My vote has to be the Northern Line, every time I travel on that line I
always have black 'dirt' in my nose.. no its not bogey/snot!

Belsize Park station has the highest dust quantity ISTR.

Seeing that it seems to cling more to magnetic surfaces, it must contain
a high proportion of iron so at least we won't be anaemic on Section

The bakerloo has plenty of 'black cocaine' around, though I expect the
northern is worse, if only because it has been open longer and had
more time to build up.
