I have been well aware of what HS2 actually is since it first was announced years ago. My parents lost a massive value on their house because of it so a lot of research was done into the project.
The whole thing when you look into it is a massive con, and a lot of people are making good money out of it. Originally they were going to link it to HS1 (channel tunnel), but would have to route through Camden. They basically decided they couldn't take the residents on, so scrapped that part of the route and tried to spin it saying they were only trying to save money. Project was at about 100 Billion at the time and that part would have saved 1 Billion of that. What's the point if it doesn't link up to HS1? Again, just serving London.
Even if you go back almost 10 years, there were obviously people being paid to infiltrate forums and argue pro-hs2 Propaganda. Dodgy as fuck.
