From the 1980s onwards, many railway crossings were equipped with these small shelters.
They have no other function than to provide a roof for the officers working on the edge of the NP in case of rain. Although they do not have doors, they do have small windows that allow them to observe what is going on, especially for safety when passing through traffic.
These rather modern shelters replace the brick and cement huts that were found in many places.
Our reference contains one example, and comes in the form of a very simple 0.2 mm brass micro kit, the perfect model to take your very first steps in the brass kit.
