D branch service was suspended for over 6 hours because of a disabled train. Was this a derailment??
Sounds like a downed wire.D branch service was suspended for over 6 hours because of a disabled train. Was this a derailment??
I've always assumed that an OLX+1 to Rozzie would eliminate the CR station that is currently there.Also, how are the going to cram 2+ platforms at Roslindale with an OLX? They proposed it in Focus40, so there is clearly some way, but I. just don’t see it. I also don’t see a way to fit 4 tracks through most of that section, unless they will single track the Needham line.
I always assumed the platforms would be staggered. For example, if you shift the Commuter Rail platform 300 ft west (over the bridge), then the CR and Orange Line platforms could be on opposite sides of the location of the current pedestrian underpass.I've always assumed that an OLX+1 to Rozzie would eliminate the CR station that is currently there.
I agree that would work if the goal were to have both CR and OL, but it just never occurred to me that the Needham Line station would be preserved or reconfigured. I guess the question is whether enough riders would prefer transferring to Orange at Roslindale (or just deboarding to do things in the Square). If it seems likely that the numbers would be there, it might be worth the expense of building a staggered multi-modal station, which I guess is the sort of thing the study would answer.I always assumed the platforms would be staggered.

Don't Needham Line riders still have the option to transfer to OL at Forest Hills and Ruggles?I agree that would work if the goal were to have both CR and OL, but it just never occurred to me that the Needham Line station would be preserved or reconfigured.

As promised, the results for the bus service hours metric for Spring 2025:(Stay tuned for the Spring 2025 update to the bus service hours metric in late May 2025, as for that, I would have to access to the historical delivered MBTA bus timepoints file for April 2025, which will not come out for another 2 months).

The systemwide percentages would make some sense to me when i think about my commutes into Cambridge from Medford. However, I don't think Medford sees more weekend service than prepandemic, now. I think my new city is maybe getting the shaft for the whole current bus service regime.As promised, the results for the bus service hours metric for Spring 2025:
I poured through the MBTA's "April 2025 bus arrival departure times" file, and extrated scheduled trips from Friday April 25th through Sunday April 27th (skipping any holiday weekends, and going with school vacation week so I can compare it with the school vacation week during Christmas 2019 pre-COVID).
Weekday scheduled bus service hours seems to be around 93% of pre-COVID hours, comparing scheduled service hours form Friday, April 25th, 2025 with Friday, December 27th, 2019.
Saturday scheduled bus service hours is somehow at 104% of pre-COVID hours (comparing Saturday April 26th, 2025 with Saturday, December 28th, 2019)
Sunday scheduled bus service hours is currently 118% of pre-COVID hours (Sunday April 27th, 2025 vs. Sunday, December 29th, 2019)
The discrepency seems to be there is 8-10% less scheduled trips, compared to scheduled hours, across the weekday, Saturday, and Sunday bus schedules, putting the MBTA's scheduled bus service hours at 95.7% of pre-COVID levels for the whole 7 day week, whereas the scheduled bus trips across the entire 7 day week is only ay 88.2%. The weekday situation is pretty bad (85.8% scheduled trips vs. 93.1% scheduled hours).
The MBTA is short of 1680-ish scheduled revenue service hours from reaching pre-COVID levels (does not include deadhead, non-revenue service hours).
I do not currently have extra bandwidth to do any additional testing or validation, but within what I can do for now, is the results I was able to extract from the data.

The entire corridor from Somerville, Medford, Charlestown, and Malden are the ones with the most service reductions. Everything from the 8x’s, 9x’s, and the 10x’s have reduced service pretty much every day.The systemwide percentages would make some sense to me when i think about my commutes into Cambridge from Medford.

Have you accounted for GLX in your analysis?The entire corridor from Somerville, Medford, Charlestown, and Malden are the ones with the most service reductions. Everything from the 8x’s, 9x’s, and the 10x’s have reduced service pretty much every day.
Oh come on, the COVID and operator induced bus service cuts are mostly still in place still to this day.Have you accounted for GLX in your analysis?
Many of the routes you mention as having the most service reductions are those whose service has been duplicated by GLX. Those should be the routes with the most reduction, logically, as replacing bus service with Green Line service is actually a service gain, not a service reduction.
Also, if your only metric is number of trips, a two seat bus <> Green Line trip would register in your assessment as preferential to a one seat Green Line ride, even though the reality is the opposite. How are you handling those instances, which specifically affect the 8x’s, 9x’s, and the 10x’s you call out as having the most service reductions.
How have you accounted for that?
Malden and Charlestown shouldn't really be seeing service decreases due to GLX, nor should my part of Medford. If anything we should be seeing different routes, reroutes, or new routes but the BNRD doesn't even give us that as a hope in the next 4 or so years.Have you accounted for GLX in your analysis?

Oh I absolutely agree. But Somerville should have seen a decrease in bus service and I want to learn about @Delvin4519 ’s methodology and if they have accounted for this major flaw in their methodology.Malden and Charlestown shouldn't really be seeing service decreases due to GLX, nor should my part of Medford. If anything we should be seeing different routes, reroutes, or new routes but the BNRD doesn't even give us that as a hope in the next 4 or so years.
Again with the advocacy for less bus service?but @Delvin4519 ’s methodology would count that as a transit loss. When you have major reroutes and extensions of frequent routes, like in Phase 1 of BNRD or extension of light rail services, a sound analysis would ensure that it is accounting for these realities.
Let’s elevate this discussion a bit.Again with the advocacy for less bus service?
The MBTA should be running the same number of revenue bus service hours after a rail transit extension as before. The MBTA should have just redeployed the buses onto neighboring routes that are underserved, and still run the same service levels. Like I said, if you rerouted the 87 from Lechmere to Central you would still need the same number of buses to run the route, as otherwise you would just cut service and reduce frequency if you don't keep the service levels intact when rerouting the route to a different terminal.
As such cutting service in the wake of GLX, without doing service increases on neighboring routes, should correctly be shown as a penalty.
Also note that my metrics have 1 specific metric for "excluding discontinued routes". If a route is discontinued (like in BNRD), it is removed from the calculation and the calcuation only uses routes that exist today.
I've iterated in my post that Somerville should have seen service increases with various underserved destination pairs: Union <-> Central, Union <-> Davis, Malden <-> Davis via Medford, Assembly <-> Gilman; etc. Not a service cut.
The reverse is also true for the 86. The 86 was cut in half and so by that metric, it only needs half the service to run the same number of trips. Even the TransitMatters COVID recovery dashboard data isn't able to compare apples to apples. The ridership numbers for the BNRD routes are essentially meaningless when you try to compare pre and post BNRD using TransitMatter's data.Let’s elevate this discussion a bit.
Let’s look at the 109* as an example. The 109 used to operate 50 round trips per day and now operates 100. By your methodology, that would be counted as a 100% increase in service. The problem is, the round trips now are not the same as the round trips then. The 109 has been extended, meaning your methodology undercounts the actual service improvement to this corridor.
Now let’s consider revenue miles. The 109 used to be 9.2 miles per round trip and is now 14.2 miles. That’s an increase from 460 to 1,420 revenue miles per day, a 209% increase in service. This reflects a far more accurate picture of the actual investment and coverage increase than a simple trip count.
The only thing I’m advocating for is better data analysis. Why aren’t you on board with improving methodology, when the flaws are pointed out? You aren’t your methodology and this isn’t a personal attack.
*My data may not match the exact data set you’re using (I’m using 2018 figures), but the numbers illustrate the concept clearly for anyone seeking to analyze the most accurate and representative metrics.
Even for your intended purpose of measuring frequency, the trip count metric doesn’t hold up when routes are restructured. It fails to reflect actual frequency or coverage for riders in corridors where service has shifted. In the case of the 86 and 109, the 86 went from 57 to 65 round trips per day, and the 109 went from 50 to 100. Your metric shows a 54% increase in service across the two routes. But a large portion of the old 86, particularly between Harvard and Sullivan, is now served by the much more frequent 109. Your metric treats those as separate changes, but for riders in that corridor, service has clearly improved in a way that trip count misses.The reverse is also true for the 86. The 86 was cut in half and so by that metric, it only needs half the service to run the same number of trips. Even the TransitMatters COVID recovery dashboard data isn't able to compare apples to apples. The ridership numbers for the BNRD routes are essentially meaningless when you try to compare pre and post BNRD using TransitMatter's data.
With that being said, if TransitMatters is able to come up with a way to compare apples to apples, I would be happy to hear their solution and what they did.
Each metric has it's use cases with pros and cons.
The "number of trips" metric is primarily useful in measuring specific routes and whether they have frequency increases or decreases. The MBTA generally does not do drastic or complete overhauls to bus routes that often, and so most of the time, it is able to be used for most schedule changes. It is also the fastest metric that I can update at this time, and so when a new schedule is announced and posted, that metric is the first to update before the new rating goes live. The metric is also useful in that if a route has more traffic requiring it to run less service, then this metric will show that accordingly.
The "scheduled revenue service hours" is more resiliant to bus route overhauls, and as such, is very useful in that regard. The biggest downside is that this metric is much slower for me to update, and so there is a 6 - 10 week delay in this metric updating to reflect the latest ongoing bus schedule. (It's also just more cumbersome to get this data as well). The other downside is that this metric fails to show bus routes getting slower due to traffic and requiring fewer trips and frequency in light of traffic getting worse. As such, this metric can't show that.
As such, it is best to have both metrics around and understanding their use cases and limitations. I suppose the other useful metric (which I don't have the bandwidth currently to analyze) is scheduled revenue service kilometers/miles, which that data is much much more harder to analyze. Though it would do well in capturing both service levels, number of trips, traffic congestion, and is resiliant to bus route overhauls.
In the case of the 109, if a route had 50 trips before and now runs 100, then it is correct that the frequency only doubled. The frequency did not triple even if you run triple the revenue service hours. You're only waiting half the headway instead of 1/3rd of the headway. A longer route takes longer to cycle and so if you want the same frequency, you do need more service hours to make up the extra difference. So a bus running every 30 minutes pre-BNRD is only running every 15 now, not every 10, because the route length was doubled.
