High rents and a dispute with her landlord put one female student off renting so much that she decided to become 'voluntarily homeless' and live on public transport.
Leonie Müller, 23, a student at Tübingen University, Germany, has been living on trains since moving out of her flat in Stuttgart on May 1 and says she now has "no permanent accommodation" but does own a BahnCard 100 which means she can board every train in the country for free.
Müller, who has been writing about her unique living arrangements on her 'Wherever you go, there you are' blog, says since giving up her flat she now lives on trains - washing her hair in the onboard bathrooms and writing her essays while traveling at speeds of up to 190 mph.
She wrote on her blog: "The plan is simple: A year, a BahnCard 100, no permanent accommodation and me."
Describing herself as a 'digital nomad' Müller said living on trains, some of which have overnight sleeper facilities, is now costing her less than life in her previous home.
She said: "The BahnCard cost me less than my own apartment or a dorm room, the semester ticket and semi regular visits to family, friend and friends together. Much less."
