Brain fart time: how about a transit system composed entirely of escalators ? When you board, you take a slow treadmill that runs in parallel to a faster one, and that in turn to another, gaining 0.3-0.6 meters/second on each lateral skip. You do the reverse when approaching your destination.
An treadmill running at 10m/s with pairs of people spaced at 0.5m has a capacity of 40 people/second, or 2400 people per minute, or one large train every 30 seconds. The average speed is higher and you no longer need to wait for a train. The only very small problem is the prohibitive cost with existing tech.
