A hub is the central part, usually cylindrical, of a wheel; the nave. It is also a point where many routes meet and traffic is distributed, dispensed or diverted. So the #HUB of Deutsche Bahn will be the place, where all ideas, connection and information will grasp together. The "#" hashtag is an integral part of the logo, referencing to social media and communication. It also can be read as a railroad track. ######
