Model railroad, simple bridge

This is a simple model of a steel bridge for model railroads. This design is based on pictures on the internet and does not model a specific bridge. I couldn't find a name for this type of bridge on the internet. Compared to a truss bridge, this design will not be very strong in the center. So it may not be a good example of a railroad bridge. I will be releasing a model of a truss bridge in a little while.

.stl files are provided for O (can be used for S), HO and N/Z. Because of the design, it should print very well and without any problems.
