30 to 35mph tunnel, 60 above ground.

Very anecdotally, I would have thought that longer tunnel stretches (eg,
Finsbury Park to Seven Sisters) would get up to faster speeds? It SEEMS
to hit some sort of decent speed in that stretch, anyway?

SEEMS to, is about right. Travel on either the first train in the
morning or the last at night when the tunnel lights are on, sit on the
opposite side of the train and watch them go by, it's a very informative
little exercise.

Unlike earlier deep-level tubes, the Victoria Line is designed for a
maximum of 50 MPH. I don't know what the 67 and 09 stock reach in service.
