I heard a story that new Met Trains are going to have a form of
air-conditioning fitted (although for obvious reasons it won't work
underground). Does this mean the Met Line is finally getting new trains
(that don't squeak?)
New trains are planned and yes I heard to they would have a form of air
conditioning. There are plans to standardise the stock on the Met,
Circle and District. I believe we won't actually see any new trains for
several years, so we have to put up with squeaking and more for quite
some time yet.

For all the sub-surface lines, switching off the air-con when underground
should still help the passengers using the underground sections as the air
inside the train will take time to heat back up again.
