Underground, urgggh!

So what IS it with the London Underground?
On paper it looks very comprehensive. It goes to a lot of places. That’s good. However…it’s not air conditioned (since I guess it doesn’t get that hot here) and the cars are cramped (I’ll take a pic before I leave to show just how) and it seems to always have things happening to it.
Let’s see, just in the past 24 hours, there has been the following incidents:
Person under tracks (last night)
Line shut down because of signal failure (today)
and the most disturbing…
Train derailed on Central line.
And don’t even get me started on how bloody expensive the Tube is!
