      they already do 4min headways during rush hour on the blue line right?

      Sounds about right. Ultimate practical headway capacity on almost all signaled rail lines is always around 3 minutes = 20 tph.

      OL should be able to get closer to 30 since there is no branching. Terminal space and lack of trains are a big issue. BL is the same but better off than OL. RL could do more but the Alewife switch and the Harvard curve slows things down.

      It’s hard to sustain 2 minute headways without delays in actual operation. That’s why it is rarely attempted.

      What does the Moscow Metro do that allows it to sustain nearly 40 tph?

      Threatens the train ops families to keep them moving.

      dodging; if it were impossible to do 40tph then no amount of threatening would change that

      It probably uses different signal rules and block lengths than we do. Their ridership may be more spread out between stops or times of day than in US which would lower maximum station dwell time. Lastly, they are probably ignoring any type of recovery time.

      Chicago El and CA&E used to run on one minute headways using line of sight rules. See the booklet “Cooperation Moves the Public” for details.https://www.amazon.com/Cooperation-Interurban-Historical-Society-Dispatch/dp/B004B7PZA8 …

      I believe the old Bay Bridge railroad did 57 tph, with a primitive form of train control.

          Short, slow-moving trains though.
