The main benefit of the Croxley Link is connectivity between South
Bucks (on the Met) and the WCML and vice-versa.

To that end, perhaps Overground services from Euston could reverse and
continue in an Amersham direction.

....now that's an interesting notion I'd never considered.

My "pet" proposal has always been an orbital route, the easiest bit of
which is Rickmansworth to St Albans (primarily requiring a dive under
at Watford and the Croxley Link), but given the dive under isn't on
the cards for an amount somewhere between never and not likely, the
concept behind splitting off the Met's Watford branch still holds a
conceptual interest.

Given that TPTB seem to want to turn the Met into a normal tube line
line with just two all-stations branches from HotH to Uxbridge/Moor
Park, then slicing off the Rickmansworth-Chesham /Amersham services
and handing them over to a service operating from Watford Junction
seems reasonable (and the LO stock already has the required ability
for operating over the 4 rail electrification), and the LO service
seems to be about the right service level for that area, with the
ability to have additional services running between Watford and
Amersham/Chesham if required. Rickmansworth would need a *lot* of work
to enable it to handle the interchanging passengers though, and
Chiltern would need to beef up their services dramatically to handle
the loads heading into London. Probably would enable them to take over
the fast lines though, leading to potential speed improvements (and
maybe OHLE).

....another great reason to have the Chiltern line to Princes
Riseborough as the 2nd western branch of Crossrail to free capacity
into Marylebone for more Birmingham and Aylesbury via Amersham
services I say
