A few highlights

Three times a day, an ICE "Sprinter" runs in both directions and completes a one-way journey in less than four hours. Regular ICE trains take around four and a half hours to cover it. There will be up to 10,000 new ICE train seats per day between Berlin and Munich. Deutsche Bahn had to make the biggest change in its train schedules in its history: a third of all long-distance trains are affected.
