In the early 70s

As far as I can remember the BR trains stopped at Moor Park Rickmansworth
and Chorley Wood only during off peak times.
They never stopped at Northwood, Pinner etc as they were on the slow lines
and BR did not use those. I think the section was quadrupled around 1961,
co-inciding with the introduction of the A stock, electrification
Rickmansworth - Amersham and withdrawl of the dreadnought stock and most
of the locos.


During the peak they were none stop from Harrow to Chalfont and Latimer.


And on Sunday BR ran an hourly shuttle from Amersham to Aylesbury and if
you were going to London you had to change and go to Baker Street.

I've been checking the archive. Initially on introduction of the A stock,
quadrupling Harrow to Watford South Junction, electrification Rickmansworth
to Amersham and Chesham, and dieselisation of the BR Marylebone - Amersham -
Aylesbury service, the off-peak pattern to Amersham - Aylesbury was:
BR hourly, Marylebone - Aylesbury, calling Harrow, Chalfont and all stations
LT half-hourly Baker Street - Amersham, calling Finchley Road, Harrow, Moor
Park and all stations.
Chalfont - Chesham half-hourly shuttle.
In the peaks the pattern was:
BR every 15 minutes, Marylebone - Aylesbury, calling Harrow, Chalfont and
all stations
LT every 15 minutes Liverpool Street - mersham, calling all stations to
Finchley Road, fast to Moor Park, then all stations. A couple of trains ran
through to Chesham instead of Amersham
Chalfont - Chesham shuttle half hourly, in addition to the through trains.
Metropolitan Main Line trains ran from Baker Street off-peak, and it was
only Watford and Uxbridge trains which ran from Aldgate.

After a few years the off-peak Baker Street to Amersham service was reduced
to hourly. When this happened, the off-peak BR trains began to call at Moor
Park and Rickmansworth.

Note that peak LT Amersham trains did not call at Harrow; there were also
peak Watford trains which were fast Finchley Road to North Harrow, and
Uxbridge trains which were fast from Finchley Road to Rayners Lane (in
addition to the trains which called at all Met stations.
