Germany

Germany's first high-speed lines ran north–south, for historical reasons, and later developed east–west after German unification. In the early 1900s, Germany became the first country to run a prototype electric train at speeds in excess of 200 km/h, and during the 1930s several steam and diesel trains achieved revenue speeds of 160 km/h in daily service. The InterCityExperimental briefly held the world speed record for a steel-wheel-on-steel-rails vehicle during the 1980s. The InterCityExpress entered revenue service in 1991 and serves purpose-built high-speed lines (Neubaustrecken), upgraded legacy lines (Ausbaustrecken), and unmodified legacy lines. Lufthansa, Germany's flag carrier, has entered into a codeshare agreement with Deutsche Bahn where ICEs run as "feeder flights" bookable with a Lufthansa flight number under the AIRail program.
