Doesn't seem like a lot of other people post on this thread but there has been actual progress on the purple line for those that are right nearby.
They poured a big part of the bridge over Rock Creek and they dug out the entrance to the Plymouth Tunnel. They are actually doing more than utility work left over from the state run period finally.
The state website is worse now if that was possible, but the "social" media steams can give some pictures of the progress. I suspect they will make their planned service date as the contractor taking over knew where most of the "bodies" were whereas the original contract there is always a bunch of unknowns.
Sadly still years away but at least they are finishing the structures much more now. It would be nice to see them finish the test track over on the PG side of the line so we can see them test the train sets which are basically done and sitting in NY. Its almost certain that section and the overhead line for it will be the first finished. My guess is Bethesda will be the very last thing done as that is the most complex part of the project, though the shaft is just for elevators so perhaps it is less complex than I think to make that connection underground.
With the 7000s slowly coming back and Silver open to the end this is the next thing after Yellow reopens the bridge. 2026 though.
