just a thought, but do you think the controller handle would be moving by itself to control the speed during ATO?
No; that's primitive style automation you're thinking of. (I remember in the early 70's seeing an early remote control TV where the dial turned by itself. Of course, remote control technology would eventually do away with the dial altogether).

The controller stays in Full Service, I believe. (And if it moved itself, it would have to twist itself out of the dead man feature too).

The Jamaica line still has R42s. I doubt that they would get CBTC next. The next line could be Broadway Express after the elimination of the W and when the Q gets rid of its R68s.

The Queens Blvd. line expresses, the (E) and (F) will get CBTC after the (7) does. The (E) will be all R160 by the fall of 2009, and the (F) will have a few R160s by then too. The (F) may become all R160 as well.

I'd like to believe that, but the (7) has buku issues with signal and switch reliability, i can't imagine the problems if you put yet another system in.

 

- A

I think adding CBTC will fix the problems with the signals, since you're adding the new signaling system. The current signal system malfunctions a lot I think because the ATS system still has bugs in it.

 

BTW, when ATO starts on the (L), will the (L) use CBTC, ATO and ATS at the same time? Also, I think I got confused after reading this article about the difference between CBTC and ATO. I'd also assume that they fixed the OOS R143s with CBTC failure. Since the R160s don't have CBTC, and only run on the (L) when there are R143s OOS, they need those extra R143s to run without ATO.

Those R42's will be gone by Summer 2009, when the R160A option order 2 comes in, with some R160A-1's to replace them.

CBTC is the technology that allows ATO. ATO and ATS are functions that are enabled by CBTC. To put it in more simpler terms, CBTC would be Windows while ATO and ATS is a program that runs due to it, like Officer or Internet Explorer.

ATS has nothing to do with CBTC. ATS is currently running all of the IRT (except north of 149/Grand Concourse & the Flushing Line) as well as the (L).

There are multiple generations of CBTC systems based on multiple variations and configurations depending on the providers and operators.

 

A CBTC can provide different levels of railway automation, grouped in the following major functionalities:

 

- ATP: Automatic Train Protection;

- ATO: Automatic Train Operation;

- ATS: Automatic Train Supervision.

Simply put, CBTC involves computer controlled signals. ATO involves computer controlled trains.

ATS and CBTC are two diffrent systerms but do work together. Some trains will be operating in CBTC ATO come Tuesday but not all trains they got R143 with CBTC issues may be operating on CBTC Bypass and all R160 running on Bypass. So some (L) will have a T/O operating while others the T/O will just sit there and hit a button.

ATS is RUINING most of the IRT as it has severe glitches in it's implementation. CBTC has it's own issues on the (L) line because all rolling stock must be properly equipped for it to run properly. The idea is to have the system to be totally set up to have CBTC and/or ATS manage the movement of trains and signals system-wide. From where I stand the corporation behind it hasn't shown me that it can successfully implement it. IIRC the whole system, CBTC and ATS was supposed to up and running around 2003 or 2004.

I'll see your two links and raise you three (and none of them are wikipedia articles). You'll see that while all five talk of ATS in the IRT, only the last one even mentions CBTC. Now, I'll try again - ATS is operating in all of the IRT (except where previously noted). CBTC is not operating anywhere in the IRT. Therefore, ATS is not a subsystem of CBTC.

Keep in mind that when you have CBTC, all trains that run on the route have to be CBTC-equipped.

 

If you were to have the (E)(F) run CBTC, then the (A)(C)(R)(V)(G) would also have to be CBTC.

 

False. When the E and F go CBTC, most likely it will be the Queens Boulevard Line express tracks. So your quoted lines won't be using CBTC, unless the system goes on those lines as well.

I bow gracefully to your knowledge. Maybe one day I'll see you in school car.

Is it possible to switch off the CBTC once in Manhattan?

Since you mentioned the company behind the two systems, their proposal was to use the somewhat connected technologies (ATS and CBTC) to allow better spacing of trains and speed up the movement of those trains, correct ?. Since the (L) and (7) lines as a rule do not share trackage with other lines they were to be the test platforms for CBTC. The IRT, being the smallest division, was given the dubious honor of being the test area for ATS. A few years ago the powers that be recognized that the whole Lexington Ave corridor as well as the Queens Blvd corridor were operating at capacity during the rush hours. Simple physics 101 should have shown that NO technology could increase the capacity on these lines but the capital was already in the budget and had to be used. So first thing is to strut it (CBTC) out on the (L) line, which had the room to add trains, and declare it a success. Queens Blvd is a horse of a different color. Why not shorten the (G) line so it won't get in the way? That'll work, right ? If the (G) ran to it's original terminal, along with the (R) and (V), the system wouldn't work would it ? On the Lexington Ave corridor with the ATS system you have problems at Bowling Green station where the (5) terminates. Solution, send all (5) trains to Flatbush Ave during the midday hours so the Central Business District doesn't see the back-ups ,and then call that system a success too. Never mind that all the Brooklyn riders on the IRT can see through the smoke and mirrors and know that this ploy is a gimmick too. Perhaps someone on this forum realizes that both systems were supposed to be up and running years ago yet they're still in the testing phase in most locations. The people who signed off on these ideas have retired or been sent to the boondocks of (MTA) land so they won't be heard from again. This technology may be the future of rapid transit but it's not ready for prime time in the Big Apple yet. Just my two cents.

The (G) is being cut back because of all the conjustion coming into Continenal. During Wkend nights when you have (G)(R)(V) service its backed up to Woodheaven and beyond sometimes. Don't let a person refuse to leave the train at continenal there is never a Police officer around and all service just stops with no reroutes since they afraid of delaying (E)(F) Express service.

Would it be better to extend the (G) to 179th?
