Alan,
I don't believe it should be too difficult - I have a page from an
American book listing steam whistle tube lengths for various notes, and I
know that the bell of an A4 chime was 9" tall. According to the page, this
fits well with my daughters guess of an F# (which, on the middle octave,
requires a tube 9.1" long)
Still, I haven't tried making it yet.......

My first thought is the problem of reproducing the required notes, rather
than identifying them.
The note from an organ pipe depends mainly upon the pipe length. Even on a
loco of this size it may be hard to find the space to fit somethign of the
required size.
A resonator box is one solution which works for a single note, but I am not
sure how one would arrange it for multiple notes.

Help !
Does anyone know what chord an A4 chime whistle makes ? My musical
daughter says she can hear that the lowest note is an F# (tone deaf Dad
hasn't a clue....), but I'd like to know what the other two are so that I
can make a whistle for a large 7.25" narrow gauge engine with that
marvellous sound.....
