the extended East London Line.

Just out of interest - is this line going to be dedicated to ELL services only
or has the infrastructure been set up so it can be used as a short cut by
freight trains and maybe a diversionary route for other services?

Would tight clearance in the Thames Tunnel be a limiting factor? Other
than that, I can't see what would stop other trains using the line.

I don't think there are any significant gauging issues there - I suspect the
only practical thing keeping diverted passenger services off the route would
be lack of capacity - it is intended to run the 16 tph 7/7. But in dire
emergency you wouldn't think there'd be a problem getting at least any other
DC Electrostar variant through.

Having said that would there ever be a practical requirement - the only
thing I can think of might be ECS moves to recover stock after an emergency
Thameslink closure (or vice versa) but they can use the WLL?

Someone will now say it can't be done because the core ELL isn't part of the
'national network', but IMHO that is purely an administrative obstacle.

Can't see Freight though, although it would be gauge (and gradient)
dependent too, only 92s would really be suitable traction, and they don't
seem to have route cleared them in south London at all yet...

I think if they'd had a bit more cash they could have at least added a
third line along the stretch from Dalston to wherever possible
southwards - after all that trackbed used to have four tracks - I think?

What would be the point? You could hardly get M I Brunel (even assisted by
his son) back to dig you another tunnel under the Thames.

The line was widened over the years, but IIRC four tracks ran all
the way northwards from Broad Street station to Dalston Junction.
IIRC they were called the No 1 and No 2 lines and it was the former
which were electrified. At Dalston Junction four lines turned west
and two lines turned west. The electrified lines were used by
services to places like Watford Junction and Richmond, the
non-electrified lines were used by services to places like Welwyn
Garden City and, in earlier times, services to the docks.
