Not really possible. However, a plan was proposed here many moons ago to
four-track the NLL throughout, from Stratford to Camden Road west
junction; there's room in the formation to do it, with apparently only a
modest amount of land take needed towards the eastern end. With a flyover
at each end, you'd have a dedicated, grade-separated two-track freight
route across London, taking freight trains out of the NLL picture
altogether.

You might not need much extra land, but widening the formation east of
Dalston is surely beyond what's practical?

I've probably not been paying a lot of attention but even trying to get
4 tracks through Hackney Central and under the mainline (Hackney Downs)
looks like a pretty tall order to me. You'd certainly be demolishing
property in the centre of Hackney including part of Clapton Bus garage
to get 4 tracks there unless I am really underestimating how wide the
alignment is. I'm not very familiar with the line east of Hackney
Central but again I think there is property close to the alignment the
whole way and I don't recall it being 4 track in the past. For those
who know better then I'm happy to be updated on what the formation is
really like.

West of Dalston I'd fully agree that 4 tracks all the way to Camden Road
is sensible and should be done with appropriate flexibility put in place
to allow passengers trains the ability to "get round" problems that
might occur on their usual 2 tracks.

Admits to working for London Underground!

Could the CTRL tunnels from Dalston to Kings Cross and then onto NLL
be used for night-time freight ?
