GTFS for Spring 2025 is now out:
MBTA GTFS data is now out for Summer 2025 up to August 23rd, 2025, although PDFs and the list of changes are not available yet.
This summer,
Weekday service decreases on the
Green Line and increases on the
Orange Line.
Saturday service will
decrease across the
MBTA bus system, but the bus network will have a very small Sunday service increase.
Overall, net scheduled trips on the MBTA bus and subway system will decrease this summer, largely driven by reduced weekday Green Line service and reduced Saturday bus service. This does not include the reduced Fairmount Line service every day as part of the Summer 2025 service changes, which would mean systemwide service levels decrease every day of the week across the MBTA this summer.
(The scheduled revenue bus service hours update for Summer 2025 I won't be able to do until late July)
Here are the service changes for Summer 2025:
*
Orange Line weekday frequency
increases from every 6 to 7 minutes to every 6 minutes
*
Green Line E Branch weekday frequency
decreases from every 7 to 8 minutes to every 8 minutes
*
Green Line B, C, and D Branches weekday frequency
decreases from every 8 minutes to every 8 to 9 minutes
*
Reduced service every day on the Fairmount Line and the 55 bus
*
Reduced Saturday service on the 8, 9, 11, and 504 buses
*
Reduced Sunday service on the 24 bus.
*
Reduced Saturday and Sunday service and
increased weekday service on the 10, 712, and 713 buses
*
Reduced Saturday service and
increased weekday service on the 716 bus.
*
Reduced weekday service and
increased Saturday service on the 106 and 108 buses
*
Increased weekday service on the 95, 116, and 430 buses.
*
Increased Saturday service on the 90 bus.
*
Increased Sunday service on the 34 and 201 buses.
*
Increased weekday and Saturday service on the 96 bus.
*
Increased Saturday and Sunday service on the 110 bus.
Overall, 18 routes see reduced service and 18 routes see increased service. On the bus network, 14 bus routes see more service and 12 bus routes see reduced service.
I've also updated the MBTA frequency map again with the following changes:
*
Downgraded the Fairmount Line from "Every 30 - 60 minutes" to "Every 2 hours or worse", due to the Sunday trip count dropping below 21 and 11 trips (26 → 9)
*
Upgraded the 201 from "Every 1 - 2 hours" to "Every 30 - 60 minutes", due to the Sunday trip count exceeding 21 trips (18 → 28)
*
Upgraded the 110 from "Every 15 - 20 minutes" to "Every 12 to 15 minutes", due to the Sunday trip count exceeding 81 trips (80 → 81)

I know
@Teban54 has a dedicated "transit data analysis" thread, but I'm relunctant to post these updates there; unless all my linked older posts above can also move to the new thread. I prefer these MBTA frequency updates to all be in a single thread.
