Since 1 September 2007, smoking has been prohibited in all of Deutsche Bahn's trains. Smoking areas had gradually been reduced to both cars at the very ends of the ICE 1 trainsets (cars 1 and 14). Until 30 September 2006, smoking was allowed in the Bistro area of the restaurant car. The restaurant area had always been smoke-free. Starting in late 2005, smoking in the first class cars of refurbished trains had already been limited to the three compartments of car 14.
