There should be at least 5tph to Bourne End (ideally 6tph given that we
are talking about small Ultra Light Rail vehicles like Parry People
Movers) as current bus frequencies on this corridor are 6bph Loudwater,
4bph Wooburn Green & 3bph Bourne End. Current public transport frequency
to Maidenhead is 1bph connecting to the train at Bourne End. I don't
think anything less than 3tph would attract people out of cars.

With a passing loop between Cookham & Furze Platt, you could squeeze
5tph in each direction; that would give 2tph Marlow - Maidenhead and
3tph Wycombe - Maidenhead (with a separate 2 or 3tph terminating at
Bourne End). Two passing loops and you can get 7tph in each direction
(say 3 for Marlow and 4 for Wycombe). Maybe it would help missing out
some stops at Cookham, but I'm not sure of the figures for working that
out.


At that frequency you'd get some pretty vociferous objections from road
users at the level crossing in Cookham and the one(s) that would have to be
re-instated at Bourne End.

The Cookham one looks a potentially serious accident spot as well.
