Such would allow for more long-term operational flexibility and allow for such a Broadway-Brooklyn line to Canarsie to continue even after the (L) tunnel shut down ended while the (L) can better serve the much more heavily traveled portion of the line.Not quite. Only CBTC equipped trains can operate on any portion of the line between 8th Ave and Rockaway Pkwy. The detection of a single non-CBTC train on the tracks forces the auxiliary wayside system (AWS) into operation. This was designed to handle only 3 tph, enough for work train operation during the midnight hours and no more. It's a string of absolute blocks between switches. Operational flexibility on the Canarsie Line was eliminated when the line's original block system was removed as the last stage of CBTC implementation. |

As noted elsewhere, it was mentioned the signals are still in place on the Atlantic Avenue-Canarsie portion of the (L) so that non-CBTC trains can get to the yard at the end for washes from what was mentioned.That was why I said what I did. What they would likely have to do if necessary is re-install signals on the (L) between the flyover and Rockaway Parkway for this purpose, which they appear to now have two years to do. |

Running time between Bedford Ave and Union Sq is 6 minutes. Add a minute for changing direction and it comes to 7 minutes each way or 14 minutes round trip. That bumps it up to 4 tph.If this were an MTA press release, it would be hailed as a 33% increase in service. Of course, this assumes that operations could keep move that 2nd train from 8th Ave to Union Sq in time. It also assumes that the tower operator is sufficiently alert to throw the switch the instant the 8th Ave bound train clears it. |

Trains come in to 3 Av on the single track that is in use, possibly crossing over between there and USQ, then come in to USQ and discharge all passengers.It's 4000 feet from USQ to 8 Av. That holds 8 trains on each track west of USQ. These are trains without passengers so you can run red signals at a few mph to stack them in tightly. You can hold another 4 trains on the unused track between 3rd Ave and 1st Ave (the track whose tunnel is being worked on), and the final 2 trains within USQ station itself. That's 22 trains. The track between USQ and 3 Av is held clear for switching maneuvers. I'm sure it's unrealistic and cumbersome but it's not impossible. |

Then use CBTC-equipped trains for trains running to/from Rockaway Pkwy that go onto the Jamaica el at Broadway Junction. It must be possible to shut off the on-board CBTC equipment, otherwise we wouldn't have R143s running in revenue service on the J now. There will be spare R143s available when the tubes are shut down. How difficult could it possibly be to shut off/turn on the CBTC equipment on trains switching between the Jamaica and Canarsie lines between Broadway Junction and Atlantic? |

The average walking speed is 4.54 fps (105s for 8 cars, 132s for 10 cars). So it would take definitely require two operators. That said a 15 minute interval in Manhattan would lead to major crowding until riders realize the L isn't an option. Better to force them to other routes beforehand. |

How would the last 18 trains platform at 8th Ave? Will we couple up and make the passengers walk? That seems unworkable even if you can turn quickly enough and get them out of the way you can't unbalance the service since all of the trainsets will be on one side of River. Then of course there will be a BIE. |

Maybe with an operator at each end...Let's differentiate between physical and management constraints. The Flushing Line used to turn 36 tph at Times Sq. The physical constraint was brake recharge time. They had an operator waiting to enter the train while the trains were entering. The management constraint would be waiting for that operator to walk the length of the train before recharging the brakes. A large number of people will be inconvenienced regardless what plan is implemented. The public will be very angry, if a substantial part of the inconvenience is due to management or work rule constraints. |

Perhaps my explanation wasn't clear.CBTC-equipped trains can run anywhere without affecting other trains on any line. Non-CBTC trains can run anywhere. However, if non-CBTC trains are anywhere on the Canarsie Line, the signal system will revert to the AWS mode. This mode can handle only 3 tph. There will be spare R143s available when the tubes are shut down. How many? The following is left as an exercise for the reader. There are 212 R143's and 32 R160's that are CBTC equipped. 24 trainsets, comprising 192 cars are required for peak am operation. The rest are spares, some of which might be undergoing maintenance. The running time from Canarsie to 8th Ave is 38:30. The running time from Canarsie to Bway-Jct is 10:00. The running time from Bway-Jct to Myrtle-Wyckoff is 6:30. The running time from Myrtle-Wyckoff to Bedford is 13:00. |

The whole idea of sending 20 trains into Manhattan and then 20 back out on a single track has far greater problems with the laws of physics than minor details about how to store trains up close against each other. :)I suspect the crowd control problems on the Brooklyn side would be totally unmanegable. Besides, you can get almost as many tph if you bring 10 in and then 10 back out as if you do 20. |

That's 244 cars in total, although I believe four cars out of the 212 R143s are permanently out of service due to a crash in Canarsie Yard that caused significant damage to one of them. So it's really 240 cars. Even so, 192 is what they need for the present, full-length L service. They won't need that many when the tubes shut down. If they shut down just one tube at a time, they'll have to run significantly reduced service in both directions due to single-track operation between Bedford and 3rd. If they shut both down at the same time, they would be unable to operate L service in Manhattan because they would have no way of getting trains in and out of the 14th St section with no track connection to any other line in Manhattan. Either way, subway cars will be freed up. |

Wally - your words:I'm assuming both tubes will be shut down during this. Until we hear otherwise, that is the assumption I'm working under.

Right now there are 12 tph to downtown and 9 tph to midtown over the WB. The overwhelming majority of riders diverted to the L will be wanting midtown. So at least 2/3 of any added trains should go up 6 Av. The 6 Av route has connections to the 6, 1/2/3, N/Q/R, and 7. |

As one "removes" L-trains for some other purpose, for example "proposed Canarsie Trains via the J Line", the remaining trains have to pick up the slack especially at the western Brooklyn stations with their increased ridership! This would easily create longer wait times for the crowded remaining L-trains that have to attempt to get these riders to the transfer stations. Just how much backward or forward riding just to make a transfer large numbers of riders will have to do is an unknown? In any case it will still be large numbers of folks traveling about for transfers.Shuttle buses at every station may reduce some of the ridership on the platforms. Just how much of the subway ridership switches to shuttle bus usage for the first part of their journey is an "un-known". In the past the slow moving shuttle buses has meant longer travel times and involve the need to transfer to a subway further down the road. Some folks have not forgotten that very awful entire period of frequent L-train shut-downs due to the installation of CBTC - where major portions of the L-train was repeatedly bus substituted and shuttled? The lines, non-frequent trains, wait times, transfers to buses were horrendous. The 14th Street Tunnel closure will involve the rush hours, unlike the CBTC installation. Then shut-downs occured weekend upon weekend often with mid-day and over night shut-downs to content with - for weeks on end! Now some folks act as if, "shuttle buses" are some whiz-bang solution. The walking transfers to between the G-train and the J-M-Z trains may help some riders, but how many is an open question. One would still have to take the remaining less frequent over-crowded L-trains to the G-train, wait for the G-train, then take the G-train to the station for a walking transfer, and re-enter the subway for the J-M-Z train! Increasing the wait times for over-crowded L-trains riders helps how? How does reducing service of the L-trains at the higher ridership western stations help those riders? Can L-train riders transfer to A, C, J and Z trains at the Broadway Junction station? Of course they can, they have been doing that for decades, and will continue to do so. Millions have used those stairs and escalators millions of times - it is not a big deal. Of course that transfer station is very important and helpful with any closure of the 14th Street Tunnels. Will the creation of a "proposed Canarsie Trains via the J Line" route help L-line riders at the higher ridership western Brooklyn stations? So far the answer is not looking like a slam-dunk positive! Of course, create shuttle buses and enhance service on existing buses, create a limited bus direct to/from Bedford Avenue & Manhattan, and strongly push riders to transfer to the A, C, E, 7, G, J, M, Z lines - with as much information and community involvement as possible. All of that is appropriate! All of the above will real understandable schedules and estimates of the travel times involved for each method. Large numbers of people will be inconvenienced regardless what plan is implemented, in my view - creating proposals that increase wait times and crowded-ness on the remaining L-trains is not a solution. The public will be very angry, as their travel times, and "around - aboutness increases" to very high levels. Does anyone really think that current N-train riders are "happy" or "thrilled" with their all hours round-about trips on the Sea Beach line? Think again! Mike |

My plan has ALL added trains going up 6th avenue during such a shutdown, most likely with the (M) at peak times doing 8-9 TPH to 71st-Continental and my "Orange (T)" doing 6-7 TPH at all times (19/7 with late nights 3 TPH) to 96th Street and 2nd AvenueDoing it this way likely reduces the number of trainsets needed (even if by only 1-2) and has the added benefit of giving UES riders direct 6th Avenue Service (as well as Broadway-Brooklyn riders direct midtown service 24/7). |

Which is EXACTLY why I would do it, actually to six tracks because the Snediker Avenue platform could then be used as a terminal for a short-turn (L) most of the time or for storage and the others can be used as through and/or terminal tracks depending on which services would go where. |

Increased wait times west of Myrtle-Wyckoff may end up being a factor anyway, depending on how MTA decides to do the shut down. |

A train every 5 minutes is better than other lines can do at any time, let alone during a severe disruption. Since the segment between Myrtle and Lorimer is the most isolated short turns at Myrtle can boost service there if it isn't enough, but I doubt that. The question is can the G train cope with all the people being dropped off at Lorimer, the answer is of course, no. The G would have to go to 8 cars at least during rush hour. |

Naturally the G will boost service and consists when the L work commences, especially if it's done in rush hour. The problem is the transfer stairway is at the extreme north end of the G platform. A challenge is going to be for passengers to spread out the entire 600' or 480' on the platform, according to the length of G train. |

Depends how wide the platform is. Northbound 4/5/6 at Union Square is heavily used, 45 trains come in per hour, not a hugely wide platform, and all stairways are in the front half of the platform.Nevertheless, passengers do make their way all the way to the back, and plenty of people load the last few cars. |

This is why I would truncate the (L) to Broadway Junction during this time (there are switches coming out of the portal that allow this) and run a direct service to Manhattan via Broadway-Brooklyn (whether that is my re-routed (C) or the other suggested one labeled (K)) from Canarsie. Doing that would allow the (L) to concentrate on the much busier and more isolated portion of the line. |

Which is also why I would during this period add three new OOS transfers between the (G) and (C) at Lafayette Avenue, the Broadway-Brooklyn line where those cross with the (G), and between the (G) and 2/3/4/5/B/D/N/Q/R and by then possibly (W) at Atlantic-Barclays. The idea would be to encourage passengers who must do the (L) to the (G) to whenever possible take the (G) the other way to the Atlantic Complex and use that to get to Manhattan even if it takes longer. |

It would require 3 crews to keep this one train going back and forth, minimum. So it's not efficient in terms of moving passengers, or manpower. Not really good for the equipment either.The public will be very angry about this whole L train situation, period. Whatever the MTA decides to do. I don't know that negotiations between labor and management are going to become public knowledge, or tip the scales much. Hell, all I was thinking at first about the one-minute turns is, when are those poor guys going to pee? |

Hmm...when the new service began,it seemed as if there was Way more service heading to midtown than lower Manhattan.Perhaps a slight increase is in order for uptown trains(3 tph peak periods)...since its pretty obvious that midtown is a more desirable/needed destination.. Its also pretty obvious that the uptown routing should be a 24 hour service. |

Hmm...when the new service began,it seemed as if there was Way more service heading to midtown than lower Manhattan.The schedule says 8 rush hour Ms and 12 J/Zs. I take the 6 Av line sometimes and the 8 Ms seems about right. Don't know how many J/Zs there really are. |

No. What I mean by another service, I mean a completely different branch line, like the Fulton el, not a shortened version of an existing line. If they do rebuild it for the reasons you specify, it will likely NOT be a restoration of the Atlantic Ave station we all remember, but instead an elevated train yard like at Van Cortlandt. After all, why waste space keeping old platforms (esp. the Snediker Ave portion) when they can put in extra storage tracks? |
