Têtes de trains is a collaboration. Since 2002, Didier Philipona makes line drawings on the train Fribourg-Neuchâtel, Fribourg-Geneva, Fribourg-Bern, Fribourg-Bienne, Fribourg-Paris, Fribourg-Zürich. He spends his time in this microcosm, drawing portraits of travelers. One day he approaches an author he knows, then another. He has avague idea that he wants to connect texts to the drawings. « We looked at the drawings, drank some coffee, thought about a way of doing it. It just snowballed. The authors, excited about the project, told me about other authors. From there the family kept growing. The project became a book.
