Haven't seen or heard of anyone adopting this technology since its announcement in 2018.
Never too old to have a happy childhood!

York1 Another big issue -- cost. How much would a railroad pay for one of these cars to use for several miles? How many years would it take the cost of one of these cars to break even with a readily available semi? Edit -- another thought. With all the news about the train robberies, how vulnerable would these autonomous cars be? One of these parked on an industrial siding for several nights somewhere would seem to be attractive to a thief looking for certain metals, batteries, and computer systems.

First off, let's laugh at the idea that the railroad would be buying these cars in the first place.
They would be leasing companies or bought by the industries they serve
Second, from a theft perspective, the relative added theft opportunity could be offset by the same types of things that keep thieves away from your car.
Plus, how many sidings are out in the open not hemmed in by a fence.
That fence would seem to be the bigger challenge to automation. Not insurmountable by any means, but the kind of nuts and bolts issue that is oft forgotten about.
Greyhounds: "to prison?" Hardly. If the conferences are recorded, reported to the STB, and deal strictly with new interline business development. Is there an intermodal lane now Texas - Oregon and Washington? Florida - Michgan? Should not these exist?
Overmod: Hardly inexpensive.
And not only double-track, but also grade-separated.
But I do see a considerable nich market for autonimous freightcars in intra-plant railroads with multiple origine and destination points..
I can see these running in a sort of conveyor system, on a closed system. Instead of assembling a train of x cars, just load each car and send it on it's way. If the ROW is double track, great, otherwise, the cars/systems have to be smart enough to hold traffic in sidings while opposing traffic clears. Not really a challenge.
As part of a long-haul system, not so much.
OTOH, if it's for dedicated customers on each end, and the cars are aggregated into trains - likely locomotive hauled consists - it could eliminate local switching on each end. Railroad delivers the cars to a siding from which the cars can be dispatched and returned after which the railroad picks them up again to return.
I'm not going to say it won't work, but it's not any sort of a blanket solution for anything.

But even though it is rated for full capacity of ordinary freight cars, won’t it have to divert some of that capacity from the cargo load to transporting the weight of the batteries, motors, gearing, heavier trucks, electrical control equipment, enhanced airbrakes, autonomous running equipment, lighting, fairings, and other technical equipment associated with locomotives?
daveklepper even with dorect (direct?) competitors working together to realize profitable intermodal lanes that would not be profitable with either railroad working alone.
Doing that can get you some time in a prison.
daveklepperThe two ways railroads can increase business profitably are: Lower costs and time for truck-train and train-truck transfers
The specific niche is one we've discussed many times here, including with regard to Murphy's lumberyard: bulk or low-volume commodities, where aggregation into locomotive-hauled trains isn't and effective use, or where last-mile switching is difficult or expensive to conduct. Whether you have a one-to-many or many-to-one situation, it's clear that a cheap method of running cheap railcars either in an ad hoc network arrangement or platooned as necessary will have value. That value is completely separate from the kind of QoS concerns traditionally involved in intermodal service in the past, or in the current least-least-common-denominator double-stack commodity-priced land bridging we now often see.
I still see major issues with the idea, not least of which is overall system cost -- I presume though that the development team and the prospective customer that has committed to $30M worth of the things have evaluated and understood this well enough to reach an adult decision. I would be more concerned with incident crime or vandalism, particularly if the designers are naive enough to make or use components with high 'street' demand and resale value...
In addition to the time-out-of-service issue, serios enogh, there is a much larger issue.
With the abandonment of much branchline and seciondary track, most shippers and receivers aren't even adjacent to a rail line, let-alone actually have a usable siding. So autonomous freifgtcars may find a nich market in large intra-plant railroads, but continental or national application is very doubtful.

I haven't seen anything from Intramotev or Idealab that indicates TugVolt is anything other than converted separate railcars. No articulation, no stressed containers, no fancy self-aligning modules, no underfloor batteries -- about as far from an 'integral train' as you can get.
I suspect that in practice the fancy 'streamlined' end casing would be replaced by box housings with the control suite and battery banks, with a platform above reachable by ladder or stairs so that someone with a RCO or analogue can securely control movement. In a hopper I expect a great deal of the machinery to be 'tucked' under the slope sheets.
Intramotev's Web site is still mostly a 'teaser', with no technical discussion at all that I can find. (Irritation warning: you have to swipe up and down but the pages slide right to left, one of the more irritating IxD fails I have had to encounter...)
Perhaps someone would care to contact Cathcart in Columbus to see if he knows more about the obvious details, including the issue of 92-day for electric vehicles. My guess would be that if you got any answer it would be to invoke a NDA, but someone like Ron may just have the chutzpah to try...
Please keep in mind that powered railroad rolling-stock of any description requires roughly five times the out-of-service tine and worker-hours than non-powered rolling-stock for Federal-required inspections and for maintenance.
Steam engines sometimes had "booster engines" on the trailing truck. It would only engage when the extra power was needed.
A similar arrangement could be done with freight trucks, although this does introduce a measure of mechanical complexity, which will be a maintenance headache.
OTOH, recall that the traction motors on a Diesel-electric are always engaged with the axles. If they aren't providing power or braking, (ie, if dead-in-tow), they simply free-wheel, which could happen with this particular concept.
It would appear that the designers saw pictures of the truck arrangement on GA8's without being aware of the actual arrangement of the traction motors.
TugVolt is completely different from Parallel Systems; all it does is motor existing freight-car trucks to make them self-mobile, and allow 'enough' autonomous or remote control that cars or trains of cars can operate between specific points.
The problem is that there appears to be handwaving going on in their promotional material: they show, and their material describes, trucks that operate 'normally' when the cars are being towed normally by their couplers in ordinary railroad service -- I see fundamentally unmodified three-piece truck sideframes. You do not casually 'put motors on these' and voila! get self-propelling 283k# cars moving themselves safely, if indeed very far at all.
Not sure if this was one of the items Euclid was referring to in the other threads, but saw it when looking at the articles on the CP Hydrogen loco

Their initial primary use model seems far more plausible.
