The main characteristics of the buildings are the "Bouniato" on the four sides, the frames of doors and windows, the false-roofs, the big wooden-bar doors, the decorating strips running across the walls of the buildings, that are all made of stone and are covered by wooden roofs of tiles. Some stations have rather peculiar architecturally-wise toilets and stone-made water reservoirs.

The railway stations of the Piraeus - Athens - Peloponnese line give some of the first examples of industrial architecture in Greece. The railway stations buildings combine functional plainness with remarkable architectural solutions and most interesting morphological elements.

By a ministerial decree of 1985, the buildings were identified as preserved monuments.
