You are right.

You are right.

Which should be the cheapest option, though I assume there would still
need to be signalling work.

A better comparison might be the all-new station at Southend Airport,
which cost £16m in 2011.

East Midlands Airport station cost £25m and Cambridge Northstowe
Parkway (officially called "Science Park") is going to cost £26m.

Common features are that each have one platform plus one island, large
car parks and new access roads, and are built on out-of-town brown
field sites. The costs are therefore consistent with Southend Airport.

Presumably they needed new track work to accommodate three platform
faces?

In both cases the track was there before - the two fast and two slow
lines through EMD (I misremembered - there's actually three platforms
although one is much shorter), and the two fast and one siding/loop at
Science Park. But a certain amount of re-positioning to fit the island
platform is no doubt required in both cases.

Yes, the track would have to be slewed for sure to fit the island
platform in. Were new points and crossovers needed as well? That
would increase not just the track, but also the signalling cost.
Obviously the large car park and access road pushes up costs, too.

I'm pretty sure the through lines at Cambridge Science Park won't need any
realignment. The bay platform line will be new construction on pre-existing
solum.

Yes. One strength of the Cambridge Science Park plans is the re-use of the
St Ives branch exit signal which has been retained with no track alongside.

Corby cost £8.3m

One platform on a single line, and famously at the time they didn't do
hardly anything to the signalling of what was a lightly used
freight-only line, resulting in all sorts of operational headaches.

http://en.wikipedia.org/wiki/Corby_railway_station#Design_and_construction
although wiki implies there was road and car park building as well

It does have a car park (60 spaces), but it's all pretty close to the
existing road, and the station building is quite modest.

Not as far as I know.

Dunno, I was only commenting about EMD and Northstowe Parkway.

The Lea Bridge station is a reopening, using the existing platforms. A
better comparison might be the all-new station at Southend Airport, which
cost £16m in 2011. Allowing for inflation, the new stations for 8-car
trains might cost £20m apiece, plus a few million each to upgrade two
existing stations, so the stations probably account for ~£50m.

They are very expensive platforms then.

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.
