You'll no doubt find some useful information in:
a) Chapter 7 of the IRSE large Green book: Railway Signalling ISBN 0713620676
b) IRSE little green book series no. 9 Track Circuits- Challis (think now re-published in a group of 4)
However don't get your hopes up too high as I doubt if either will give you as much as you want. I think your best chance may be trying a trawl of IRSE Proceedings to see what might exist from the 1980s or 1990s, although I cannot say I remember anything specific. Otherwise I think I'd try Dave Bradley who used to be known by the nickname Mr Ballaaarst Resistance".
