The facility as a whole, rather than just the building, is shown here in order to illustrate the whole picture, because the rediscovered railway, as suggested in the introduction to this section, also comprises a number of activities which time has made obsolete, but which fulfilled functions of vital importance for the railway in their lifetime. In this sense, the tracks on the lake were essential for goods traffic, a vital source of sustenance for the income of the railways, in their own dimension, which today appears rather picturesque: lake/railway transhipment, a useful way of crossing distances that could not be spanned in any other way at the time… best exemplified by the last, very rare photographs of the single track..."on the sea", ascribable to the history of the company's railway.
