How would rail travel overtake and make obsolete Air Travel. It is impossible to build rail over the Atlantic Ocean. Even if you routed the rail through Newfoundland to Greenland and then to Iceland connecting with the European continental raillines in Scotland, the distance between Greenland/Iceland/Scotland is many hundreds of miles and water is kilometers deep. With our current grasp of engineering this is an impossible task.
High speed rail, in the US, is largely dominated by HyperLoop, for media and information coverage.
She would be envisioning a sealed system, with no major engineering limitations for placing underwater, if one had the money to do so.
Edit to add:
If you get bored, take a little visit to Virgin's HyperLoop page.
