Readers' big infrastructure projects

Blue-sky thinking.

The Hebredies --- Faeros --- Iceland --- Greenland --- Labrador railway link seems ... interesting.

Built as a linked chain of floating submerged tunnels might be viable. Total transit time is given as 15 hours.

With 10 minute headways, 90 trains could be transiting in one direction at any time.

At 1,000 passengers each (about 25 railcars per train), capacity could reach 90,000 passengers/day, again, one-way. 2008 UK-US air traval was 18.1 million passenbers, or about 50,000/day.

Depending on routing, speed, and stops, total transit time might vary, though I see roughly 10 ---15 hours as being likely, say between Edinburgh, Scotland, and St. Johns, Newfoundland and Labrador. That's slower than commercial flight (about 6 hours), but should be with more room and comfort, if with a less impressive view.

There might be certain challenges in achieving this. As welll as unforseen consequences.
