Here's another thing - you might consider somehow showing the
four-track nature of the Metropolitan north of Wembley Park; Clive
explains it all:

But basically, if i've got it right, the line splits into fast and slow
pairs just after Finchley Road, with the slow pair going through
Preston Road, Northwick Park, Harrow on the Hill, and then heading to
Uxbridge, and the fast pair going past the first two stations and in to
Harrow on the Hill.

A bit of confusion here - the Met splits into fast and slow lines just south
of Wembely Park, with the slow lines in the middle and the fast lines on the
outside. Preston Road and Northwick Park have a single island platform
serving the slow lines. There is also a separate National Rail pair, used by
Chiltern.

At Harrow-on-the-Hill there are three island platforms, the southern one
for Chiltern, the centre one for the pair of northbound Met lines, and
the northern one for the southbound Met pair. North of Harrow the
Uxbridge branch leaves from between the northbbound and southbound Met
lines by a diveunder, and a flat junction takes fast Met terains across
to what had been the National Rail pair. This leaves the Watford line as
the continuation of what had been the Met lines south of Harrow. These
have platforms at intermediate stations, while the fast pair don't have
usable platforms until Moor Park, which has separate northbound and
siouthbound islands. So you basically have cross-platform interchange
between Met and Jubilee at Finchley Road and again at Wembley Park, and
between fast and sklow Met trains at Harrow-on-the-Hill and again at
Moor Park.

Okay, well put. I think i knew that, but i do get really confused thinking
about the Met!
