“The House on the Tail of the Locomotive” is a literary guide to the fairy tales of Hans Christian Andersen and an expedition to the cities of Denmark, Switzerland, Italy and Germany. Maps, photographs, stories about architecture and history, QR codes leading to galleries with illustrations and comments will help you plan an excursion, virtual or real. If you pack a backpack and follow the designated route, you can spend a day inside a fairy tale and even take away a pebble from there. Nikolai Gorbunov is the founder and chief ideologist of the literary travel project “Clutch Pedal with Reality.” Organized more than a dozen expeditions with “deep immersion” into the reality of cult books.
