Culvert: A Prototype Inspiration

The Marschacht-Layout has a small stream on the left that is crossed by the tracks. Thus I need a culvert. There is a railroad line in my village, that has been shut down several years ago. Several small drainage canals cross the old railroad line. I found an interesting culvert a few hundred metres out of the town.

It has been built using a combination of rock and concrete. The railroad line has been built in the beginning of the 19th century. So I guess this culvert has also been built at that time. The basic form is not to complex and might be built by a beginner like me. So I will give it a try.
