Woodie, we have a railroad crossing just like this, one except the road is paved, that we cross when we go to visit my daughter and her family. I have seen trains running but not often. Most drivers zip across without even looking. Scary stuff.
In your trestle pictures, is that a bluegum tree I see? We don't get any of those here.
That Moulimein look like they could be a good scratchbuilding project.
Yep... Blue gums, Red gums, Ghost gums etc.. All bush vegetation in Australia is eucalypt. As a point of trivia, there are no native deciduous trees in Australia. Per haps I could attempt a scatchbuild, however I don't think there would be much room left on my layout if I built one of those!!
