Does freight stlll use the Harrow to Amersham section of the

I doubt it - there would be nowhere for it to go. Heading eastbound
through Harrow (onto Network Rail), the only place you can get to is
Marylebone.

The Dudding Hill line (from Neasden to Acton) can only be accessed
from the Northolt Park direction.

How do the binliners get to Aylesbury?

Via South Ruislip and Little Kimble.
