Earlier this week when the discussion started, I was reading it on a Denver CO light rail coming back from a trade show. We were going about 70 MPH passing all the cars of the freeway. It works quite well. One thing I've always thought could be done with trains, whether commuter or long distance, would be to have a self-powered train car at each station. People wanting to get on the train would board this car. People on the train who wanted a particular stop would get into the last car. As the train approached the station, the last car would disconnect and roll into the station. The car that was in the station would then catch up with the train and join it. Passengers not wanting the next stop would move into the rest of the train. What slows trains down, in my opinion, is all the stops. This would avoid that delay.
