RE:China Built 40,000km High Speed Rail in 15 years.. including40,000km / 6165km = 6.488 times across Canada.
15 years / 6.488 = 2.3 years
Imaging building a High Speed Rail from Vancover to Halifax, across the country, including all the bridges and tunnels needed, all in 2.3 years. Then do it 5 more times.
Trying to put things in Perspective that I can understand.
All just my opinion/view/thinking
