CTA 'L' - CRRC Sifang 7000 Series Cars Performance Testing on the Orange Line
HTML-код
- Опубликовано: 7 сен 2024
- The next generation of CTA 'L' cars are seen here testing; making simulated stops along the Orange Line. This was taken December 30th. Every new rail car series has to go through a variety of tests to ensure they are safe for passenger service. This includes making sure the rail cars can handle being able to go through certain stations, curves, tunnels, 'L' structures, .etc. In this video they are specifically testing the hydraulic suspension and making sure the cars lower properly to platform level.
This was also a good opportunity for the 7000s to test in winter weather as there was a snow storm the night before. The screeching you hear are the train's third rail sleet scrapers, which scrape ice off the third rail so that the power collector shoes don't get damaged.
CTA's 7000 Series cars, being built by CRRC Sifang America, will replace CTA's 2600 Series cars which were built between 1981-87 and are currently the oldest in the fleet. The base order for the cars is 400 cars. If all options are picked up for 846 railcars, the 7000 Series will also replace 3200 Series cars, built 1992-94 by Morrison-Knudsen. The cars are expected to run on the Blue, Brown, and Orange Lines.

0:01 The intro with the "Venta Card accepted" sound was my favorite part for no reason at all
CTA has interesting ways to deal with their third railswhen icy.
I would have thought the third rail would stay warm just by the electric current running through it...
The front of train looks beautiful nice color scheme definitely cta material also very jealous of the motor man operating the el train!!!😀
Nice new train but the squeeking is killing it.
@VERNONBLVJSCSONAVUNE On the 7 train and 6 train They didn't have the scrapers down - if there's that much noise from the third-rail pickup shoes, they've got to find a solution.
Rail squeal is a screeching train-track friction sound, commonly occurring on sharp curves. Squeal is presumably caused by the lateral sticking and slipping of the wheels across top of the railroad track. This results in vibrations in the wheel that increase until a stable amplitude is reached
2:33 Hinting out that new “Doors Closing” announcement.. Sounds so vibrant on the 7000’s even though it sounds very similar to the ones we currently hear
Cause it's the same doors closing
Yeah that's the exact same announcement.
It only sounds clear because the train is new.
@@blue9multimediagroup I think they will fix that later
@@keyshawnscott12
Fix what? There's nothing wrong with it.
@@blue9multimediagroup your right
Thanks for peering in the window! The seating arrangement looks great
They taken it old school how it used to be in the 80s
the 7000 series is Awesome, I Love the front of the train 🚇🚉👍🙂
New cta rail cars look to be a bit of most of the past rail cars 2200 series windows 2400 series front end of rail car body style 2600 series and 3200 series chains at end of car and corrugated sides also they have the cta color scheme I remember the days of the stripes on the sides of the el trains definitely a train car to fall in love with if you are a series rail transit buff !
Great video!! Pretty interesting technique of how CTA combats icing on the third rails. Greetings from NYC
@VERNONBLVJSCSONAVUNE On the 7 train and 6 train what?
Nice can't wait to see more! I personally can't wait to flim them! :)
@VERNONBLVJSCSONAVUNE On the 7 train and 6 train 🤡
@VERNONBLVJSCSONAVUNE On the 7 train and 6 train Stfu little boy
@VERNON 😂😂
Had to click the moment I saw that notification. Thank you for the updates
Those trains sound squeaky as hell. Nice color scheme though.
Seeing these brings a smile to my face
I hope they get rid of the "bathroom area" on those trains. Last time I was in Chicago, some of those trains stink.
Well those are the homeless that ride the train
I cant wait until the Chinese cars we ordered come to LA. Lookin good CTA!
I wonder why CRRC and Bombardier went to all that effort to design and implement a kneeling system for the trains when they could’ve just built the trains with the floor height a couple of inches lower... that would’ve saved them the money and effort of designing and maintaining a hydraulic kneeling system. Seems a bit like overkill IMO.
Also, why were the marker lights on at the back of the train at 8:58? Shouldn’t it just be the red marker lights, not the orange line lights as well?
The kneeling system was implemented because wheelchair-bound passengers can roll off the train before kneeling when the train is somewhat raised to allow them to exit with ease. When the train kneels, wheelchair-bound passengers can roll onto the train in much the same way, using gravity to their advantage. I've heard that the 7000 series have alignment sensors to detect the exact platform level and align to it, which would eliminate the problem of some platforms that are very much higher or lower than most others on the system.
@@rileycoyote4924 that makes sense, but I’m wondering why they didn’t just build the trains with a floor height that was just a couple inches lower than the previous stock so that it matched the platform height at stations. That way the trains wouldn’t need to kneel at all and it would be more like other rail systems where the trains’ floor height is at the same height as the platform. It just seems like an extra mechanical system that will require maintenance and will break over time.
@@OliversElevators Every platform is different as far as height. Some platforms are uneven. There is no way to design a train with a "perfect" floor to platform level.
@@ChicagolandTransit lol that’s unfortunate. This is the only rail system I know of that has trains that kneel like buses. They’re probably never going to be able to get rid of the kneeling feature on new stock until they re-level all the platforms. Now you need to get New York to get trains that kneel so they don’t have such a vertical platform gap.
That light defect is what we were worried about having only 2 lights to run markers on instead of 8. Why CTA even uses red for route designators is head scratching.
I see the indicator lights on 7000 rail cars on the 🧡🚇
does it drive with the brakes on or why does it squeak like that? Or have they forgotten the good old WD40?
You probably didn't read the description. The reason why it's squeaks is the scraper on the 3rd rail.
@@jamesf791 wrong rail squeal is a screeching train-track friction sound, commonly occurring on sharp curves. Squeal is presumably caused by the lateral sticking and slipping of the wheels across top of the railroad track. This results in vibrations in the wheel that increase until a stable amplitude is reached
@@kevinwilliams2643 I’ve been listening to squeal on the L for 40 years and riding them daily for 16. NO train squeals that badly on straight track pulling into these stations until these new trains hit the rails.
I wonder if the blue color on the front of the car (once in service)?will designate blue line, and cars assigned to red, brown, green etc lines will have front ends painted in colors of their lines. (I read they will be assigned first to brown, orange and blue).If it’s just for decoration, would prefer classic CTA mercury green or the later dark green. Whatever, They look great
CTA will not waste money repainting cars according to what line they'll be assigned to. That's why LED colored signs exist. CTA has used the color blue on their rail and bus vehicles for years now. It gives the train a very modern look.
You do know that switch lines on a regular? Some lines share equipment so having them painted in a line color would be out of place on other lines.
Also, CTA corporate colors are mostly blue so it makes sense to have that on the front. Plus it pops out to the eye. This is not 1960. There is no need for green and orange anymore.
@@ChicagolandTransit makes sense.
@@blue9multimediagroup true
If one day I decide to do my Chicago travels again, you and I should collab.
Since the 5000 series can’t fit on the congress branch, I’m assuming the 7000 series can, are they lighter?
That's a question that can't be answered until CTA finishes testing the 7000s.
Some of those multicolor markers are hard to tell apart. Need to work on the color filters.
The fact that the front color doesn't match the color of the subway line deeply upsets me.
The side of of the new train could be better the front LED lights look nice though.
I wonder why they kept the old design and not used the designs by CRRC.
I rode the orange on the 30th and saw one of these cars stopped at Western. I was wondering what it was.
I love these cars, but it would've been perfect if the cars had the fronts all colored to their specific lines instead of all being Blue!
A major difference between CTA and other transit systems is that all of its rail cars/lines are pretty much universal; all cars can fit everywhere within the system. CTA will more than likely not spend money to repaint every single rail car that has to be reassigned to another line.
@@ChicagolandTransit I see, I see. I guess that makes sense convenience wise and cost probably too. In a perfect world, it would've been great to see that. It would give each train it's own personality and flavor, and also fit their color coded line system.
Thanks for sharing. I'm curious if the 5000s could be married with the 7000s?
No only same series cars can be in a consist.
@@kevinwilliams2643 3200s and 2600s could marry with each other, same with 2200s and 2400s and 2600s. They could all couple with each other
Need to do something about those brakes these cars should not be making those noise when they brake.
That's normal. Have you never heard brakes screech before? Look at New York's trains and how they stop when they come into a station.
Not to mention, as stated in the description, the squealing is mostly sleet scrapers meant to knock ice off the rails.
I drove for the MBTA Blue Line trains and the ice scrapers never made that sound
@@tonymento3017
Might be different models.
Not to mention, CTA uses top contact third rail with the shoes hanging down from the trucks as opposed to the usual side contact which means the weight of the car in Chicago probably presses down on the scraper slightly.
Not sure if this is why, but it makes the most sense.
@@blue9multimediagroup the MBTA Orange and Red Line cars have there third rail ice scrappers next to the third rail shoe which rides on top of the third rail the only cars on the MBTA that does not have third rail ice scrappers is the Blue Line the third rail is in a tunnel from Airport Station to Wonderland Station is over head 600 volt wire
It sounds like the train is squeaking
Read the description
Ahh my bad, thanks!
Did they re use the body of older trains? Cause they look exactly the same, just with new front ends
No we did not
The 7000 series interior looks so outdated they should’ve made it different
Can you explain in what ways the interior is outdated? I have pictures of the interior and I can tell you it's as modern as the R211s that are coming to your city.
@@ChicagolandTransit Dull colors and continued use of old-fashioned seats that look like the ones on a RTS bus (as opposed to a modern bus rapid transit vehicle).
All that squeaking noises
Train look thin
so they got billions of dollars to design and build new trains but made it look almost identical to the last one?
This is the Chicago L. What more do you expect? It's called modernizing but keeping the traditional design of an L car.
@@ChicagolandTransit yeah New York kinda did the same thing except the r211s actually have a new interior and new front faces
Dated and same old garbage design.
Stfu bruh
All the American trains seem to be like that. Sometimes I keep asking, why can't they make the design so much more Modern? The Siemens metro in Warsaw looks nice, the trains in Paris look amazing! Even Montreal has better looking trains and their trains are about a few years old. Not the Mr-73s but the other newer ones I just can't think of the type right now. But I still love trains.
