Does anyone know why the bridge carrying the LU eastbound lines (left)
is so much higher than the bridge carrying the LU westbound lines
(centre), and why the Chiltern lines (right) are slightly lower again.

The lines look to be roughly level with each other at Kilburn station to
the east and at Forty Avenue to the west, which are the next nearest
places where the lines go over roads.

I think that you've mis-identified bridges, Basil. The one you identify as
a bridge carrying LU eastbound is just a covered way to the side of the
railway lines. To the "right" of this covered way are three two-track
railway bridges.

Gosh.

Thanks to both repliers.

Looking at birdseye view on Bing.com/maps I note that there are spans
under all 6 lines and another span that has no lines on it. That
seems to be the one at the left of your google view. I deduce that
the Chiltern line and westbound LU lines, the southernmost 4 lines,
share the same level, all being 19th century lines. (by the Met and
Great Central Railway). The eastbound pair were probably added later
by the Met with just a little more road clearance. Why the most
northerly span with the greatest road clearance and no rails was
built, or when, I have no idea., Did it ever have rails?
The other bridges you mention - is the road clearance more generous?

Possibly part of the approach to the yard at Willesden Green. There is
a lot of spare ground on that side of the railway starting from the
bridge over the (un-named ?) continuation of Churchill Road including
a cable bridge with no track below it.

you use the top right control to switch to the OS 1:25k backdrop. (God I

The 1950s 1:1250 maps on the NLS website give an even better
impression of how much there was in the way of sidings in the area.
Unfortunately it is where four sheets join so the railmaponline
version saves doing a mental jigsaw. Winding further back to a 1920s
map has a couple more sidings even further west extending as far as
Dollis Hill station on what is later shown as just a bit of raised
ground.
