  1. Walk to Carle Place. Transfer at Jamaica to E then M/R.
  2. Perhaps during a mid life R188 style overhaul, reconfig to 5 car. A-A pairs are always a choice.
  3. 600/10 vs 480/8 stopping mistakes are why R46s were removed from the C.
  4. R46s tend to have same problem when in stations with door open. Door gravity slides closed 1.5 inches then door motor reyanks it open, it drifts closed, motor yanks it open again, until door officially closed and light off. Hearing it dift on a rolling SMEE is new to me.
  5. Afaik they r used for auto annoucement triggers atm 2 avoid odometer drama since r160s came out day 1 2009 or whenever. True?
  6. TBM a 4th track under the existing 3, 145 and fordham is already have room for 4. I cant remem if the D's bridges over cross streets on Concourse have room for a 4th track or not.
  7. Because of where the suspension is, if roof is narrower you can have a looser suspension because the train rocking more wont hit the tunnel walls/conduit/structure gauge.
  8. I took a look at the Piper UWB equipment on 7 line. Few or none of the nodes have a backhaul. Just 120v. They are radio data packet repeaters, not Access Points with their own fiber optic backhaul. I also suspect the next train UWB itself is a rolling radio repeater mesh node. So even though it is NOT AV, if there is a poor to low signal, a train will talk to another train that talks to a repeater node that talks to a backhauled node to a zone controller for CBTC packets. On QBL there are radio nodes ever 600-1000 feet. Almost as bad automatic block track circuits in sheer equipment count, And each legacy radio node must backhaul. Piper equipment just requires 120v, and almost no backhaul cables since it is a mesh network, not a hub spoke wifi system.
  9. Power shutoff for GOs always has seemed more precise than 12-9 power shut offs IME. I'll ask, when it is a GO do workers open knife switches or manual switchgear in a closet somewhere? But a 12-9 requires immediate REMOTE power shutoff that uses motorized switch gear controlled by "telephone lines" from RCC and there are far fewer of those, and they shut off the whole substation, not any particular track or 3rd rail "circuit"? Or does FDNY/NYPD have far stricter rules for power shutoff than MOW, all tracks, 2 miles or 2 stations in each direction from incident location?
  10. So in that youtube video with UWB radios, did I see a forward in-cab camera? FRA style. Kind of interesting NYCT would adopt forward cameras for post suicide litigation. What is NYS law anyways for NYCT liability payout to family if someone gets killed under the train? All suicides get payout or only if you are pushed under the train (murder)?
  11. Transpocamp and transitcenter advocacy events are closest to a transit social event. They are public transit events not foamer events. There is a difference. I always find both enjoyable. NYTM events years ago used to be very "social" but i find them very kid orientanted or transit irrelavent since Cuomo took over and told NYTM to stop being political.
  12. Next gen probably chargers Dual mode Locos will be primary electric in third rail territory instead of primary diesel as with the P32s.
  13. CBTC AWS installation. All 1930s signals must be replaced for CBTC's AWS backup block signals. Whatever signals arent upgraded will have their blocks combined & heads & trips removed.
  14. How low did PM shoulder E/F frequency have to be for G to not delay E/F by relaying infront of both express tracks?
  15. Why was implementation of Fulton Express one of last set of express tracks ever put in service? Bed stuy/ENY depopulation shortly after the IND opened caused the 4 track IND Fulton to have been a "mistake"? Sea Beach, Jerome and Astoria are still have unused express tracks. And Jamaica's express tracks were never installed.
  16. Is MTA a civilian employer or law enforcment? Does an Inspector General have subpeona/discovery/law enforcement power? HIPPA is nearly wothless as everyone waves all their rights when they sign up for insurance. All HIPPA does is stop glossy viagra ads & smoking settlement lawsuit flyers in the mail.
  17. Lexington Av-63 St platforms are underneath the 4/5 59 street tunnel with the 4/5 tunnel underpinned inside 63/Lex. You can hear IRT Exp roll through on the upper level of 63/lex. It would be very simple to just mine/blast a 3 block hallway along the 4/5 tunnel until it exits onto the 59/lex IRT Exp platform. A moving sidewalk, some NYCT is allergic to would make it 1 station on a map.
  18. But the proposal of Flushing Line converted to Div B with Main Street being destination of either N/W/Q, and leaving Queensboro Plaza to 34 Hudson Yards with Steinway Tubes as Div A, means the IRT Flushing line stub will deadhead to corona yard over Div B tracks.
  19. 1968 Plan For Action which involved converting northern half of Pelham line to Div B, Whitlock Avenue going north, to go down NEC to Oak Point yard to SAS, but the 6 train stub that ended at Hunts Point Avenue would deadhead with Div A stock to Westchester Yard every day down the now Div B Pelham express El track.
  20. WillyB was built with SIX tracks. Right now it has two tracks. https://cdn.newsday.com/polopoly_fs/1.10694988.1439322907!/httpImage/image.JPG_gen/derivatives/display_960/image.JPG I've heard of a napkin proposal to rebuild from Marcy to Myrtle to be 4 tracks. J train skips Marcy and Flushing Ave after Myrtle making the J faster for eastern riders. Deinterlining M and J except for going over the bridge (balloon loop). Lorimer and Hewes are closed/combined/rebuilt into a Union Ave, ADA, transfer to G, 2 island new express stop. Flushing Ave has an express track built over the current express track. Myrtle either has a separate M platforms or Islands. Possibly stacked islands (think Queensboro Plaza). Essex Street is rebuilt to 4 tracks so M and J never have a conflict for a platform. There already is a little bit of balloon loop operations already at Essex Street with how M will wait doors open at Essex taking on additional customers while a J passes infront onto WillyB. MacArthur, 12 street ,19 street BART has something similar. https://commons.wikimedia.org/wiki/File:Rail_Tracks_map_pattern_24A.svg An example of balloon looping or simultaneous loading, but most metros that do that only do it for the merge (3 tracks) not for split direction for cost reasons. Since train separation distance is 10-15 seconds, platform dwell time becomes highest capacity limit, not ATP. ^^^^ track layout allows huge dwell times without affecting TPH.
  21. Bus 163 is a mirror of Pascack Valley line which has 1 track and 2 hour headways, and Teterboro station was intentionally walled off from its residential neighborhood to make sure it was a programmed death. NJT long also decided to abandon diesel rail and replace it with Cruisers that pickup in the heart of residential areas, which rail lines which are surrounded by commercial uses, cant.
  22. 7 line is Thales CBTC wont be used ever again AFAIK by NYCT. L train's Siemens equipment supposedly will be used for rest of Div B and A so what a mainline IRT CBTC R142A is parts wise, is yet unknown. Thrown in LCD ad screens too. If the MTA is very adventurous (not), CCTV too.
  23. The local tunnel/track was shifted outwards at 72 street West IRT to put in elevators on widened platforms. Pretty damn impressive for 21st century extreme costs and penny pinching by MTA.
  24. Things of bankruptcy that can be done. Changing labor contracts, specifically things like maturity/liquidity (balloon payment as lum sum of pension if condition X is met) which affects how long into future pension assets can be locked up can be done in bankruptcy. Layoffs/seniority/payscale can be changed in bankruptcy. Early terminate managerial staff yearly contracts. Rebid maintenance contracts (assuming no vendor lockin hahahaha) before they expire naturally. Terminate a material supply contract that supplies obsolete parts that will be dumpstered on arrival. Defaulting on property leases. Void a vehicle mortgage without paying remaining interested or principal as a penalty for default/repo (probably limited to 4 wheel off the shelf MTA non truck non bus vehicles). Typical recipe of bankruptcy is if bonds are tiers/category/priority, lowest tranche is defaulted or interest cancelled.
