At the St Pancras ceremony, DB revealed that it planned to operate from London to Frankfurt and Amsterdam (two of the biggest air travel markets in Europe), with trains 'splitting & joining' in Brussels. It hoped to begin these services in 2013 using Class 407 ICE units, with three trains per day each way—morning, midday and afternoon. Initially the only calling points would be Rotterdam on the way to Amsterdam, and Cologne on the way to Frankfurt.
