Welcome to the Gnatterbox and to Gn15. You'll love it here
I've cast about for too many years looking for a scale to call "home" and Gn15 / G9 is it. Hopefully you will find the same thing.
Please post photos of anything you make, we love photos
. Also please don't be disheartened if things don't work first time, there's always room for a scrap pile somewhere in the corner of a layout (in my case an entire rail served scrap yard), learn from it and try again.
I'm looking forward to seeing what you make.
