In democracies sometimes it is cheaper to go underground with a number of modern multi modal TBM working 24/7 than have expensive court cases. A single 11 psi Maglev tunnel can increase speed from 600 km/h to 700km/h while still being breathable and passing stations would allow daytime trains to stop where needed with overnight container trains beating any truck by eight hours over 1,000 kilometres between freight sidings eliminating daytime planes and reducing trucks. Using Sydney to Melbourne as an example with passing stations at Canberra and Albury it would cost $60,000,000,000 and return $20,000,000 per night which makes it able to subsidise daytime fares below planes and still have a return of 10% Perhaps cooperation between Japan, China and America can develop the maglev container train with Australia to use an international guideway to benefit the world.
felix wuytens 2 months ago That was an idea for a room temperature superconducter, hasn't been proven yet . I was taught that superconductor was only at absolute zero, not room temperature.
