If you check Goggle Earth you can see that they have erected a new signal mast just south of the Yard 10 switch on the main. Is this not for an interlocking being placed at the junction of the Yard 10 lead? It sure looks like it.

Fundamentally, rebuilding the Grand Junction for mainline passenger rail is a terrible idea. It's a really roundabout route with half a dozen closely-spaced grade crossings on busy streets. Rebuilding that stretch of the Pike to allow for an eastbound connection will be expensive and disruptive enough (if it's even possible); once you start talking about grade separating it through Cambridge, that gets spendy enough you might as well build the North-South Rail Link and have a much more useful connection, and then you can convert the Grand Junction to light rail.

Those signals you see at Washington Street:

1) These are the new distant signals erected in 2018 related to the retirement of Somerville Jct and the installation of Tufts Interlocking.
They are temporarily out of service due to the Washington Street bridge replacement project. See below.

2) The other signals you see are temporary signals in lieu of the signals mentioned above. These were done for Phase 1 of the bridge
project which shifted the Lowell mainline way over to the west side so the east "half" of Washington St can be demoed and replaced.
Once that is done, the Lowell main will go back to its final alignment on the east side and the new signals referred to in #1 go back
in service.

Though they should, I am not sure they will change this to an interlocking for the Yard 9/10 lead.

No it isn’t. It passes right through a densely redeveloped transit area which serves as a destination to a significant chunk of the railroad’s ridership. If fluid traffic flow was a concern we wouldn’t demolishing its supporting infrastructure like the Sullivan, Casey, and McGrath highway overpasses. In an area like Kendall Square and Mass Ave, the automobile should not and will not be the primary mode of transportation. That stretch of the Pike is being anhialated anyways as previously mentioned so cutting in an eastbound leg while that’s already disrupted would not be all that impactful, not that I believe this will happen but it absolutely should.

NSRL isn’t happening. Sure, people keep wasting our money on studies to push for it but it gets rejected every time and we’ll be arguing about it for all eternity. As it stands it isn’t happening, so why would we write off potential improvements and expansions for hopes of a project that can’t gain any steam in the first place?

I want to add that the newest (and final?) plan removes the ugly Mass Pike viaduct and replaces it with a new ugly Storrow Drive viaduct! If the Mass Pike was lowered through the entire narrow "Throat" area, not only would it be possible to build two wye bridges for the Grand Junction over it, it would also be possible to put Storrow Drive over it at ground level. That would greatly enhance the look of the area and probably also leave more room along the river's edge for bike paths, walking trails and scenic vegetation.

Check this out for an interesting rendering of a proposed plan for the west end of the Grand Junction:
