Back to my old stomping ground in the Northolt / South Ruislip area.
Get on Central Line at Tottenham Court Road (avoiding blocked subway near Andrew Borde Street).
Get seat immediately, bury nose in newspaper.
Look up as train pulls into Northolt station to terminate, 29 minutes later.
Unremarkable except for being remarkable. Why did I hardly ever have such a good journey home when I lived there?
