A 444 at Woking will be less packed than a 455 at Clapham, IMX. And
given the regularity of many Southern Region commuters' commutes, I
don't think advertised vs unadvertised makes much difference.

I've seen an article in the SWT magazine that described why they don't stop
in the up direction... IIRC a call takes about 1.5 mins which eats a path.
To switch to the slow lines to call eats even more paths.

Surely if the train behind is also stopping at CJ, then the net eating-
of-paths is 0?


No, because you can get less trains through the station per hour. If
trains take 3 mins (20 trains per hour) to pass though a piece of line
without stopping and you add 1 1/2 mins to that (4 1/2 mins total),
you will get less trains per hour though that section (13 1/3 trains
per hour). Signalling alterations will change the calculations, but if
the line is signalled for non-stop services then stopping will always
mean less paths available.
