Waverley station
While Belmont station is on a viaduct, Waverley station (also in the town of Belmont) is in an open cut. Waverley looks to be in very poor condition. There's little parking here, but lots of bus (and trolleybus) service; with some investment and fare integration, it could be a useful transfer station for travelers whose destinations are in Boston rather than Cambridge.

I guess they tried to hide the disintegrating concrete by covering it with paint, but it's clearly not working on the outbound stairs. The sign is a bit of an oddity, because there's no crossing provided at platform level; I'm somewhat surprised that there's no fence between the tracks here.

Looking down the whole length of the station from the west end of the outbound platform. Of course it's both below standard length and low-level, although there's plenty of room in the right of way to fix both. (The T will refuse to fix either of these because they would be required to install elevators if they made any substantial modification to the station, and they're very bad at elevators.)

OK, I did actually dash across the tracks despite there not being a proper grade crossing, just to get a better look at the spalling concrete on the wall below the stairs. The retaining wall proper seems to be on acceptable condition, so it must be an issue with water management on the stairs.
Former site of Beaver Brook station
Immediately south of US 20 (Main St.) in Waltham, the line narrows to a single track for about a mile. Waltham Lumber on Massasoit St. stores some of their inventory on the site of the former Beaver Brook station, which was closed early on in the MBTA era. The yellow stripe is all that's left of the former platform, which last saw passengers in 1978.

On the other side of US 20, there is Petco and a CVS sharing a huge parking lot, and across Route 60 is Waltham District Court and a dense residential neighborhood. In a Regional Rail model, this would be a priority station to restore, because it could both serve local residents and businesses, and relieve the #70 bus, which is the primary transit service provided to Waltham and western Watertown. There's plenty of room in the right-of-way to support a two-track, high-platform station with ramps up to this parking lot and elevators to US 20 for bus connections.

Now on to one o the weirdest stations on the line, Waltham. We're looking at the city parking lot right now, which is closed for some reason, towards the extremely substandard inbound platform. The single-track section ends just west of Moody Street, which is behind me, and the outbound platform is located on the (mainly) double-track right of way.

At the east end of the station there are, unusually, a couple of bus shelters on the platform. While most low-level stations do have shelters, they are typically much larger; these are very obviously the same shelters as are used on bus routes elsewhere in the system. The service change notice over the trash barrel explains that this line is being bustituted until May.

Looking west from Elm St. back toward the Moody St. grade crossing. There's clearly enough room for two tracks here; in fact, Google Maps thinks there still are two tracks here. Why isn't this a two-track station? Perhaps it's because the whole block simply isn't long enough: it's barely 500 feet long, and MBTA trains can be up to 800 feet long, so a proper station here would block both Moody and Elm for stops in both directions. (two 75m FLIRTs would just barely fit, but would occupy the track circuit and keep the gates down for the full dwell time.)

See those little white square signs? They tell the engineer where to stop based on the number of coaches in the train. They go up to 7, which means that at least two coaches of a crowded rush-hour train won't platform here. I do not understand why they did this when there's plenty of room for a full-length platform.
Kendal Green station
After COVID-19 related service cuts, Kendal Green is the only station in the town of Weston still open, in large part because it's the only one with meaningful parking and therefore ridership. The commuter parking here is town-owned and runs along the road at left, which leads to a landscaping supplier and the town transfer station. About 500 feet beyond the signal is a bridge where the former Central Massachusetts RR crossed the Fitchburg; it's now the Mass Central Rail Trail.
