Eventually TfL should withdraw services north of Moor Park. They are
clearly clueless with regard to the needs of suburban passengers.

Ideally the Chiltern Route to Aylesbury should be electrified at
25kV. Chiltern would take over all Metropolitan services north of
Moor Park.

One of the early iterations of Crossrail involved a branch from Old Oak
Common, joining the M&SWJ and then linking with the Chiltern Met line at
Neasden. It would then have taken over the Met Fast Lines from
Harrow-on-the-Hill, and all Met services (apart from Watford) beyond Watford
South Junction. All, out to Aylesbury and Chesham, would have been
electrified at 25 kV AC OHLE. LUL would have retained Uxbridge and Watford,
and Marylebone would have retained all Joint Line services. In the event a
business case could not be made for electrifying out to Aylesbury, and
Heathrow became a much more important destination for Crossrail.
