What you’re suggesting would be a system similar to what is used today on rollercoasters.

  Is it? I haven’t been in one recently, but I would get people out on one side, and in on the other (which typically isn’t possible in existing subway tunnels) Rollercoasters have a few other advantages: - exits at every row of seats. - less crowded (no standing passengers, never three people on a two seat bench) - at every stop, everybody gets out, and everybody gets in. - passengers typically are relatively fit (no small kids, no elderly) - no luggage. That simplifies the process quite a bit.

    Of course, but rollercoasters also frequently have much more money to spend on security features, so technology first seen there shows up a while later in public transit. E.g., modern signalling that replaces the old block signalling, or the station door systems to let people in/out which now are also in major subways around the world.
