A certain amount of the track work and signalling already exists for
Cambridge Science Park's bay platform, perhaps surprisingly. They are left
overs of the former St Ives branch, including what will become the starting
signal(!).

I would be shocked if any of it was still usable barring the odd bit of
conduit here and there. The last train ran over 20 years ago according
to t'interweb.

You are probably looking at the records for the line to St Ives. The new
station is being built on the old Chesterton Sidings, which continues to
have aggregates traffic to the Lafarges site.
