This kind of signal box, built around 1920 - 30 could be found more often
along the trackside at this time.
The architecture is just plain, but has a certain wit.

It is built with clinker stone.
Probabely the attachement was errected later and with the renovation
the yellow colour of the window frames, put some interessting accents to the front.

Be fascinated by the signal box itself and compare the Original with this model.
