Received again some metal plates to seperate gravel from dirt. So I knocked them vertical into the dirt, shaveled out the earth in between, put a liner below and put the first layer of gravel above.

I temporarlely layed the joint above in order to see, if the markers are placed in the right position.

It still looks like a huge construction set, but as soon as the tracks are layed and some plants are set, it will look awesome. At least in my mind already…
