Most metro riders know by now that metro has ordered new rail cars to replaced the oldest ones in the fleet. These are the "7000 series" cars and they are more high tech than earlier models. They started service in April of this year.
For anyone wondering why after 7 months you still don't see them very often:

Finding flaws in production and mitigating them is part of the japanese production technique. It may lead to things taking longer for delivery sometimes and issues early on, but a better quality product down the line. Continuous improvement is a much better ideal than the crappy older metro cars.
I can see this explanation, sometimes faults are not found until it's in actual use, you can test things to death and still not find issues.
Sadly this continuous improvement ideology is not at the heart of metro itself. They seemed to adopt the opposite philosophy of continuous incompetence.
Either way, they will likely ramp up now they now the issues.
7000 series can't be mixed with other series cars so on most lines you won't see them for a while.
They are on every single line at this point, but the Silver and Red line with get them first. Silver because it is a new line that needs more cars, and Red Line because the cars on the red line are the oldest in the system (it is the oldest line). The green line will get the new cars last, since it was built last.

Do cars stay on the same line forever? I guess that would make sense since I always see lots of 6000 cars on Green Line.
Not to nitpick, but I read yesterday there are 5 trains in service. I think the Silver Line is the only line without a train.

On the red line, they do. But cars on interconnecting lines do in fact get pooled.
The green line is the newest of the lines outside the silver line, so they are the cars least likely to be replaced. They pretty much have 5000 and 6000 series cars.
The Orange/Blue/Silver do share cars, especially the orange and silver lines.

This is not true.
All the lines have a mix of 1000, 2000, 3000, 4000, 5000, and 6000 series cars. Every line has 7000 series cars except for the Silver and Yellow line. Cars move between ALL lines based on demand and need for maintenance.

I very rarely if ever see 1000-3000 cars on the Green Line. Usually 4000-6000 cars.
Orange/Silver is full of the nasty 1000 and 2000 cars unfortunately.
So a new 7000 series train entered service on the Red line this week. This is the 6th new train to enter service since April.
Yay.
