Thanks for your info re couplings.  Interesting that a single link was used, you
say.  This is v much like the linkage talked about elsewhere suggested that I
consider - a long link with a copper tube laterally across its centre for
controlling placement - and to give it weight, I should imagine.  I'm going to
experiment with these, and what you say adds authenticity to doing so - thank
you!!!  I seem to recall way back when that Hornby's couplings were single link,
now you mention it - but I was only v little then!  ;-)

Screw couplings are used on locos and rolling stock with continuous
vacuum/air brakes; three-link couplings are used on rolling stock
without continuous brakes. Some locos that only handled un-piped stock,
such as small shunters, were also fitted with three-link couplings.

Some industrial locos even had single-link couplings, similar to those
on Hornby 'O' gauge trains!
