This is definitely true.

I'm still quite new (hired at the end of October, revenue service mid-January) at the job but have plenty of experience riding, albeit I have always preferred riding Orange over Green through downtown if there isn't a major headway gap on the Orange.

I don't have any hard evidence either but as a rider I'll agree that I have noticed an increase in the number of standbys on the Green Line. As both a rider and operator, I am inclined to blame dispatch.

Why dispatch does the things they do, I don't know.... during the last diversion I got held at St. Mary's for 6+ minutes multiple times. Having to explain that one to riders was fun. They also expressed me from Reservoir to Riverside a few days ago but they didn't bother calling me until I was already off the platform at the Res, so they had to make it express from Newton Centre (expressing from Chestnut Hill would have been a violation of policy). This came just minutes after they caught me right as I was opening my doors at Longwood to go express to the Res. I am fully convinced they need an extra dispatcher or two. One time in training we waited over 10 minutes to officially have access to the right-of-way just so my instructor and I could throw the switches at Chestnut Hill Ave going from Cleveland Circle to BC, all while our train was blocking traffic. Obviously the rule is FTA-mandated, but the dispatchers were just ignoring us and letting us sit there even though there was a gap in service on the BC line which would have been a good time to slide right onto the line. They, in my opinion, need more people on light rail dispatch.

As others have mentioned, the signal system is ancient and its ability to have high frequencies is counteracted by its ability to let trains crash. There is a signal coming into Park Street westbound on the D/E platform that stays red even when the platform is empty, then changes after several seconds. There are also a few "time light" signals (the most annoying of which are near Kenmore and Hynes) that serve to slow us down on purpose. They aren't even controlled by OCC or anything, they're just always defaulted to red and only change when the train has been in the current block for long enough (provided the block ahead is clear). They change directly to green, unless a train is close enough to warrant a yellow. These aren't new, but I don't know if the one at Park might have been recently re-programmed to also serve as a time light or if it's just faulty. I have no hard evidence for this whatsoever but I wonder if the signal system has been tweaked since the FTA came in -- it wouldn't surprise me at all.

The Green has always been the line with the longest and most frequent standbys in my anecdotal experience; I've been on trains that have been held on the heavy rail plenty of times but aside from what I refer to the "standby of fate" on the Red Line (11-minute standby at JFK that allowed me to say goodbye to my dying grandfather because the standby made me miss the Orange Line and thus a train at North Station), the only 10+ minute standbys for no obvious reason I have seen have been on the Green.

I should also note rolling stock is an issue on the Green Line. Maybe I already have. I got a bad train for my last trip Tuesday out of Medford, I was driving the 8 in front and the trailing 7 kept springing propulsion faults that dramatically slowed the trip down. I would reset the propulsion at every stop and it would just come back. It was bad enough that I was giving the train full power coming into Govy on the westbound and could only get the train to 5 mi/h (in a 6 so that's okay, but with the master controller to full throttle is not normal), and then coming back (because the officials and dispatch had me keep moving rather than swap me with a train headed to Riverside/Reservoir somewhere) I almost stalled on the incline coming toward Science Park. The train was slowing down, already below 5, again giving it full throttle. Stopped my train, reset the propulsion (which is as simple as clicking a button), and was able to kick it to 12 or 13 before the fault came back but I was able to give myself enough momentum to get up the hill. I then got expressed from Lechmere to Medford/Tufts. Anyway, one train with a particularly bad propulsion fault can mess up the subway (and if said train goes onto Riverside or Medford.... good luck! I've had bad trains like this on Riverside multiple times and it's awful). I feel like the wire car has also been out a lot lately, which tends to goof it up too.

Your insights are incredibly valuable and I really enjoy reading them. Thanks for contributing to this forum. You make it a better place.
 
The habit of the GLX expressing to Medford/Tufts once it’s on the downslope into East Somerville, rather than at Lechmere is annoying. Usually the train has just loaded a bunch of folks waiting on the platform, only to disgorge them one stop later. It seems more efficient to leave them at Lechmere.
And maybe this is just my bias because it's my home station, but I think (at least based on predicted ridership numbers) Gilman Square is the busiest station north of Lechmere (except maybe Medford/Tufts). It feels like it would make more sense to express from there instead of East Somerville.

A couple days ago I was on an absolutely packed train and I overhead our operator arguing with dispatch after they asked us to express from East Somerville to Medford/Tufts. The operator made the argument that unloading a crush loaded train would eliminate most of the time savings from expressing, which was apparently convincing, because we didn't express—and then the train really emptied out at Gilman.

How many possible express routes are there across the entire MBTA system?

I know someone on reddit posted about Harvard to Alewife express trains on the Red Line.

On the Green Line E branch Brigham - Northeastern can be used for express, and it seems East Somerville - Medford is another segment used for express.

Not sure about the B, C, or D branches. Although I'd assume Harvard Ave (B), Coolidge Corner (C), and Riverside and Reservior (D) are used as start or endpoints for express.

Does the Orange and Blue lines never use express trains? Are there any other station pairs on the Red Line used for express?

I have seen Orange do random express runs when the schedule is way out of whack. Like Back Bay to State or even North Station; North Station or State to Back Bay (skipping transfers due to crowding).
 
I have on multiple occassions seen the Orange Line express from Ruggles to Forest Hills. This may be the most common and logical stretch to express the Orange Line to correct headways. I say that as somebody whose home station gets skipped when that happens.

When I lived on the B-Line, it wasn't that uncommon to get express trains between Blanford and Packard's Corner. For Orange Line, I've experienced various express pairings involving Back Bay, Ruggles, Jackson, and Forest Hills.

The rule is we can now only be only expressed between ADA-accessible stations. This doesn't matter that much on the heavy rail with the one inaccessible stop being Bowdoin, which you couldn't express past no matter how much you try (at least till Red-Blue is done then *every* train will express past the current station site, but I digress); however, this matters quite a bit on the Green.

Coolidge Corner and Washington Square, then Washington to Cleveland Circle, are extremely common on the C - they will even often give it as one command "Coolidge to Washington and Washington back". Sometimes you'll see St. Mary's to Coolidge. On the B, a very common one is Harvard Ave to Washington St, then Washington to BC; you also get BU East to Babcock or Harvard a lot, and sometimes they will run express from Kenmore. In the past, as @HenryAlan noted, Blandford to Packard's Corner used to be common from what I've heard too, but with the newer ADA rules they really aren't supposed to do that anymore.

The D and E give you more options with more accessible stations to work with. Brigham to Northeastern is by far the most common on the E, then East Somerville to Medford. The D is all over the place, but they will basically always stop at Reservoir and most of the time they stop at Woodland; besides that, there are many possible combinations that are used on the D.

Occasionally, they will also express on the inbound -- I got expressed from Riverside to Newton Highlands on Monday.

I've seen Ruggles to Forest Hills trips go express on the Orange, though it isn't common these days as they still are not quite back at pre-covid service levels.

I can't say I've ever heard of it happening on the Blue Line, I'd be interested to know if it's ever happened and what stations they'd even skip -- if it's ever happened, Orient Heights to Wonderland would by far make the most sense.

Right, I should have mentioned that I haven't been a regular B-Line rider in more than 25 years. I don't think there were any ADA compliant surface stations in those days.

The T's response on the slower than expected green line is essentially that it's old and will likely always be slow, but now it's safe.

Nothing wrong with the safe part, but they were advertising 9 minutes of saved trip time with the removal of these slow zones, and they've been very public in the past about saved trip time...

 
So they have made it safe and potentially faster, depending on equipment, dispatch, and other circumstances. So there may be some trains that traverse the route in 9 minutes less time here and there, just not something we should expect as a regular performance. I agree that more communications clarity up front would have been good, but overall, I can accept this result. GLT is happening, and in the mean time, it should at least be more reliable.

Which subsection of GLT projects is going to decrease travel time?

Not an explicit goal in GLT, but:
  • Bigger vehicles (two-car Type 10s) improving capacity, thus reducing dwell times
  • More reliable vehicles reducing breakdown rates
  • Signal upgrades and train protection system upgrades, which may possible resolve some of the ridiculousness in the present-day signal system (though that part I'm less certain about)
 
I almost stalled on the incline coming toward Science Park.
First of all, thank you so much for the insights.

I have a long-standing question about this part. As I mentioned here, a Reddit comment claimed that between Science Park and North Station, signals are set up such that in both directions, if two trains are close together, the succeeding train cannot enter the steep incline between Science Park's platform and at least the turnback (if not North Station's platforms) until the preceding train has cleared the entire section. This poses a capacity limit on the section and GLX.

Is this true? If yes, do you have any idea whether this is a safety precaution, or just drawbacks of the signal system (that can possibly be improved in the future)?

Will GLPTS bring more lenient operating rules (for example, allowing two trains to berth on the same platform again) or will it be so strict as to slow the whole thing down even more?

As a D branch rider, by far the most common express I see is Reservoir to Longwood; especially pre-COVID, it would happen nearly every morning. I also see Newton Centre to Woodland sometimes, but not nearly as often.

That is true, the signal protection in the Turnback area is set up that a train at Science Park cannot leave until the train in front of it is, I believe, at the curve right before the North Station platforms. I forget what the signal bounds are headed toward Science Park but I know it's something similar. I think I have a diagram somewhere.

My understanding is it's by design (presumably as a safety protection for the North Station Turnback) and is not a drawback of the signal system. The slow speed of the turnback area has always driven me mad given how close by Science Park is to North Station.

Anecdotally, I hear Longwood to Reservoir the most on the radio. Happens all the time. That said, they sometimes come up with interesting combinations: one time I was on a train that got short-turned at Reservoir after being expressed from Fenway.

Will GLPTS bring more lenient operating rules (for example, allowing two trains to berth on the same platform again) or will it be so strict as to slow the whole thing down even more?
This I'm not sure about. I hope I'm out of the seat and in some desk job at the T by the time GLTPS is implemented, just as a general career goal (hoping to go back to school in support of that goal), but if I am in the seat long enough to still be driving when GLTPS is done, I will be interested to see how it works in practice.

That's good to know that another operator actually pushed back successfully on dispatch nonsense. I had a bad train this morning that kept braking randomly and jerking, kinda going into a "slow emergency" repeatedly. I called it in and their response was to...... send me express. The Cleveland Circle official was mystified that they didn't say anything else.

same, when I lived in Allston a few years ago it was very common for the B to express between Harvard and Blandford, much to the chagrin of the people waiting at Packards Corner to go inbound
 
The Ashmont Branch, which had a 2 week shutdown to fix all of the slowzones on the branch barely over 3 months ago, already has speed restrictions once again.

Looks like the shutdown didn't fix everything. If the tracks can't go more than 3 months without new speed restrictions, seems problematic to have speed restrictions this early and this soon after shutdowns lasting half a month?
