Hullo Bob,
on my original layout, I used fish-plates, copper grease and the LGB 'dog bone' joiners that clip into the sleeper ends on the curves.
When I moved to Cambridge, I had room for a much longer run of trackage, and I brought some second hand track that was fitted with clamps.
So I opted to fit the new line with rail-clamps. I've used a mixture of Massoth, Hillman and other types, and some of the sidings still use fish-plates, dog bones and copper grease! My track floats on the ballast and is not fixed, but I would do so in your case.
I've mainly used LGB track, but I have some Train-line R2 points, as well as some Piko and ART, so the clamps help with joining these makes which although Code 332, do have slight differences in the profile. Due to space constraints at the bottom of the garden, I have a return loop which is double track R1/R2, but the rest of the Main Line is R3. Most of my Rolling Stock is thus medium size, so 2-6-2 steam locos, Bo-Bo diesels and shorter bogie wagons/coaches look best to my eyes, alongside shorter 0-4-0, 0-6-0 and 2 axle vehicles.
I see that there are lots of good tried and tested tips posted on your thread, like the Coca-Cola and brown sauce ideas since I last read this thread, and I commend these to you....
