What noise, dust and pollution? Are you talking about trains or

What about Gospel Oak to Barking? There's freight on that.

In any case many freight trains on the electrified lines are
diesel-hauled. Currently, on the lines through Willesden Junction, all
of which are electrified, about three-quarters of the timetabled
freights Mon-Fri are diesel-hauled.
