Martin,
Since I am one of the S Scale brigade, that's probably down to me and one or two others.
There are not that many of us in total and very few actually stick their heads over the parapets in the internet forums. Myself and others, like Scott Willis, frequent Western Thunder and one or two others frequent RMWEB, although most modelling threads seem to be on here. I am actually doing a fair bit of work in S scale at the moment but it is now mostly for the parts department and probably of little interest to others - like investigating 3D printing and casting, drawing up etches for things like "W" irons, and spending half of last week making track gauges. My most recent practical modeling in the scale has been
my small US switching layout which featured over last winter. That's been done to NASG standards to match the US stock wheels and using spiked track, so probably not of much interest to you.
There's also a Yahoo email group where quite a few people pop up occasionally. It doesn't have a lot of traffic, but you normally do get responses quite promptly if you raise a thread in the group.
Yahoo! Groups
Watch out for the group name. There is a US group with the same name, but they use hyphens instead of underscores to punctuate the text.
I'm also splitting my time with a 1:32 scale layout in the garden, so whenever our summer weather allows, my modelling time is more concerned with civil engineering work in the garden.
I did have a passing thought about doing a cameo layout in S for the Wild Swan competition, but I decided that I would struggle to complete it in time so opted to consider a layout construction on an easier time frame. I've just got myself a larger car so I can now measure up to see what I can get in it. My previous car was a Citroen C1 which hardly gave room for a layout in a smaller scale.
Jim.
