What about using some type of pod system that you get into, and then get picked up by the train while moving. Then when you arrive at your destination your pod jumps on a different track and comes to a halt at the exit from the station. This would also allow for a inter-train exchange point, so you stay in your pod from start to end of your trip. The pods could be individual, or multi person, and hook on to different train wagons. The entire system could be close to 100% automated, and inter passenger crime could probably be lowered.

I think it could be done relatively easy, if the train slows in the stations etc. We have the advantage that it could be speedup in the future when the tech allows it.
