I appluad the sentiment (and was pleasantly surprised by how much of
the south London network qualifies), but isn't there anyway they could
be made both clearer and less ugly? Perhaps by using a different colour
for each London terminal (and Thameslink), and use broken lines instead
of less bold ones for infrequent services. Then those routes qualifying
for the map because of services to two stations (the Bexleyheath line,
for example) could be shown by running two sets of broken lines
together to form a whole one.
Idle thoughts on a weekday afternoon, I know.

I still think their waterline should be at least eight trains an hour.
Four is not frequent.

I'd advocate six, but I think 8 is unrealistic - major stations aside
(East Croydon, Wimbledon etc) how many routes have 8tph?

London Bridge to Forest Hill and return - 12TPH.

Put simply - build them. You're right that few have 8tph, but the
setting of the waterline at four seems more a decision based on
marketing than it does the semantics of the word "frequent".

I think a 15 minute interval is just enough to qualify - after all,
given that the average wait should be 7.5mins, that's just enough time
at the big terminals to buy a ticket and find the platform if you're
unfamilar with the place.

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.

It is interesting that 6tph is "standard" offpeak Tube frequency on
outer London Tube services like the Central line's West Ruislip branch
or the Piccadilly's Rayners Lane branch, whereas 4tph is deemed
sufficient on National Rail, even at inner London stations like
Loughborough Junction, Streatham Hill, Deptford and St Johns.

I think worst-case time is more important than average - i want to know
i'm not going to have to wait longer than a given time.

Basically, where NR and LU share (how about the Bakerloo?) - it should be
banned!

And no, Ealing Broadway isn't shared, but that's not important right now.

This must be some new meaning of the word 'interesting' of which i was not
previously aware - a synonym for 'criminal', i take it .

Add most of the West Anglia line that list (not Hackney Downs or Tottenham
Hale, though) - in fact, i think it's even less above Hackney (Cambridge
Heath etc).

6 tph should be the benchmark for 'frequent' service. 8 tph should be an
aspiration. 4 tph is absurd.

Also, those six trains should be evenly spaced. Perhaps the rule should
actaually be no more than 10 min between departures; 6 evenly-spaced tph
would satisfy this, but 8 tph would be needed if they weren't even.

Oh, and the map should deal with the multiple-destinations problem by
treating services to different destinations as separate lines; i don't
think a station on two infrequent lines should be count as frequently
served, but i don't think it's entirely clear.

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
http://tube.tfl.gov.uk/content/first...oundWTT318.pdf

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.

London Bridge to Forest Hill and return - 12TPH.

How do you work that out? Seems to be 6 to me, 2 to Victoria via Crystal
Palace, 2 to Caterham and 2 to Sutton.
