  1. I actually saw the 10 car doing simulated stop testing at Nostrand on Thursday
  2. The NYC subreddit doesn't do much besides complain about everything. It's kind of their thing.
  3. This concerns me. These deans aren't even certified professional engineers, and we're expected to take their recommendations and intuitions as fact for "state-of-the-art? Academia is quite different from actual engineering process, and it seems like Cuomo and De Blasio fail to realize this. It sounds like it will lead to more band-aids on top of bullet wounds, like the L shutdown't. Also, as Around The Horn said, this focus on design-build and "innovation at all costs" seems to be leading us to a situation similar to what happened back when the R44 and R46 were introduced-the subway is simply too complex and too vital to sustain large-scale tests of unproven tech. This does not mean that it should not learn from other agencies, though.
  4. If it's used to its full potential, it can be a huge boon to the operations of the transit system. However, the inefficiency that NYCT currently operates with makes its potential benefits not worth the cost, as we could easily achieve higher frequencies with the signals that we currently have. It definitely has more frequency potential than fixed block, but at this point in time it's too expensive for what we achieve with it.
  5. It's already peeling at the bottom of the walls near the no clearance signs
  6. It's kind of interesting how everyone settled on CBTC as the answer. Although it absolutely has its merits, are there any examples of it scaling up to a system with as much interlining and possibility of reroute? In the interim, though, the MTA has been given lemons. They aren't making the lemonade that they could be.
  7. I notice that CBTC is increasingly described as the technology that fixes any operation and/or speed issues on the subway. I feel , at risk of great oversimplification, that a more efficient operating environment would fix a lot of capacity issues: Reprogram NTT motors to accelerate faster and to higher speeds Loosen penalties for operators that trip timers while traveling at the posted speed Only if it can be proven that they were traveling at or below said speed Decrease braking distances and control lengths Survey every timer in the system and evaluate which are truly necessary for safety Assign each dispatch tower a permanent crew so that they can learn the patterns of their designated area for efficiency's sake Use local recycle on NTTs instead of reopening the entire set Honestly these are a lot easier said than done, but they would probably cost less than and be faster to implement than CBTC for some temporary relief from our current situation. On an unrelated note, connecting IND Fulton St and Montague with SAS provisions would probably be a quick solution for Cranberry's issues
  8. Why don't they run the peak direction express on the El? It would probably eliminate or at least reduce the conga line.
  9. Almost the entire B Division is affected with this one
  10. Has anyone else noticed that service on the and has gone downhill lately? If the trains aren't crawling through normally fast zones, If not that, it's normally absurd waits to the tune of 15+ minutes.
  11. Why does brooklyn have so few artics (one artic route) compared to every other borough except for staten island?
  12. Finally caught the train with the LED screens. They are partially obscured by the poles right in front of them.
  13. Apparently a downtown train is having mechanical problems, forcing other southbound s to go local. I'm not sure if that's the whole story, though, because I just passed it and there were a bunch of officers running towards a single car in the back with half or one door open.
