But John Band said there were 16 trains doing GN - Broad Street in the
peaks! That's probably 8 tph, which seems decent. Now, that was from the
GN to the Canonbury Curve (well, the bit north of the curve proper - the
Canonbury Straight?), but all it would take is a pair of crossovers
south of the junction with the mainline to get those trains onto the GN&CR.

The GN&CR is in a deep cutting at this point, presumably deep enough to
go under the Canonbury Curve tracks to reach the old deep-level station.
Building a connection would have been (and apparently was) a major project.
