From my experience, the Yellow line is either 7ks or a mix of 2 and 3k series. Don't recall any 6ks for awhile now.

Or are you changing the capacity of the line by running four six car trains instead of two eight car trains?Well at least the 6 car trains might start stopping in the center of the platform again. On a related note, I always thought WMATA could run 4 car 7000series mini trains during rush hour to augment service, while still keeping operating costs lower. No idea if thats possible with signal system or WMATA rules, but I would love some outside the box thinking to break up those awful 8min headways.
@railtransitops: The noise issue was fixed with a redesign of the wheel angle in relation to the rails. ~RB
