I suspect Tower Hill to Gloucester Road, on the
District and Circle Line of LUL, is even busier.

I doubt that this is the busiest part of the tube, because it has flat
junctions at both ends.

At one point it was certainly the busiest bit of the subsurface network,
with IIRC 33 tph in each direction during the peaks. It might well have
been the busiest point on the network. Unfortunately, "Sharing the
Circle" seems to have disappeared from the Web.

However, if we're counting the number of trains passing a station,
either Finchley Road or Hammersmith (D&P) would be my first suspect.
