7000-series - Delivery & Updates

[midway_737]

I am pretty sure they only run the 7000's on weekday's since they run during the morning to UIC, but I could be wrong.

I spotted a 7000 series train around 1130a leaving IMD  heading west towards Forest Park on Thursday.   That said. I don't think they are running weekends yet.  We probably need to see a few more sets of 7000s in service before we see them on weekends  and maybe a bunch more before any get assigned to the Forest Park yard.

I’m not aware of Forest Park Yard having any 7000s assigned to it yet, or at least I can’t see them from the Eisenhower.

And if anyone is still following the Orange Line set at Midway, it’s still there, but one of the cars now has a blue light. This might have thrown a wrench into the training plans there.

I saw three sets of 7000 series today at the rosemont yard.

It's funny how I posted back in April 2021 on this thread that in my opinion the Blue line will be the FIRST to officially run the 7000 series in service when I noticed a blue line route map above the doors while watching a test run video on youtube in 2021 and then getting attacked/called out on here for doing ?? Hmmm ???

Waiting on some apologies now  ? ??

A map above a door in the early stages of revenue testing isn't or wouldn't be indicative of what line would receive new cars first.  The 5000s had Red Line maps when it was the first line to test those cars but the Pink Line was first to get them assigned followed by the Green Line.   

The Blue Line should have been the first line to get them because it has the oldest equipment in the largest numbers.  While the Pink Line didn't have the oldest equipment when it was the first to receive the 5000s, CTA decided to ease them into service 

  For that reason,  I stated the possibility of the 7000s going to Orange and Brown first for teething purposes and the fact that the Forest Park branch was in poor shape.  Remember that the CTA cited poor track conditions for not assigning 5000s to the Red Line until they could rebuild the Dan Ryan Line.   

I didn't see the YouTube video where you were first to say the Blue Line would get the 7000s first or where you were ridiculed, but if your assumption was based on a map over the doors during the early stages of testing, you had that coming.

In addition to what @artthouwill said, the first 10 cars were supposed to be tested for one year on all lines, and there are videos of the cars on the Orange, Green, Purple, and Pink lines. The Purple Line car has a RPY sign over the door, so there.

[Bus1883]

Now that we started the new year off into January could we see another 10-14 cars sometime this month? They stated 10-14 would be the range each month for deliveries. 

[Jackson232]

I bet the cta is going to give the different lines 7000 series trains, one by one and not just all at once. I think that because since they’re pretty much done testing, only the blue line has it so I bet it’s gonna keep going one by one.

Due to supply chain issues and China's zero-covid policy, production might just slow down or worse, be halted.

Again "conventional wisdom" based on no access to the CRRC production control system. By this logic, better not expect a new iPhone 14.

The latter was lifted, so at this point, only a matter of time on supplies (aside from speculation).

That’s good that it was lifted. Hopefully the process will keep going good.

After the blue line has all there sets of 7000 series cars I wonder what the next line will be to get the 7000 series cars.

Well i just picked up a MAJOR clue !!

 

Looks like the 7000 series are heading first to the BLUE AND GREEN lines !!

 

Check out video Time stamp 0:46       The line route map inside has the "Blue line" and next a GREEN line on them 

 

Also first time I ever seen "Howard" sign with a blue colored background lol

It was a test.  There is NO EVIDENCE HERE to suggest the Blue and Green Line will get these cars first.  That doesn't mean they can't  but the video suggests nothing. 

 

[Jackson232]

I wonder when the will give all the sets to the blue line

From what was mentioned CTA will assign the first 400 cars to the Blue Line. Remaining 446 option cars will go else where between Brown and Orange Lines.

Ok thanks

[Jackson232]

I’m not surprised that the brown orange and blue line trains are getting the first sets of cars because they don’t have the 5000 series.

I spotted a 7000 series train waiting for departure from the Forest Park station around 3;45PM yesterday.   Seems like there's a vonsist running the full route throughout the day.  Perhaps the other two consists are still on the a.m. rush UIC short turns?

Hopefully next week we will see an additional consist added.

[Jackson232]

I bet it will keep going more consistent as time goes by.

Today I rode 7011 as the lead car.  This consist had consistent troubles with the doors not opening at stations.  It would take 30 seconds to a minute before the operator could actually get the doors to open.  I'm guessing that the doors don't open until the cars lower themselves.   It was very cold today and it felt like the cars had trouble lowering 

  There were a couple of times when the doors easily opened.  This appeared to get better as we went along.

I should mention that train had to be " started" at Forest Park.   I don't remember  that happening since the 7000 series trains were in service.   Without the electric motor running, is it possible that some of the air lines experienced some freezing causing delays in the car leveling system  and as a result,  causing the doors problems?  There weren't any operational issues as far as braking was concerned.  It seemed strange that a train would be shut down, especially when temperatures were below freezing.

I haven’t rode the 7000s enough to observe how each of their subsystems work as the train goes along the route, but I don’t know why the train leveling system would dictate the operation of the doors, unless there was something seriously wrong with it. On the 5000s the doors still open and close based on what the train operator is telling them to do, but the train doesn’t raise and lower. You can see this when a train is boarding at a stop and one car looks somewhat higher than the other.

The one time I’ve been on a 5000 Series train where the leveling system was a major problem, the entire train was unloaded and taken out of service. The rear car wasn’t level, like a less dramatic version of those tilted cars with hydraulics. I could see the car body at an angle, but I don’t know how the car or it’s doors were behaving before the train was taken out of service since I was riding several cars ahead.

I don't know how the leveling works, but Chicago cars have not had compressed air since the 1947 PCC streetcars (remanufactured into the 6200 series rapid transit cars), and air springs that were standard on Budd trucks were not used by CTA. @artthouwillwas talking about leveling to the platform, but I would guess that it is hydraulic.

However on the 5000s the cars raise back up once the train starts leaving the station it’s not like how the 7000s are, once the doors are closed the cars raise back up when standing still that the 5000s don’t do. I’ve also noticed some 5000s don’t lower down onto the platform height once the doors open while a few still do, maybe it has something to do with the hydraulics or suspensions having issues when failing constantly.
