Are you cool if I move this to the OLT thread?
Everything helps, sure. But the point is you can't hand-wave at what's basically the laboratory example of world perfection for achievable headways in supremely well load-distributed system and claim that can be done anywhere but for wearing "big boy pants" (whatever that's supposed to mean). You could dig up Line 14, airlift it verbatim to Boston with all its personnel and even all its Parisian commuters replacing their dumber Boston counterparts...and in total verbatim state its headways would be a minimum 100% worse (3 minutes not 1:30). Because instead of intersecting HRT transfers at majority of its stations it's now crammed the near-entirety of that distribution into 2 consecutive hyper-concentrated stops. How are you going to close those doors faster?...by stationing soldiers with bayonets to pants-shitting fear people to board faster? Your airlifted replacement Parisian commuters aren't going to fare much better than the Bostonians in that kind of loading situation.I have to think implementing true Spanish Solution pedestrian flow at Park on the Red Line platforms would go a long way to easing dwell time penalties there. Or are Americans simply too clueless to be directionally herded as pedestrians?
Can't help you with DTX or SS.
In Mexico City, which you ignored, closing doors close. If you stand in the way, you get squeezed like an orange. People learn fast that ding ding ding means youre either inside or outside, but not both. The door is stronger than you.How are you going to close those doors faster?...by stationing soldiers with bayonets to pants-shitting fear people to board faster?

A practice such as that which is absolutely 1000% illegal under ADA laws does not a Boston-relevant example make, so nothing was "ignored". Door sensors do have exact accessibility specs they have to follow on their cycling which outright prohibits such draconian measures as "squishing people like an orange" from ever being allowed.In Mexico City, which you ignored, closing doors close.

And since the next train is just 90 seconds away, it's not a big deal. American love to hold doors open because it could be a 12 minute wait if you dont get inside.
Im pretty familiar with ADA law, since its a significant portion of my work, and I dont recall a section mandating that the doors recycle.A practice such as that which is absolutely 1000% illegal under ADA laws does not a Boston-relevant example make.
It's in the accessibility specs guides helpfully hosted on the T website; look it up yourself.Im pretty familiar with ADA law, since its a significant portion of my work, and I dont recall a section mandating that the doors recycle.
I can also give you a laundry list of places where the MBTA has ignored ADA law for 30 years.
This is true even in situations where the cost of following ADA law is zero. IE, when the automated stop anouncements are broken, the driver of the bus/train must make them. Ive yet to find a bus driver that does.
And here we go again with the context-free strawmen. RER A is a 4-branch system that splits/combines on either end in what's considered "Zone 3" of 5 concentric zones and unites through the CBD in an 8-station interlined mainline segment. Quite obviously not an Orange Line analogue in the slightest. The interlined segment has SIX consecutive transfer stations with transfers to TEN different Metro lines, multiple RER lines, SCNF high-speed rail, and multiple suburban lines. The only two stops that don't have other-line transfers...are the branch-transfer stations at the splits. As alien a setup to Orange's State-DTX gravitational singularity, Haymarket-NS, and Back Bay as humanly possible. Again...you could airlift the whole fucking RER A across the Atlantic--better-mannered Parisian passengers at all--to Boston and it would would have TWICE-or-worse the headways right from the get-go because the transfer density is complete opposite-universe more concentrated and exerts an order-of-magnitude more punitive dwell limit on headways. The biggest-boy transpo pants on Planet Earth will not cover over the fact that it only does what it does because it has that extremely many transfers taming dwells over the 100% entirety of its mainline...and nothing in Boston does or ever will.Apparently RER A (Paris), which branches on both sides, and has extremely heavy traffic in the center, runs every 120 seconds, with a goal to reach 108 seconds. Each train carries significantly more people than the orange line. Each new train is set to carry 1725 people.
So clearly, impossible to branch the orange line.
Transfers (“more people getting on and off”) do increase dwell times. But transfer stations doesn't create more transfers as much as they spread out existing transfers.I'm confused as to why transfer stations help with dwell times. I'd think the opposite would be true, as there's more people getting on and off.
Red-Blue is the #1 reliever be flushing double-transferees from the Park and DTX platforms. You have to complement that with the whole bag of egress tricks at those two stations in tandem. Completing Silver Line Phase III or a Green Line-Seaport equivalent is then #2 with a bullet as R-B's positive effects on Red specifically will not be everlasting as growth continues unabated from both the north and the south. After this many decades of delays on both projects we have to consider the relative shovel-readiness of R-B as a five-alarm urgency, because putting Seaport-Back Bay through a full redesign and funding process is going to easily chew all of the ensuing time before R-B relief gets re-topped by new growth. So getting a study re-start on #2 is also five-alarm urgent.F-line - Can you list the top 2-3 changes we would need in order to reduce the singularity at DTX? In JumboBuc's terms - how do we reduce X? Is there is a combination of prerequisites that makes branching Orange feasible?
I assume RBX is one. Does NSRL contribute meaningfully? Urban Ring? and if so, which parts specifically?
