Now you see the floor pattern of these train cars

That hall is not large but the left end you have another bathroom since trains have those outside suites at the ends of cars for people to use who are wandering through the train.
Now if your train car allows through traffic are you going to let them use that bathroom? Probably, so then now you have no place at all for your Tesla wall unit that connects you with the library of objects, and manages your back door.
Even 5 inches is too wide for those hallways.

So it either has to go by the back bathroom or in one of the suites.
Of you just use the main transporter at the one end.
But I like using two so that again you have a redundant system.
So there is a maintenance closet and it can go in there or close to there or in that bathroom or close to there.
It is 4 feet wide.

Now the batteries are not critical there because under your train you have a bunch of them.
BUT standard objects are standard objects and it has a plug and always at some point somewhere you need it to do what it does elsewhere and so they are kept the same upgraded in unison and easy for admin to manage using automated software.

So the entire system is automated, and we go to the beach on holidays.

And if you need an override someone will handle that with their Iphone.
You know how things works not everyone can call to get an override it has to come through channels.
Some lesser admin or team manager might have clearance to do what you need to get done.

We try to second guess what you might need done and empower the team leader..
So whoever that disk that is parked there with a subnet coming off it that is a team leader he or she decides who has access to what in that subnet.

As a citizen of our realm, everyone gets a disk on a track and a door and a moonship that is 350 miles in diamter.

And they get a desert island.

A very basic starter island that you upgrade redesign share modify and live in also as well as your train car.
So the train cars are really for the starfleet personnel, and airship personnel and family and most people would live in their own moonship.
With their family.

So each citizen gets a disk a disk can make a moonship we can copy and paste anything into them including mansions and yachts whatever the library will permit you to have as he shifts the responsibility there to the library away from king and crown to user run committee based system.
