What passes for my brain seems to have seized up and I can't quite seem to get my 'ead around it.

G'day Tel,

Have a look at: chestofbooks.com/crafts/scientific-american/sup2/The-Westinghouse-Brake.html
or: en.wikipedia.org/wiki/Railway_air_brake
for some good explanations and a few pictures.
I couldn't find a good diagram but this picture might be of some use in trying to replicate it in miniature?

Regards,
Dave.
