.

57th/6th is not ideal for a long-term terminal (even on weekends) due to the (F) using that as a through station.

And it's only been done occasionally. If the MTA is ok with turning M trains at 57/6 every weekend while the Canarsie tubes are being repaired, then that's probably the best option.

There was a time when the NYCTA limited the number and location of GOs that could be operated at any one time, but unfortunately that is no longer the case so it’s hard to predict what would be the most appropriate routing for a long term extension of the M when the N 7 St tube goes out.

While an occasional short turn operating may be acceptable, a semi long term operation as would happen when the N 7 St tubes are out would not be.
