Before you get excited, i assume that 110 tph is counting all trains
passing through, so both directions on both lines. But still, that's 27.5
tph. When we were discussing splitting the Northern line, the figures we
were kicking around were 22.5 tph in the current setup, and 30 tph with
the split. Was 27.5 tph ever achieved? If so, could it be now? If not, why
not?

I presume the 27.5 tph figure is the planned maximum when everything
goes to plan, and so only attempted during the peaks, and 22-25 tph
(not 22.5) is the realistic sustainable throughput.
