categories in use, which differ in respect of their additional functions: Couchette car (type 248.5) Couchette car with compartment for passengers with restricted mobility (type 249.1) Combined luggage and couchette car (type 874.1) Seated cars The seated cars consist of compartment cars (six seats per compartment; type 236.9) and open-saloon cars with reclining seats (types 875.X) Operations The aim of the City Night Line network was to supplement the European long-distance network on long routes. Journey times of six hours or more were shifted to night-time slots so that passengers can sleep as they travel without losing unnecessary time. City Night Line trains were operated in a through coach system. From their joint departure station, they covered part of the route together as one train; on arrival at a certain station, they were split up and joined to other trains, with which they then continued to the different destination stations. The same procedure applied on the return journey. For example, the trains on the Amsterdam – Munich and Amsterdam - Zurich routes ran as a joint train as far as Mannheim, where the train was split up. The train section travelling to Munich was joined to a train coming from Paris with destination Munich, while the section travelling to Zurich was joined to a CNL coming from Hamburg. On the changeover to the 2009/2010 timetable, the number of these shunting processes was reduced to one per network. Last schedule The last City Night Line schedule, valid from December 2015 to December 2016, consisted of the following services: In 2014 these trains were also going: Fares and prices Germany Fares for CNL services were allocated to the IC/EC Product Category (formerly Product Category B), the second-highest in the three DB passenger transport categories. All saver fares for long-distance services and the corresponding discount options (such as BahnCard) could have also been used on City Night Line routes. The special offers for long-distance services which have meanwhile been introduced (such as the Lidl-Ticket or Tchibo-Ticket) were normally valid, but not always on all City Night Line routes. Passengers had to check the conditions of the individual offer. Tickets could have been purchased a maximum of three months before the first day of validity. Tickets for group travel can be purchased up to twelve months in advance, provided that the relevant timetable has already been published. In addition to the train ticket, passengers
