  A lot (most?) transit systems in europe are completely at capacity at peak hours. In London and Paris they are at the physical limits of what you can do, say a train every 90 seconds. You cannot physically increase frequencies above that. I also don't think you're doing a lot of reading in crush loaded trains, but whatever. I take the train every day but it's not like a nice relaxing intercity journey, in London rush hour it can be complete hell and is completely not productive when you have 4 people in a sqm.

    You can increase frequency in London on many lines (e.g. the Northern) by resignalling, and TfL has been looking at doing so. But it ain’t cheap. See London Reconnections passim. But the bigger wins are more active travel (by providing segregated cycle routes) and moving more Tube journeys to the shoulder peak.
