  1. I cant tell from TTC's PDFs and contracts if TTC's/Thales "SCS" is PRR <200 Hz metronome pulse code (#1 purpose anti-collision, PSR secondary purpose) or no electricity, no relays, no track circuits, magnetic indusi transponders (no anti-collision function, only PSR). PDFs hint its unenergized baise with a wheel counter, maybe GPS, and PSR DB in a VOBC (ACSES over dark territory without ATC/ATP/cab signals). No radio link, no track loop link. TTC states "SCS" has "blue light" MOW function in its contract spec, but still, that would be an un-energized Balise clamped in the track bed temporarily by MOW in the simplest implementation.
  2. Extend every other or to bay ridge 95 and be done with it. Other choice is rerate all MOW trains to 30 mph or 40 mph from 20 mph so they can travel from CI to Concourse without slowing down service. Why are MOW trains stored 10 miles from their GO sites anyways? Something is wrong when it takes longer for a MOW train to go from its Yard to its GO site every night, than PABT to Philly by Highway.
  3. https://stevemunro.ca/2015/03/30/the-evolution-of-ttc-signaling-contracts/ Reading this article, and knowing TTC and NYCT share the exact same fixed block system and operating rules. The "SCS" overlay for TTC, NYCT never tried it, why? SCS would eliminate all grade timers with an "alerter". It sounds to me like TTC installed https://en.wikipedia.org/wiki/Punktförmige_Zugbeeinflussung for permanent speed restrictions/psuedo-cab signals but the transponders have no anti-collision function, only overspeed derailment or preventing suicidal notch 8 a train after an ST clears or notch 8 into bumper blocks after last GT clears.
  4. If there are questions about are R142As CBTC-ready? Answer is no. R142A has 1 operator screen, R188s have 2 screens. Consoles were completely replaced on R188s. But what I'm wondering, will Lex have the same Thales Seltrac as Flushing, or Thales equipment is blacklisted after Flushing Line and all future CBTC installs are Siemens? Did Mitsubishi ever create 3rd party CBTC equipment under the "I2S" contract?
  5. I have it on good authority that CAF was awarded the contract to refurbish the R38 fleet which is currently stored off the coast of NJ.
  6. QBL CBTC has only 1 work train and 1 work site per weekend. That work train has only 3, max 4 employees from Five Star on it. Easy to say all 11 miles of QBL is being resignaled by 1 person. That is why it will take years. Some weekends the CBTC train is parked all weekend at 71 ave and I never saw it leave. Five star never showed up.
  7. Auxiliary Wayside (legacy block with very long blocks) is primary signalling system, CBTC simply turns off block signals (green->flashing green) if a CBTC aware train tries to enter an empty legacy block, thus converting it to a CBTC block, or a CBTC aware train tries to enter a CBTC block (red->flashing green). A legacy train would get red until the last CBTC train leaves the next block, and then a legacy train may enter the block. The legacy block track circuits also need exercise sometimes. If its outside of peak, and the last CBTC train claims to have left the block, the block better not be occupied, if it is, it is a track circuit failure, but I wonder what NYCT's specs say happens if an AWS track circuit fails, CBTC trains run full speed through the block? legacy key by procedure/Form D, 1 train in the block? lock the trip cock down and stop on sight?
  8. What are the modifications? A B car is a B car right?
  9. Urine corrodes a mating surface. Daily News article reporting a wave of bum turds left on linoleum because of OGs. Car Inspectors file a grievance that the cars are unsafe to de/couple. Extreme tunnel noise. Very small MTBF when assigned to R train. Knee jerk reaction to someone in a wheelchair being injured at City Hall or 5th ave riding in the coupler. Todler amputates fingers on OG car, mom sues. Knee jerk reaction. Skel nods out flat on floor in OG for whole trip from 207 to FR, gets injured. Operations throws a tantrum that an OG set cant have isolated cars. Vetos any attempts to order them again. Bum smells up whole set is too basic of a reason. I tried to come up with less obvious ones.
  10. R179 clearance tests were done in 2016. R179 already visited all Div B trackage. I saw the R179s on 63rd street line and at 179th in 2016. These tests must be announcement testing as someone said or CBTC on culver or reliability testing of some sort. J has no high speed sections. All local, all timered. Even crossing the east river is slow on Willy B.
  11. Eastbound Exp to Lcl switch at 75th avenue is the largest cause PM E/F delays. Its BRAND NEW as of 2017 timer clears at 3-5 mph. Most T/Os just stop and wait. CBTC won't fix 5 mph timers on mainline, that was a policy decision. Timers on CBTC are FAR WORSE than block timers, since a CBTC timer won't clear till the front axle leaves the "zone", while when block GTs clear, the T/O can notch 3 it. The L train is a a mixed result. There are no timers on death curves in ATO. But L has very low TPH that never pushes the capacity of CBTC system. On 7's CBTC, which is still ATPM mode, not ATO. CBTC allow for "ST 5" ANYWHERE. 5-6PM West bound looks like LIE of R188s. I counted every train door close to door close, is 1:40-1:50 or 2:10 to 2:25. Sometimes 2-3 1:40 headways pull in right after another. CBTC lets trains pull upto 100 feet/2 car lengths from coupler of next train, anywhere on the 7 elevated. There is a capacity restriction policy by the MTA, that no train can pull into a station at all unless it has the whole platform vacated by next train, unlike LIRR/MNRR. So 7 trains will often be waiting 1-2 train cars apart, right before the station platform starts, even if the next train is 50% pulled out, the previous 7 will not move until next train is 75% or 100% gone from the platform. CBTC's movement authorities are calculated 100 feet at a time I think. So really quickly 200 or 300 feet to "red" can accumulate as next train pulls out, but rear T/O wont move till he has whole platform empty. Its a policy to never have a half pulled in train at a platform, but it kills capacity.
  12. Will never happen. Crew requirements/pick. No LEO for tresspass arrest at 71 avenue for fast fumigation.
  13. WB lcl and the express has been cut over to new signals from woodside to 33. CBTC in ATPM mode during rush hour with flashing green. EB local is still legacy signals. CBTC ends at https://www.google.com/maps/place/40°44'50.9"N+73°56'09.0"W/@40.7474732,-73.9363819,186m/data=!3m2!1e3!4b1!4m14!1m7!3m6!1s0x89c25ed539cdd9b9:0x5171b310b50fa0b6!2s32+Queens+Blvd,+Long+Island+City,+NY+11101!3b1!8m2!3d40.7468898!4d-73.9352119!3m5!1s0x0:0x0!7e2!8m2!3d40.7474811!4d-73.9358394 with very rough transition from CBTC to block signals at the 2 homeballs. "stop and sit for 5 seconds" problem at the 2 homeballs. ATPM seems slower than block since the WB timer between 52 and 46, with block, the TO usually accelerated into 46 after the timer clears. With CBTC the "timer" lasts all the way to the end of the 46th street platform and "lifts" at 1 car length before 11 car plate.
  14. LIght rail if it is its not a tourist attraction in the CBD is only built in america in 2 situations. Legacy railroad dedicated ROW or steal a lane (no sharing, not even for left turns, LE & EMS are only vehicles allowed to drive down the LRV lane) from a 45 mph vehicle speeds and 1/8 to 1/4 mile between lights arterial road. 2nd reason. Light rail was built for BUDGET reasons. Before LR the TA had one artic bus every 20 or 30 minutes on a route and it was standing room only, but the TA or politics say no new driverhires. An LRV is 2 or 3 artic buses. After building the LRV system, it remains at 20 minute headways. UTA Trax is my example. I almost want to say it is commuter rail but with street running to the CBD from the edge of downtown.
  15. Grapevine told me 33 to 61 is getting new signal heads/relays, CBTC wont be active in that section until there is a cutover to new block signals. Queensboro plaza was done mid 2000s. Main Street early 2000s. Tube early 2010s. "aslong as the signals are bagged, there wont be CBTC there".
  16. So with ATPM are trip cocks are always down but light aspects and block timers work just as before? I assume electronic penalty brake if a signal is violated, not a dump?
  17. CBTC was off friday evening rush hour. Eastbound to Main Street, screen said "Bypass" when I got on, at 74th a blinking "CBTC available" message came on and stayed on in addition to "Bypass" till Main Street. Its still not being used during Rush Hour.
  18. So "CBTC Equipment Supplier Interoperability" contract was an utter failure and this contract mod seals the deal that Div B is owned by Siemens for next 50 years?
  19. Thats what I wonder. Are all NTT B cars identical or car 2 of 4 must always be in position 2, ABA sets cant be made in the yard, cant make a 5 car unit from 2 4 car units temporarily. Cant make a ABBBBBBA or ABBBBA (OPTO) unit. My question has to do with APS/APU, compressors, motorized axles, logic boards.
  20. The two most remarkable things I saw at 53rd Street is, they sandblasted the concrete ceiling and left it bare. No more painting of concrete for the MTA. I think that is a good choice since in 25 years it will be all peeling and snowing paint chips on passengers. They also probably did "lead abatement" but there were a couple spots near the staircases near the wall near a wire trough that the sandblast gun didnt reach and the beige flaking paint chips are still seen. Also on plat level near the south end plat to mez stairs some of the plastic wrap used for sand blasting/painting is still there wrapped around conduit. DC Metro meanwhile is painting their concrete ceilings as a new policy. https://twitter.com/Tracktwentynine/status/846872851969953793 https://dc.curbed.com/2017/3/31/15122600/metro-wmata-union-station-paint-brutalism Also either MTA installed optical infrared fire detectors, or people counters on the ceilings. I can't tell. They sort of look like camera lenses but they aren't. Never seen them before. There is also a black ribbed, "towards exit" tile band in the platform. Like an airplane floor emg evac floor light, but just ceramic tile. Not sure if it is ADA or fire code.
  21. Lexington Avenue – 63rd Street platform level underpinned IRT 4 by bulk1988, on Flickr No real need for a surface level pedestrian tunnel. The express IRT tracks go through the top of the 63/Lex cavern. They were underpinned during construction of the 63rd street line. 1 or 2 flights of stairs going up and a 3 block long walk along side the tracks and you will walk out on the express platform of 59/Lex.
  22. I think this 75th Ave switch replacement GO is this years Hillside Ave Fasttrack. 179 street queens bound platform level ceiling got scrapped and repainted during one of the weekend GOes since previously it one of the most falling paint chips places in the system. They are doing other work, probably all Fasttrack style, during the east of 71 ave GO.
