Vancouver to San Francisco
California’s plan for a line from Los Angeles to San Francisco is long overdue (and will probably be long delayed), but why stop there? The entire western seaboard could be linked, all the way up through Seattle and into Vancouver.
Europe-wide stimulus package, anyone? Spain and Italy, two of Europe’s frailest economies, plus France (a not-quite-out-of-the-woods-behemoth) would certainly benefit from a new high-speed link across the northern Mediterranean coast.
London to Newquay
While the UK government is very slowly finalising plans for a high-speed link between the capital and a host of northern cities, it’s worth thinking of building a faster connection to the often ignored South West too. So long as it doesn’t take two decades to build.
Another US/Canada connection, this time heading west to east through the Great Lakes region from Chicago, through Detroit and Toronto, and ending in Montréal.
There’s nothing terribly wrong with Australia’s capital (though it can be a little dull) but the transport links between Canberra and the country’s two biggest cities are in need of a lift. It would also mean government officials could commute from somewhere more exciting.
