Pretty neat.

Yeah, but you'd better be sitting down and buckled in when the Express gets there to pick you up. It's bound to be a rather abrupt take-off, and the same for the people in the other capsule that are stopping 150-KPH to zero in a few hundred feet. Colonel Stapp had it easy...

And if something goes wrong in the transition, like the disembarking 'passenger capsule' doesn't disengage from the main train properly and smacks into the accelerating capsule, it has the potential to be seriously messy. (Eeeewwwwwwww.)

Nice idea, but why would the bottom half have to be so long, unless they are using the length as an acceleration system to gently accelerate the new top car up to speed with the lower half and slow the loosing car down before arriving at the station. 1.5 billion volunteers.

Bingo! The long track on the train is to accelerate the joining transfer capsule up to speed gradually as it slides toward the rear of the moving train. And the long elevated track before the station platform is to allow the departing the main train transfer capsule to slow gradually before it gets to the platform again.

And the main train has to be long enough for all the arriving passengers to go "downstairs" and take a seat, and allow the passengers departing at the next stop to rush upstairs to the transfer capsule and get their luggage stowed and themselves strapped in.
