To be honest, I have used bits of the station and on later layouts and try as I might, I couldn't find the little shelter.
Today, I was in luck. I found a wall! Not just any wall but a side wall. It wasn't much but it was a good template. Enough to use it to build another one.
Here it is:
It is wide enough to hold a Peco station seat for my little plastic people. If I place it here you can't look in but it will form a barrier so that people don't fall off the platform into the billabong.
A bit of grey primer and some rust streaks and it will be ready for passengers.
That's all for now.
