David,?
I used S scale rail and chairs for my Dinas layout and have been a member on and off since helping to build the MRC Thame layout back in the 70s. Currently I am not a member. Back when Dinas was built it was whitemetal chairs and bullhead rail code 90. It’s now code 87 and plastic chairs which should be just as effective. I could beg a favour of a friend who is a member but first suggest we see if anyone else here is an active member. Or pay up ?25 and join. The gazette has some useful articles with some ideas that are certainly ‘lateral thinking’ when compared with mainstream 4 and 7mm modelling.?
good luck
