Props to Japan though, instead of wasting money with smaller projects, many of which get funding only to be cancelled or scaled back halfway through, they have the drive to actually go all the way and spend the money to do it properly. Just look at their maglev train line, tunneling entirely though a massive mountain range, 90%of the track is underground, and meanwhile us Brits are still debating weather or not to even go ahead with HS2, and the Americans have bridges failing due to lack of maintenance funding.
