There is an idea of having trains not stop but having cars that accelerate and decelerate passengers to train speed.
Bud:
please tell me this was not Musk's idea  :D
soldar:
I can see having the last car released at speed and slowed down to a stop on a side track.

And I can see another car speeding up and catching up with the train and then hooking up.

This could be repeated n times along the way.

Car catches up and hooks up to train. Passengers move forward into other forward cars. Passengers alighting at next station move back into last car which will be released and a new car will catch up. This process can be repeated along the way and the main train need never stop.

The problem is that there isn't enough room in a typical train for that many people to move. Especially when they travel with luggage.
soldar:
"Typical train"? This is not a typical train! This is a train that I invented and it is designed with the concept in mind. I cannot see the problem. People move between train cars all the time.

"That many people"? How many people is "that many"? Suppose the accessory cars can handle a certain fraction of the total train capacity, say 1/10th, whatever, so when capacity is reached for a certain destination you stop selling tickets for that destination. You know, like it's always been done. And how is having a limited capacity for destination X not better than zero capacity because the train does not stop there?

The only reason I can see for not wanting to allow boarding and alighting in intermediate stations is if the train can be filled with passengers from end to end. Then you would want to have additional trains to/from/between intermediate stations.

A train from Hong Kong to Peking with six intermediate stops of 15 minutes each will be adding 90 minutes stoppage plus accelerating and decelerating time. A train that does not stop gains all that lost time.

The notion that the problem to be resolved is moving passengers between cars.... I don't know, maybe I am missing something.
