Public transport is very good with a high density. You need only one ticket for local, regional and express trains no high-speed trains, light rail systems, trams and buses in the whole North Rhine-Westphalia. You don't need to purchase another ticket when you change from local train to bus, light rail and tram.
Example: You purchased a ticket from Aachen to Wuppertal for local, regional and express trains. Whith this ticket, you can use the monorail Schwebebahn and the city buses in Wuppertal.
