That sounds more like Dr Who.

And in 1986's "The Trial of a Time Lord" the Doctor visits the future
where
Earth has been devasted by a solar flare and survivors live in "Marb
station", a complex built in and beneath Marble Arch station (although
the
set for the actual remains of the station bears little resemblence to
Marble Arch).

After my time.

Not very realistic - as every one knows, in the future the Doctor would
have landed up in a Crossrail tunnel....

Maybe, though in 1968's "The Web of Fear" the tube maps shown are for 1968
(lacking the Victoria and Jubilee Lines) despite dialogue that dates the
story as at least 1975 ("over forty years" after "1935").

But the series also expected the BBC to have a third terrestrial channel by
the erm 1980s at the latest (some of the dating is unclear), a British space
programme with regular trips to Mars and even shots to Jupiter in the same
period, the decimal system to have ten shillings in the pound, five pound
coins would be in circulation in the late 1990s bearing the head of a King
and that Gillian Taylforth would still be in EastEnders in 2013 (although
Letitia Dean keeps making and breaking that prediction as well!).
