In your dreams!

A proper timetable has to be designed with trains travelling on the best
aspect i.e.Top Green. In the underground this takes up to 3m30s to achieve
without any margins. If you want to design services go to the most congested
areas and see how long it takes for signalls to clear after the passage of
trains. Average these figures for each location over about 2 hours each of
Morning Peak, Evening peak and off peak and you get a workable basis for
your suggestions.
