I learned about this from Railway Herald, which published the picture without attribution which makes me think that it was probably furnished by Eurostar as part of the press kit. Regular service along the 109km (68 mile) high speed line to the channel starts November 14.
The new high speed line cuts twenty minutes from the current timetable for trains between London and Paris or Brussels. Train travel to these destinations produces one tenth the CO2 of flying.
The distance from London to Paris is 213 miles (343 km) from Vancouver to Seattle 150 miles. Think you can do that in two hours (city centre to city centre) even if you flew?
What is our government doing? Widening highways.
