Two of Western Europe's key financial cities are linked by a high-speed service, the operation of which is shared by France's TGV and Germany's InterCity Express (ICE) on a service known as Alleo. The journey is made in around four hours.
There are plans in the works for a direct high-speed service between Frankfurt and London to run in the near future. This would be operated by Deutsche Bahn, using InterCity Express trains, and would cut down the journey time between the two cities considerably, opening up the European high-speed rail network to an even greater extent.
