What is CBTC?

Communications-Based Train Control is bringing greater capacity and improved safety to the New York City Subway.

[@robmartin7657]

This is a great and informative video. Next time though lower the music in the mix. It's drowning out the info and bit off putting.

[@A278PlusPi-Legacy]

I haven't realized until recently... but, thanks for installing CBTC on the 7 train service! It makes me love the 7 train service even more. Although the R62As have gone to the 6 train service, these old trains are still here! The R62As are now under the assignment of the 6 train service, and if I needed to ride these old trains for fun, I can just ride on the 6! ...and if others want to ride on the R142/As on Manhattan, they can ride on the 2, 4, and the 5 trains!

[@joshuawaterman7987]

can't believe this video is from 7 years ago and now in 2024 we are getting CBTC on the 3rd (G) and 4th (F) lines

[@ACLTony]

Would be so cool if the MTA would install the CBTC equipment on the museum trains which, currently, are not permitted to run on CBTC lines.

[@aqua2poweros699]

sadly its impossible because so called SMEE's are too complex and old to have CBTC installed. But NTT's (trains made from 2000 to present day), can have cbtc installed. WHen the R211's finally come to the 8 av line, 8 av will have CBTC installed and their old R46s (a car that can't have CBTC) will be retired.

[@user-un6xf6xj8w]

Does CBTC maintain a 120 second tracking interval? Is IATP available?

[@LIRRSBSPRODUCTION]

I miss my R142as on the 6 I want my R142as so Lexington Avenue can go back to being just R142as and R142's

[@pjay9875]

Same here

[@LIRRSBSPRODUCTION]

I actually like the R62 because its made from Kawaski i dont mind seeing just R62 because its made from kawaski but the R62A gotta go AND i love the R142A so much because i been living along the 6 line since 2000 so its hard not see the R142A's anymore

[@fristi60]

Actually R143 and R160 are also made by Kawasaki

[@IsolaticYT]

R62 type trains have technical equipment which is old and harder to maintain, in contrast to the newer train cars. I don't have an exact reason why MTA are considering in replacing R62s with the newer R142As, which has already been done with the R62As being replaced completely with R188s.

[@douglaswells6679]

I like the R 62 on the 3 line but not on the 6 line so now this make sense that they took out half of the R142 A and transfer it to the 7 line because the 6 has no CBTC

[@GPT-X938]

good video, music is a little high

[@albertino100vasche]

Very clear !!

[@Motorman_G]

Very cool

[@physetermacrocephalus9986]

Did anyone notice the old mta logos on the trains in the video?

[@ROCB211]

Yep

[@videonut1988]

The “M”? I noticed!

[@tomasrvigo]

Yes, I was about to write that! Fond memories brought them to me...

[@Chris-zs5qb]

It wasn’t MTA back then

[@amoora2235]

ok, this is urgent, what did use to animate at 0:25

[@acep170]

Just like CTC for a class 1 trains but MTA signals are need way more improvement. They should look into how Shinkansen and the AGV systems work

[@bidhanchakrabarti1998]

The video is very informative but the background music is too loud

[@meantoneorgan]

CBTC and "fixed block signaling" are not alternative concepts, and the fact that NYCTA's own engineers don't know this should tell you something. CBTC simply means you use a wireless communications system to give the train its speed command. It may or may not know exactly where the trains are and might not efficiently separate the trains. A moving block system is an alternative to fixed block signaling, but is not necessarily communications-based. Also, a moving block system is not necessarily of higher capacity than a fixed block system. Again, that NYCTA's own engineers don't know this should tell you something. For instance, London's Victoria Line has fixed blocks but the minimum platform reoccupation times are in the 40-50 second range, far shorter than NYCTA's L line. That's because what really matters to capacity is not whether the signaling is fixed block or moving block", but other aspects of the design, primarily the train's spare braking capacity.

[@SpectreMk2]

Very useful comment. I would add that what is being said at 1:00 is completely false. Fixed block signalling can also allow a precise speed control of the train when used with transmission lines along the track that indicate the speed profile to follow and even accurate stopping points at stations (very useful when platform screen doors are used). The technology has been used in Paris since the 70s and has since been improved with VAL and Meteor automatic train control (on line 14, also in Paris).

[@brianna_lynch]

Hopefully this will help the delays decrease!

[@johnmor3541]

Jacob Edward Lynch just look at the L thats the only line with cbtc

[@videonut1988]

Johnny M, the only BMT line with that system. Hope they’ll have it on the rest of the BMT/IND and IRT Lines.

[@TheDavinchoo]

Why did they Reupload

[@CrosstownXpress]

Actually, this video seems a bit different than the first video.

[@TheDavinchoo]

Kirby Flame they just took out the Explanation or what is CBTC from the video from July 2015

[@tucstwo]

1:29 How many $50/hour union workers does it take to screw in a light bulb? Apparently... 6, 1 to screw in the light bulb and 5 to watch. Gee, I wonder why our subway fares go up?

[@bishlap]

It's not as bad as u think, unlike con-ed where it takes 1 man to dig a hole and 5 to watch, ain't UNIONS great? Anyway, The MAIN REASON fares are high and going higher is every G-Damn politician in NYC has given the MTA the greatest pension in history. MTA pays out more in salaries and pensions than it takes in.

[@42luke93]

Guys what if they are learning how to do something? Then they will do it on their own later...

[@aqua2poweros699]

Its been $2.75 for a while now and tbh I'm glad its not more expensive. I mean its now $8 for one Airtrain ride

[@Ashes449]

I heard that R143 and R160 is already equipped with CBTC idk about the R179

[@aqua2poweros699]

R142, R142a, r143, r160, r179, and r211 are all able to be equipped with cbtc

[@zrinzoj]

when will this be installed on the 7??

[@johnmor3541]

Brenden Resnick now done

[@britishenough7690]

Done and is calibrated. Trains every 1 and a half minutes during peak hour.

[@JustSimplyLunar]

Next thing you know is MTA thinks about implementing ATO (Automatic Train Operation)

[@TheRailLeaguer]

PrimingFUME The MTA is dreaming big. Meanwhile the union is also dreaming big... to stop ATO and one person train operation.

[@rodrigodelprat]

@@TheRailLeaguer Meanwhile London has had ATO for over 50 years (on the Victoria line).

[@TheRailLeaguer]

prodigalretrod I’ve heard.

[@michaelmorales1475]

The (L) Train has ATO.

[@Xycopixie]

I am confused, can't we just stick GPS trackers on each train and track them through an app in the meantime (like what we have for buses with MTA Bus Time). This may be tricky for the underground sections but won't this temporarily circumvent the problems with not knowing where a train is?

[@XxLiLGiJoE17xX]

SowMuchMore no you cannot do that. Are u trying to kill people? They need to use technology that runs through the train, the third rail, and signals. If you put GPS on the trains, how are they gonna know where trains are underground? Do u have service on your phone when you're in tunnels? What about when trains cross under the water? That's completely unsafe. This is the best solution and I don't understand how you are confused, the video clearly explains what's going on.

[@britishenough7690]

SooMuchMore The subway is mostly underground. GPS doesn't work under rivers, last time I checked. And also, the space between 2 (7) trains is 7.5 minutes more when CBTC wasn't on its line (trains every 8.5 min to trains ever min)

[@DANNYN224]

We need this for the f train jamaica 179

[@realniggsolo]

That's one of my home stations. Let's not intoxicate it.

[@TheRailLeaguer]

The Queens Blvd Line (for the E, F, M, and R) CBTC project is in the final stages of implementation up to Union Turnpike and the section to Jamaica-179th Street and all eight relay tracks are in the process of getting it with no timeline.

[@SpectreMk2]

What is being said at 1:00 is completely false. Fixed block signalling allowd a precise speed control of the train when used with transmission lines along the track that indicate the speed profile to follow and even accurate stopping points at stations (very useful when platform screen doors are used). The technology has been used in Paris since the 70s and has since been improved with VAL (65 seconds headway between trains in regular operation or 55 trains per hour per direction) and Meteor automatic train control (on line 14, also in Paris).

[@cm770011]

Why da fuck my train late today

[@Roboboy]

Nice revisit of CBTC, but whoever's writing these scripts really needs to work on simplifying the language used in these explainer videos. If it's aimed at the public, we shouldn't be hearing RCC speak like 'wayside' or unnecessarily advanced English words like 'ancillary', 'warrants', 'implementing'. If I recall, the Operation Track Sweep explainer video seemed like it had a good review of the copy to ensure it used plain, simple language to get the point across.

[@dmcmanam]

I thought it was very informative for an adult audience. I think it is appropriate to assume a certain level of education for a topic such as this.

[@madeinczech]

Music is disturbing, too high

[@LIRRSBSPRODUCTION]

CBTC could of went to the (4)(5) and (6) too but instead of converting R142as into R188's y'all could of well you know what forget CBTC (4) train should have R188's (5) trains with R142as (6) trains with R142as Come on MTA almost everyone who takes the 6 train is still fighting for there R142as and there not gonna stop until you give them back so MTA expect more comments like this

[@pjay9875]

We need our R142A back on the 6 line

[@donnallgreene1378]

Milton R142AProduction the 7 needed it more

[@pjay9875]

MCSM PRODUCTIONS sadly

[@TheRailLeaguer]

LIRR SBS PRODUCTION Flushing needed it more. The signals there are older and the neighborhoods it serves are becoming more popular and undergoing changes. In addition, the R62As were transferred back to the 6 line to increase service on the line during rush hours and end the chronic overcrowding and long dwell times that currently exist on Lexington Avenue. It also improved 2/5 and 4 train service since the transfer of R62As meant that there were 20 R142As freed up for 4 train use, which freed up some R142s for the 2/5 trains. As a result, most of the IRT now has increased service, which is great for me since I felt like I’ve been waiting forever on the Brooklyn IRT for a train home after 7:30 PM on the way home from college.

[@TheRailLeaguer]

P Jay You need extra 6 train service to end the chronic overcrowding and long dwell times that currently exist on Lexington Avenue.

[@satheeshrasineni8215]

Please reduce the background music..so that we can get the proper info which is in video

[@kellymoses8566]

At the rate the MTA is going CBTC won't be installed on all lines until 2100

[@kingstonbatista3009]

bring the R142A back to the 6

[@AaronJrBrundidge]

There is one remaining, the rest is in the 4 train

[@IsraelCube]

Yes please.....we need them badly.....

[@TheRailLeaguer]

Marc Lowenthal What you need is extra service on the 6 line and putting the 440 R62As on the 6 accomplishes that. No need for frills and aesthetics when service reliability and frequency is the most important need here.

[@seanho7418]

It caused 2 trains crashing into each other in Singapore 36 were injured What bout this

[@TheRailLeaguer]

Sean Ho There will be safeguards to prevent something like this from happening.

[@aqua2poweros699]

The 2 line don't have CBTC on their lines yet

[@i_am_a_toast_of_french]

that's why ctbc is implemented on deinterlined lines first like (7) and (L)

[@andrewfischer556]

The last quote in this video is questionable ... MTA says "we can provide more trains per hour when ridership warrants it" - No, they can't. They don't have enough electric power to run more trains per hour. MTA would have to fund another capital project another $100,000,000 to $4Billion investment to add more power feeds to the rail lines, currently not funded, not planned, not designed - plus, where will all this power come from on the grid ? NYC and NYS government is already creating laws and policies to overload the electric grid. I'm not saying CBTC is bad or it shouldnt proceed, but dont make false claims that CBTC allows MTA to run more trains per hour

[@NYCyclist101]

The work is taking years because the MTA works on only one portion of the closed line at a time. If workers worked at multiple points simultaneously, it would cut the closing time to a fraction of what it is. Why doesn't the MTA do that?

[@TheDavinchoo]

Brian that will interrupt Service more

[@NYCyclist101]

How? For example, if the 7 is shut down between Queensboro Plaza and 34th Street-Hudson Yards stations, why couldn't there be crews working at multiple places along that stretch?

[@TheDavinchoo]

Brian It takes alot of crew men to work on certain Stretches of the line.

[@britishenough7690]

You can't shut down an entire line. The lines that are getting CBTC are the MOST crowded ones in the system. (L) and (7) trains already have CBTC and rumor has it that the MTA will work on putting CBTC on the (6).

[@tong.clement]

So grateful that the Hk MTR managed to pull off the east rail line’s system upgrades with almost no closures at all (only working 2 hrs a day at midnight) 🙏

[@beback_]

Didn't really explain how CBTC works.

the R line is rely terible the trian is always late and runs with delays fix that shit

[@robertgomez1833]

and bring back the brown m trian
