If you need a fix, here is a sound of the 125 horn:

Mmmm, I should as a resident point out that it is spelt Edinburgh! I was
thinking that a 125 and 225 should both be made out of Lego sometime in the GNER
livery. See here for pictures:

Actually, I'm surprised at the shortage of UK models of trains. Anyway, as you
write below, back to the APT... :)

I make my judgements on the wheelset based on this photograph here:
http://www.freefoto.com/pictures/transport_rail_modern/apt/index.asp?i=1
The carriages all share their bogies, except for the power car in the middle of
the train. This and the carriages adjacent have their own individual bogies so
that the power car can be uncoupled.

Big, huge page about the APTs (both electric and turbine):

Nice picture showing bogie differences between carriages and power car:

And this one showing that tilting mechanism failing on the first and fourth
carriages:

I would say that it's a damn fine model you've (virtually) constructed there.
It captures the look of the APT really well. Main criticism is that it really
needs the power car in the middle, otherwise it's got no-where to get it's power
from!
Hope all this helps,
