I certainly hope this turns out to be feasible. Now, if only they can
find a way of extracting surplus heat from inside tube trains and
pumping that into domestic heating systems! Central Line trains
should be the first. It has always puzzled me that eastbound Central
Line trains arrive at Stratford where the platforms are above ground
level, the doors open . . . . . . and the heat remains in the
carriages!

Because the platforms are even hotter?


No, because the train body contains far more heat than does the air in
the carriage.


Letting in colder air should help in the short term though.


Yes, briefly.
