Eurostar has already been involved in reviewing and publishing reports into High Speed 2 for the British Government[244] and looks favourably upon such an undertaking. The operation of Regional Eurostar services will not be considered until such time as High Speed 2 has been completed.[2] Alternatively, future loans of the North of London sets to other operators would enable the trains to operate at their full speed, unlike GNER's previous loan between 2000 and 2005, where the trains were limited to 175 km/h (109 mph) on regular track.
