Night train start-up European Sleeper wants to involve the Federal Cartel Office. It has been offering a night train connection between Berlin and Brussels for almost a year.

The company is dependent on the railway’s sales platform. Next week the company will expand its connections from Berlin towards Prague. In Belgium and the Czech Republic, his company's tickets can already be purchased on the platforms of the dominant rail providers. But despite years of discussions, the railway continues to refuse to sell competing tickets.
