Will it ever be built, do we need it.

There was a flurry of promotional videos and articles in 2011 but it seems to have gone quiet.

One journalist questioned whether a bridge might be a better and cheaper idea. 40 km of bridges in a freezing ocean that averages 150 ft deep, with god knows what currents.

What rail gauge?

Radeng, you could always change the bogies on the carriages at the borders - it's been done before I recall, between Europe and Russia amongst others.

In fact aren't coaches built these days which will automatically change gauge by moving the wheels on the axles? (presumably there would a limit but Russian gauge isn't that different).

Done in Spain on Talgo trains.

or you could use transporter wagons, as on the Leek and Manifold

Still got to decide where to put the gauge change, though. Also the overall loading gauge - I don't know how the Russian and US gauges compare. The overall loading gauge in the US is not uniform, anyway.

But like HS2, can you justify it economically?

Probably not.
It would require all new rolling stock capable of running through. The distances from POE, on both sides, to major conurbation centres is considerable and the cost of keeping the line open al year round would also be enormous.

Would you trust the maintenance or the management to run things safely?

Lon,

>Would you trust the maintenance or the management to run things safely?<
NO! Although they cannot be as bad as Notwork Rail. Back in the 1960s, the line from Swindon to Kemble was singled, limiting traffic to 4 trains per hour. After years of agonising, they shut the line for three weeks in August to turn it into double track again. So they have double track for a fair amount of the way, but because they didn't finish the job and haven't done the new signalling, it is still running as single track until they have another go next Easter....

Presumably they will electrify as part of the South Wales electrification scheme, because they need the 'Great Way Round' through Swindon and Gloucester to handle the shutting of the Severn Tunnel for engineering works. That should be fun dealing with occupation crossings......the one near me is regularly used for bringing cows across.

The Leek and Manifold and the Lynton and Barnstaple - shame both went.
They would probably run very nicely these days on tourist traffic.
