4tph is also the off-peak frequency to London at Richmond, Ealing
Broadway (District) and Rickmansworth outwards. I accept that that's a
small proportion of stations.


Richmond and Ealing Broadway both have 6tph off-peak. Rickmansworth -
Amersham has 6tph if you include the Chilterns. The only stations of LU
with less than 6tph are Chesham (2tph), Woodford-Hainault (3tph),
Kensington Olympia and Mill Hill East (4tph), New Cross and New Cross
Gate (5tph each).

My apologies about Richmond and Ealing - I didn't check beforehand. But
Rickmansworth only has 4tph direct to central London between 10am and 3pm
weekdays, including the Chilterns - Met departures are at xx00 and xx30,
Chilterns at xx10 and xx40.

You must be looking at an out of date timetable. It has been 4+2tph for at
least a year - see

Looking further I see that the TfL Interactive Map http://map.tfl.gov.uk
gives the times you quote from a timetable poster dated 29/09/02. In fact
none of the timetables on the map seem to have been updated for some time.
