None I believe. Don't forget it was a four track ROW originally and there was a junction for the Saxonville branch that split off just west of the station too.

As far as reversing the undercutting, there always was a drainage problem here so maybe. Don't know if future electrification is being allowed for.

No takings that I know of. The cut (built in the 1890s) was built for 4 tracks (north to south, 5, 3, 1, 2) plus a platform on the south side. From the 60s until now, the two southern track slots (1 and 2) were in use, with the westbound platform on the northern center track slot (3). The new configuration moves the westbound platform to the northernmost track slot (5), with the northern center (3) and southernmost (2) tracks in use, and the southern center slot (1) reserved for the future third track.

Yes the freight under cut on track 2 has been "removed".

A good buddy of mine is the road foreman for the east end of the line and is concerned about if the CSX Boston local is routed via the grand junction again pending the sale of pan am; it will basically make freight restricted to track 1 east of Framingham which could cause a bottle neck until the 3rd track is put in.

I am not an expert on they AAR clearance plate classing but I know cars exceeding AAR Plate C must receive Special Clearance from Keolis Engineering department to operate on all tracks between Cove and CP-21. I wonder if this new station with the removed under cut will restrict that clearance plate even more because I know the under cut was really used for the hight of the Intermodal trains going to and from Beacon Park.

The Plate C restriction for the Grand Junction is the Memorial Drive Bridge in Cambridge. I saw a box car put out on the old California Paint Company siding there once because it hit the bridge. Gondolas to Everett are probably the only thing that might go that way but from things I have read, Framingham is getting a bit crowded so maybe not.

CSX will be bringing everything in from the northside which has higher clearances (e.g., Plate F reefers to Chelsea). They stated in their merger documents that they do not plan to bring anything in via the B&A but did not absolutely rule it out just in case.

The vertical height for plate C is 15'6" which just so happens to be the same height the MBTA bi-levels are - found both on a quick internet search. So you won't see anything infringe on that. The Comm Ave bridge over CP-3 is pretty low too.

I've heard from a pretty good source that the undercut on track 2 through Natick Center was excessive and other bridges on the line to the east already had shorter clearances. So they raised track 2 through the new station to try and address the drainage issue but did not reduce clearance to be shorter than what was already the ruling clearance on track 2. In other words no impact to any potential freight operations on track 2.

And as bostontrainguy said Pan Am now has a Plate F cleared route into Everett via the Lowell Line since MBTA took care of the issue near Sullivan Square last year. With most of the Plate C reefers retired nationwide it's really the only option for Chelsea produce.

It appears that there is a relatively good chance (Maybe contingent on the federal Infrastrucure Bill) that the Newton stops get re-built with dual platforms within the next decade.

Those designs look like they have problems, such longer walks for pedestrians, and the pedestrian crossover bridge is higher than the adjacent bridges over the railroad tracks (which will never be raised as they are already as high as possible).
