Given that the peak flow point on the Metro is the tunnel from Rosslyn to Foggy Bottom (and I believe service already operates at peak signal/power infrastructure capacity in the tunnel), is there a plan for how to handle the increase in peak passenger flow from the westward Silver Line extension?

Are there signal improvements planned for the shared stretch to run tighter headways? Can some of the passenger flow be redirected over the Yellow line bridge? Are all trains on Blue and Orange already 8-cars in the peak, and if not could longer trains allow for widened headways to make room for Silver Line trains? etc.

I recall that in very long term plans the Blue Line would get its own tunnel and serve Georgetown, but such a project is probably at least as expensive as the Silver Line and thus a decade or more off.

I suppose to some extent this issue could be alleviated by continually raising the peak-of-peak surcharge to tamp down on peak demand, but that's hardly the ideal solution.
