Forget high speed trains.
As I said the future is Hyperloop. The decisions on future transport networks are going to be looking well into the future. For domestic travel/freight in 10 years aeroplanes are going to be number 1 target for carbon reduction. There's going to be a massive push for green sustainable transport not just pax but cargo as well. It's going to take time and whole lot of cash but why invest in domestic airports when you can invest in hyperloop. The pods can launch seconds apart to different destinations, no stopping at stations along the way etc and they will operate faster than commercial jets and direct down town. These things are going to have no curfews no waiting to load a full 767, freight can go 24/7 and you can have multiple city stations.
Multiple companies are investing in the tech now, flying in the future won't be cheap. It's going to get smashed by future world Governments to reduce global warming.
