Well, well. I used to live in Brighton, and reckon I must have covered pretty much the same ground, walking the old railways. For some time our house fire was fuelled from a huge pile of coal that was left in the coal yard at Isfield Station (Lavender's yard.) I too have scrambled down and up the Dyke Steep Grade Railway, and found the concrete supports for the Cableway. Also followed most of the Dyke branch up from Aldrington. I got a bit lost following the Polgate to Eridge line, it all got a bit overgrown with Gorse (ouch) Nort of Heathfield Tunnel! I will have to read the rest of your descriptions!
