This is continuous welded rail, but don't forget that it's under the best class system that we have today in Canada, which is not sufficient for what is virtually high-speed rail, and with no electrification and no signals. If you look at the other side of the spectrum, Holland just built a high-speed rail network to link to Belgium. They had an environmentally sensitive and beautiful field in Holland and decided they wanted to go underground. You can imagine the challenges in going underground when you're already one metre below sea level.
