'We know this morning was frustrating for many': Reopened Blue Line hobbled by signal problems

The transit agency said it would not collect fares on the Blue Line or the East Boston ferry on Monday after signal problems snarled service.

Just before 6 a.m. on Monday, the MBTA said shuttle buses were continuing to replace service between Government Center and the Airport to allow the completion of overnight track and signal work. By around 7:30 a.m., the agency said regular service was being resumed and shuttle buses were being “phased out.”

But then around 8:15 a.m., the MBTA reported a 30-minute delay due to a signal problem, announcing just before 11 a.m. that shuttle service would again replace train service due to “multiple signal issues at Maverick.”
[...]
Around 4 p.m., the transit agency said regular service had resumed, but warned that riders could experience “longer wait times and delays throughout the day due to an ongoing signal problem near Maverick.”

Mass. lawmakers reach deal to seed MBTA with $535 million from ‘millionaires’ surtax spending package - The Boston Globe

The package unveiled Monday splits the difference on MBTA funding proposed in bills in the House and Senate, and includes $300 million alone to replenish the MBTA’s budget reserve.
www.bostonglobe.com www.bostonglobe.com
The surtax spending bill the Senate passed last month would have dedicated $370 million to the MBTA, including $200 million to replenish the agency’s budget reserve. The House, on other hand, sought far more, setting aside nearly $800 million for the T, most of which — $700 million — was tabbed for the agency’s reserve and deficiency funds.

The bill released Monday falls in the middle. It would dedicate $300 million for the T’s spending reserve, plus offer $175 million for workforce and safety funding. Another $40 million would go toward infrastructure upgrades, and $20 million would help fund the MBTA’s low-income fare program.

I was riding with my friend on Blue (he commutes on it) and noticed that the train announcements were 1 station off. I asked and he said it's normal. Anyone know about this?

I occasionally commute on the Blue Line and have never noticed that. But as it's occasional, it's possible that I just haven't paid enough attention. I should add, though, that I've noticed such issues now and then on all automated station announcements.

I notice this sometimes on basically any train, and not just Boston. Just a coincidence, but I've heard this problem a bunch, maybe 4-5 times, in the past couple of weeks. All on Red or Green trains.

I'd actually be curious how those systems work, and if they work better on the new CRRC trains. I don't ride Orange much these days, but I've never seen this problem there.

Red Line's announcements being one stop off, particularly on the 1800s, is quite common.

I take the Orange Line 2x daily during the week and I feel like I've observed the issue in question happen exactly once since the CRRC fleet replaced the old.

I have noticed the announcement problem on the Blue Line. Train operators often come on the PA to correct the announcement.

It works the same way on all 4 lines. The cars ping RFID tags placed on the ROW coded with the station ID's, because GPS doesn't work well in the tunnels. Missed signals can cause hiccups in the system requiring the operator to manually intervene on the onboard computer to reset the station sequence, and that's particularly a problem with the Red 01800's.

There is something really weird about the "unique coding" versus a "sequence of announcements". If the system really used unique coding mapped to unique messages, it would be self correcting (miss an RFID read, simple skip the announcement, and move on at the next RFID site to the correct message). Clearly the trigger is for next message in sequence, rather than for a unique message, so once a sequence step is missed, the system is fubar. Not a very robust design.

To be fair, what you describe is the intended function of the system as per the 2013 specs which the CRRC cars are supposed to adhere to. Any issues therefore on the CRRC fleet is indeed odd.

However, given that the same spec provides that the winning bidder is to provide new tags, its entirely possible that whatever encoding they've provided confuses the ca1990 electronics of the 1800s, which perhaps default to the "known station sequence".
The AASCS on the lead car shall read the transponder code provided by the ASI tag reader and look up the appropriate pre-recorded audio and text announcement to be broadcast at each station.
E. When the train passes over the transponder at the entrance to a station, the AASCS shall control the PA system and Announcement Signs to make voice and text announcements of:
1. The station name
2. The side(s) upon which doors will open
3. Connection information
4. Relevant information about the station such as elevators out of service etc.

Just speculating, but I wonder if station-sequence is used a fallback behavior. e.g., "We passed a transponder but could not read its signal, so we will assume it is our last known position + 1."

You can imagine, then, how a semi-operational reader on a train would have an off-by-N problem if it knew it was passing transponders, but couldn't read them, and also missed N transponders entirely.

MBTA to borrow $939 million as deficit looms - The Boston Globe

Stories you may have missed from the world of business.
www.bostonglobe.com www.bostonglobe.com
The Massachusetts Bay Transportation Authority is borrowing to help fund transit upgrades. The MBTA plans to sell about $939 million in municipal bonds, according to preliminary bond documents. It is the latest US transit operator to shore up funds as COVID-19 aid from the federal government evaporates and ridership levels struggle to return to pre-pandemic levels. The agency’s deficit is projected to balloon to nearly $500 million by fiscal 2028, according to pro forma forecasts shared in February. It also needs at least an estimated $2.5 billion annually to address a backlog of repairs. Proceeds raised in the sale of the bonds will fund, in part, the modernization of Massachusetts’ subway fleets, the installation of new fare payment machines, and an expansion of its commuter rail fleet with new bi-level cars, according to the documents. — BLOOMBERG NEWS
