Or how about... real afterburners?
Why fake? Didn’t your spin-out link also include a fire-belching exhaust stack?
Real afterburners in dinosaur/plant-juice-less electric motors usually result in reduced lifespan.
Indeed.. I misread that this was for utopialectriclocos.

I can't help noticing those vacuum motors sound a bit like a DC9.

I love it when I discuss a product with relatives either by chat, phone or in person (but in presence of an El Teléfono Inteligente or similar ungodly device) and then we (Not_italics) start getting ads for said product. It's a conspiracy and I blame Elon X, Tim Apple, Bill Microsoft, Mark Facebook and Sundar Google.

For what it's worth, i found another group of people that don't seem too enamored with the braking ability of a train: https://www.youtube.com/watch?v=JUKPn73I5hk

All you engineers do is complain.

What suggestions, albethem outsider suggestions, do you have to improve train braking?

Do they know that cars have had disc brakes for about half a century?

I haven’t studied disc brakes on US passenger trains (they exist and work smoothly based on some train rides). But I suspect they are better than the crazy levers and rods and chains and God knows what else that transfers the pressure from a couple brake cylinders under the car through the trucks to eight brake shoes…

I find it reminiscent of MCAS, DC-9 ailerons, and Lockheed Electra APUs.

Fixed.

From Wikipedia:
Successful application began on railroad streamliner passenger trains, airplanes, and tanks before and during World War II. In the US, the Budd Company introduced disc brakes on the General Pershing Zephyr for the Burlington Railroad in 1938. By the early 1950s, disc brakes were regularly applied to new passenger rolling stock.
Even we (Not_italics) have disc brakes in our new Chinese trainies (embedded in the wheels in EMUs, inboard in locomotive-hauled cars). I believe our semi-vintage (1982) Japanese EMUs also have disc brakes.

You know, I DO care about train braking, but maybe I’m more interested in making sure they work, versus improving their nominal performance.

Si.

y hay otros zoológicos que han tenido accidentes de trenes. Prohibir todos los trenes del zoológico.

To expand a bit on your teeny text I have 2 words: SUBWAY TRAINS.

Unlike freight trains, they're already electric. And also unlike freight trains, they spend a very large portion of their operational time accelerating and decelerating (or accelerating toward the rear if you're a physics major). And they always have an "alternate power source" available if the battery is in a mood. The ability to travel to a nearby station under battery power if line power is lost would be another big plus.

Why no work seemingly is being done in this area completely baffles me. :?
I have a vague recollection that the new Red Line trains that came in in the 90s had some amount of regenerative braking.
