I was standing at St Pancras Low Level the other day and saw that from
the Northern end of the platforms you can see a couple of bored
tunnels. One is to the left of the Midland line and the other is to
the right. Both are fenced off and neither has track laid.

Would I be right in thinking that these are the eventual connections
to the ECML? I had assumed they would be cut-and-cover rather than
bored. Does anyone know any details?

Yes.

Sorry, not really. I think they're cut and cover at the northern end
though - see this bird's eye view:

The SPILL box itself was built as cut and cover, but that view above
clearly shows why you couldn't realistically cut and cover all the way
to the ECML.

This picture might also be helpful, as it shows where SPILL is
positioned, and hints at the length of tunnel required to meet up with
the ECML (aligned left to right at the very bottom of the map).

Interesting. The positioning is pretty tight - avoiding the original
bits of St Pancras station, the British Library and the housing to the
west of Midland Road. I'd be interested to know how far if at all this
alignment deviates from what was there beforehand, i.e. the
subterranean course of the Thameslink line before SPILL was
constructed.

Almost identical I think.

Indeed. I used to travel in via Thameslink, and the platform area was
visible throughout, with big white/grey fencing separating off the
(then to be) platform areas. Always quite nice to see how things were
progressing each day (as much as you could see in the gaps anyway)
before my mad run from KXTL to catch my KX train (ironically, then in
the main shed, now I come via the Met, in the suburban shed). C'est la
vie.

The northernmost part is cut and cover, but the rest was always planned
as bored. See:

And if, as some suspect, they never see traffic as a result of cutbacks
- they'll always be bored.

Cutbacks to which programme, Thameslink? Is that really likely? Surely
now that the tunnels are built, the connection to ECML isn't that
extensive?

I did wonder how well the flat junction onto the ECML would work
though.

Yes, but they're only useful if the very expensive works to open up
capacity through London Bridge and Bermondsey go ahead. There's a
reasonable argument not to go ahead with this whole phase of works
once the current phase (12 cars at Farringdon and Blackfriars) is
done.

Holloway flyover plus all the bi-directional signalling in the area
means you have a lot of flexibility to avoid conflicts.
