Network Rail's press release shows the track work in progress, I can't
work out from the pic if they've laid two tracks or just the one. Can
anyone clarify?

I doubt that "normal service" could be restored with single-line working
so, while it is difficult to be sure, it looks to me as though they have
laid one new track on the south side, which will become the temporary down
line, and they are checking the gauge of the old down line, which will
become the temporary up line.

If I'm right this presumably means that the infrastructure damage is
limited to the arch on the north side (left side in the latest photo), and
that it has been determined that the rest of the tunnel under the line is
OK.

I'm pretty sure it is two new tracks now. Those location boxes and the
concrete troughing look as though they are in the original position., Aerial
views show them on the down side at that point. In other forums they are
saying the speed limit will be 20 mph, so that will affect timings, but it
should still be a full capacity route.
