An aerial view of the Serra do Mar (the hilly country at the left) and the Cubatão river valley during the early stages of the construction of the Mayrink-Santos branch. Note the impressive destruction of the Mata Atlântica ("Atlantic Forest") promoted by the works. At that time the E.F. Pilões, a decauville-like railway, run along the Cubatão river valley.
