Public universities are free in my third world country.

You can view the trains from the labs and classrooms.

The campus was originally, erm "train infraestructure zone" along the rails. The main building on campus are reutilized train infraestructures, for example the "Tornavías" was an old circular train garage, with the interchanger still inside.

The new buildings are constructivists
