  The reason why I noticed this was the timetabling from Mitchelton
to Ferny Grove to Mitchelton is very interesting.  In particular service
1778 originating at Ferny Grove

  Ferny Grove: 5:29pm, Keperra: 5:32pm, Grovely: 5:34pm, Oxford Park: 5:35pm
  Mitchelton: 5:41pm (6 minute gap here).

  Service 1E67 is running north leaving Mitchelton at 5:40pm,
Oxford Park 5:42pm, Grovely 5:43pm, Keperra 5:44pm and Ferny Grove 5:47pm

  Remembering my airport trip to Domestic on Monday, I'm sure single
sections do exist between International and Domestic.  Anyone else
agree with this?

  Thanks for the rest of this, I'll be storing this and reviewing it.
Lately I've been attempting to retimetable some of the lines on paper
in my spare time.  So far I've have had a lot of "theoretical" collisions
between various services everywhere ;-)

  I noticed in a 1995 timetable that the Cleveland line used to be
Green (continuing to Caboolture), and that the Ipswich line was blue
(continuing to Shorncliffe).

  I've crossreferenced this one with the Doomben/Cleveland timetables,
both are printed at 7:09am.  You are right though, the timetabling from
Vulture St to Sth Bris has changed.  One day I'll catch this service
and look at it from South Brisbane on the monitor (be interesting to
see if it actually runs on time).

  Agreed.  The reason why I worked all of this out and forwarded it to QR
was I considered numerous interchanges to be badly timetabled.  Some being
too short, and others far too long.  With 21 possible interchange times
(not including the Sunshine Coast and Airport lines) it isn't possible
to have good times for all of them.  However more than half of them
I consider excessive (having to wait more than half the time between
scheduled services).

  Actually I've noticed this, as I use it extensively for journeys everywhere
(both via Tennyson and South Brisbane).  The fare information comes in useful
each month when I review my monthly train travel to work out which monthly
ticket I should buy (I can't buy one ticket to cover all my journeys).
