In the 1950's I lived in North Harrow and think the Met had only two
tracks
running between Harrow on the Hill and Moor Park and beyond. A recent
photo
shows a second set of lines on the south west side of the station.

That could of course have been the BR (ex-GCR) lines. South of and including
Harrow-on-the-Hill they are on the south-western side of the formation,
giving Harrow three island platforms (from south to north Marylebone
down/up, Met down and Met up). I can't remember whether this arrangement
continues north of Harrow Junction.

Clive's UndergrounD Guides web pages say "Traffic on the Metropolitan
was
heavy enough that it was quadrupled from Finchley Road to Kilburn in
1913,
Wembley Park in 1915, Harrow in 1932, Northwood Hills in 1961, and
Croxleyhall Junction (north of Moor Park) in 1962." I am right in
understanding this to mean that the second pair of lines were built in
1961.

Does any one have information on this second set and/or any images of
their
construction.

Sorry, no images, but the dates would be right, co-inciding roughly with the
intoduction of the A59 and A60 stock (IIRC, "A" for Amersham and the years
'59 and '60). Not sure if the reference to "second pair" of lines is
strictly correct. Certainly the Met south of Harrow is paired by direction
(very efficient use of space, with the slows in the middle, because you can
use a single island platform where there are no fast platforms, as at
Northwick Park for instance, and one island for each direction where fast
trains stop, Harrow for instance). I think this continues north of Harrow,
but I can't remember exactly. So I would guess that quadrupling was achieved
by a new track on each side, BICBW.

Stopping pattern for the fast Amershams was Finchley Road,
Harrow-on-the-Hill, Moor Park, then all stations - is it still? The
indicators at Finchley Road always used to have facilities to indicate a
train that didn't stop at Harrow-on-the-Hill, though I've never seen this in
use - have any trains ever missed the Harrow stop in regular service?

[OT] Many years ago I used to drink with a work colleague whose standard
excuse for not buying his round was "must catch the last fast Amersham", and
I've never felt quite the same about the line since.
