How do the express trains get around the slower stopping trains? Or are you going to entirely remove two thirds of the stops?! I don't think you'll have any risk of crowded platforms, it'll be far too useless a service to attract many passengers.

You cannot compare bus stopping times with tube stopping times. It's meaningless. But if you must, the average dwell time for a London bus is closer to 15 seconds. Which is actually quite remarkable when you consider you've got to pay as you get on. And there's often a buggy or two trying to negotiate the driver having parked too far from the curb. The peak and off-peak must be wildly different and make this single measurement pretty useless.
