Yes, like you, I've been following the transition from the start, and it is great to see. The other thing that excites me about how close it has become to the original concept, is that it can now start to also serve as a model for transforming some of the other lines that run through EJ communities. We should be able to achieve something similar for the inner Newburyport/Rockport line, for example. And since it clearly works to increase ridership, why wait?

Well.. the issue with South Station at least was the lack of space there. I guess this means they have no plans on bringing back full peak service on the other SS lines. I believe the crunch at NS is less of an issue.
 
Aside from the Lechmere Viaduct, which is a very strange case of moving the goalposts, I know that the primary reason for the lowering of speeds for the Riverside Line (and thus the GLX mainline) is the Type 8s. Their poorly-designed center trucks have a bad habit of derailing above 40 mph, and it takes extra rail grinding to keep that from happening. When I was doing my research, one of the higher-ups in track maintenance told me it'd be cheaper to maintain tracks to 50 mph for Type 10s [assuming they don't have truck issues] than they currently spent maintaining to 40 mph for Type 8s. While I'm cynical it will actually happen, it's not unreasonable to hope that some speeds can be increased once the Type 8s are retired.

With 30min being the scheduled run time of the Fairmount under diesel power I'd assume they'd run 2 dedicated trainsets all day that only dwell at the ends long enough for boarding and alighting (and if they're ahead of schedule). Compared to currently where they sit at the ends for ~15min, this would probably free up a slot for a quick turnaround of another train.

The reconfiguration of Tower 1 interlocking at South Station is under way - the main construction contract was awarded last year. That should streamline movements through the "throat" and increase capacity a bit. Additionally, as Koopzilla pointed out, dwell times shouldn't be terribly different, so the platform utilization won't be that different that current.

Also, if some of the increased Fairmount service is Franklin/Foxboro trains diverted from the NEC, then that's both fewer trains coming from the NEC at South Station, and fewer crossover moves north of Readville that limit NEC traffic.

Much more likely that they're running 3 trainsets at all times (+1 trainset on weekdays and +2 on the weekend). Leaving literally 0 time for dwells or schedule recovery would be a recipe for disaster. Ops can and should be improved, but we can't rely on literally perfect schedule adherence. As a frequent Fairmount rider I would be extremely worried if shorter dwells was their sole plan for 30 minute service.

The April 25 2024 edition of the Track Improvement slides is already comically outdated.

1. The Lechmere slow zones were fixed ages ago
2. The Cleveland Circle fall 2024 diversion was cancelled since they did it in the winter shutdowns.
3. The Blue Line diversion at Wonderland is a single diversion, yet it is displayed as 2 diversions (The Bowdoin diversion is a separate diversion that was done as early access)
4. The Orange Line shutdown for June is in the first week of the month, starting after Memorial Day, and it extends to Wellington, not Sullivan.
5. The March diversion of the Orange line started at North Station, not Haymarket.

These changes were made over a month before today's MBTA board meeting. https://cdn.mbta.com/sites/default/files/2024-04/7. f. TIP Update Full Board 04.25.2024b.pdf

I think the answer here is that the Track Improvement Program isn't only about slow zones, they're trying to get all the parts of the track up to a better state of repair. So, Items 1 and 2 would still remain because there's still much needed work for sleepers, ballast tamping, rail replacements that are not causing slow zones, but, are maintenance needs.

Yeah, the 40 mi/h cap on Green being due to the 8's is well-documented. The other cases of moving the goalposts, both on the Green and on the heavy rail, are curious.

This is exactly what more people need to understand. The Green Line is (for the most part) just a tram and incredibly subject to human variables in speed and schedule adherence. Entire long light cycles at major intersections can be missed when an operator decides to kindly reopen doors for passengers arriving after they've closed setting them back minutes. There's also differences in levels of caution taken around pedestrians and cars crossing tracks depending on how experienced or confident operators are with stopping in time for sudden events

Also this -- I get being nice and I try to be nice, but ultimately, if that light is green, I can't always wait, no matter how hard you are running or whether you knock on my door or not. One time I missed a light cycle due to crowding, and then missed another light cycle because the person in back decided to pop their door back open for a runner right as I was starting to move. It's nothing personal (at least not for me) -- many other people are affected sometimes when a door is reopened like that. Many of us know the light cycles well enough to judge whether reopening a door is feasible or not, but many do not. That just comes with experience.
 
If only we had something that could prioritize the train at lights or something crazy like that....

Also, could you imagine at rush "hour" on the 93 parking lot seeing red line trains zipping by at 55-60 mph every 3-4 minutes? Ridership would sky rocket, can't buy advertising that perfect.

This us in the technical requirements for the Red #4 and Orange #14 rolling stock so with the new digital signaling the capability is there to make it safely happen when track work is done and fixed. Full depth track replacement of various parts of the rapid transit system is in the CIP so if its not rebuilt to a 55+ mph standard this year it may be by the time we get all the CRRC Red Line cars delivered
 
According to MBTA Twitter they opened service with a signal issue that caused delays on the Blue Line...hopefully by end of day we'll be able to actually see better service and elimination of slow zones on Transit Matters. Then onto the Red Line starting tomorrow...
 
More on the Blue Line. They are very much doubling down on the "NO MORE SLOW ZONES" message. Let's see if it holds. Admittedly, looks like a lot got accomplished.

With unencumbered access to Blue Line stations, crews were [sic] accomplished the following work:

  • Replaced 22,500 feet of rail.
  • Replaced over 9,000 feet of overhead catenary wire.
  • Replaced more than 10,000 ties.
  • Installed 48 composite ties at trip stops.
  • Approximately 41,000 feet of track was surfaced and tamped.
  • Replaced approximately 1,000 feet of full depth track.
  • Replaced approximately 700 feet of restraining rail.
  • Installed approximately 35 switch timbers.
  • Repaired stairways at Wonderland, Orient Heights, and Wood Island.
  • Performed station inspections and standpipe testing.
  • Repaired the operator’s platform within the non-passenger area on Wonderland and operator’s walkway at Orient Heights.
  • Replaced approximately 500 feet of fencing between Beachmont and Revere Beach.
  • Repaired roof canopies at Wood Island, Orient Heights, and Suffolk Downs.

Whether they'll actually use that 55+ mi/h spec or not is a whole different ballgame
 
Planning is underway for a new dedicated transitway for the E branch – which could be shared by the 66 and 39 buses as well.

The project needs to be done by 2027 for the new Type 10 trains:

There's the online public meeting as well so hopefully there will be more details shared then.
 
Highlights from the Huntington Ave Meeting:
  • Median vs Side running has not yet been determined
  • Transit lanes will be designed for trains and buses wherever possible
  • Platforms will be 225ft to accomodate double type-10s.
  • Design process to be largely completed by 2024
  • Stated beginning of construction was set at 2027 though? Super unclear.
  • Hyde Sq will not happen until after this project is complete, but the design will not preclude such an extension
  • Stop consolidation is on the table, but will be weighed against the needs of local senior centers and the VA.
  • Back of the Hill is almost certainly getting the axe, the grade is too steep for platforms.
  • There is a type-10 mockup coming, it is currently in production
Questions and comments:
  • Lots of concerns about the Huntington/South Huntington intersection
  • Questions about TSP on the 66 going into Brookline
  • Will outdoor dining at Brigham Circle be affected (A: The goal is no)
  • One guy really annoyed at the Hilton using River Rd for dining
  • Will the type 10s squeal?
  • Some disbelief and skepticism that the type 10s will actually fit through Boylston
  • Lots of other questions about the type 10s in general.
