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.
It's in the accessibility specs guides helpfully hosted on the T website; look it up yourself.
Non-compliance with ADA is non-compliance is non-compliance. That there are examples of non-compliance in our backyard does not mean the barn door is legally open to nullification and anything goes. That is no counterpoint. You claim to be familiar with ADA law, so this should not be news to you in the slightest. It is illegal...illegal illegal illegal...to program vehicle doors to close with excessive force on a person moving slowly through the vehicle entrance. Conditioned behavior of patrons on the platform has nothing to do with that, nor do people holding the door with due or undue courtesy. You can not speed a door queue by enforcing a physical-strength penalty on patrons, and it does not matter AT ALL if that works 'totes awesome in Mexico City. It's illegal.
Filter out the examples that are blatantly illegal or physically impermissible here before posting. Those examples have zero relevance to showing a way this system could do things better.
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.
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.
This is not hard to filter. World comparisons aren't relevant when they can't be physically and legally implemented here at the most basic of levels. Pick way better strawmen than this if you insist on continuing to beat this horse over and over.
