Can I ask why they have a loop anyway?

Would it not be possible and simpler to have just some more
terminating lines where the trains can be reversed back to
Civilisation?

Because a loop is quicker as the driver does not have to walk from one end of
the train to the other.

Once the train is ready to depart the SB platform, it would only take a
minute to get round the loop to the NB platform and be ready to pick up
passengers. The time to do the same thing via the siding (without
double-ending) would realistically take ten minutes. If only one siding
was used, this would reduce the terminating frequency to a train about
every 10-12 minutes. It would also block the Bank trains NB and SB to
Morden when the move was made to / from the siding.

More sidings could be built to give a greater terminating frequency, but
the additional cost, including the extra signalling etc. would probably be
many times the cost of building a loop.

The Kennington loop also has the advantage that passengers can be taken
from south to north if required.

Thanks for the answers folks, sensible when laid out.

Wonder about the land costs now though, when the loops were made I
assume that things were a bit different.

A simple solution would be to put a switch from that center siding to the Nb
track from Morden.
Back in the sixties we regularly reversed Bank trains through that
siding, what has happened to stop that, as once in the siding you were
clear of both running tunnels?

As it's all underground, there would be no land costs as such, just the
expense of the tunnelling work. However there would need to be access to
the new work and, unless it was only carried out during non traffic hours,
there would have to be an access shaft as happened at Angel and London
Bridge. A suitable location would need to be found for that.
