On Monday morning, an entertaining driver on the central line informed
us that this was "the 09:18 from Woodford, calling all stations to
West Ruislip, due to Stratford at 09:xx, Liverpool street at 09:yy,
and Holborn at 09:zz"

While this is guessable (Epping to White City takes bang on an hour on
most trips), I am dimly ware that there are working timetables for
tube lines. How often to trains run to these times, and is it possible
to get a copy of these? With a 10-15 minute wait at the extremeties,
even at 9AM, it would be nice to see when trains are due. Some lines
have a live ETA, but the central line doesn't. The WAP service at
http://wap.tfl.gov.uk/tfldepboard/ tends to break down whenever I try
and use it in anger
