Are they ever going to figure out air conditioning for Tube trains?

Pump the heat out of the trains into the tunnels and stations. What
could possibly go wrong?

Eurotunnel manage something like that in the Channel Tunnel, and they
don't have stations every few hundred yards where they can remove the
excess heat generated.

But, the holes that the trains run through are vastly larger than tube
tunnels - and they have the service tunnel as well. Much more scope for
cooling if needed!
