The article doesn't mention the downside of such broad gauge, which is the very wide bends required. It also doesn't give any particular justification for this choice.
1.) This was at the beginning of commercial mass air travel and freight transport.
Limited by range, speed, and weight for decades to come. Economics. Luxury.
Now search for the few surviving pictures of the spacious interior of the passenger wagons, and try to imagine how it would be to travel in them with 200 to 250kph.
Which was the intended speed, and already technically possible at the times. Even with normal gauge steam trains on good tracks.
2.) About the wide bends, no sleepers and ballast.
Look at any HSR > 250kph operating today. All of them are ballast- and sleeperless, so called https://en.wikipedia.org/wiki/Ballastless_track
or https://de.wikipedia.org/wiki/Feste_Fahrbahn
Sharp bends? Nope. Why? Look at how any HSR is tracked and profiled out of the inner cities, be it by tunneling, or really long bridges. Japan, France, Germany, China...
Building BIG with concrete was a thing then, just look at early 'Autobahn'. No tarmac, just big slabs of concrete. The same could be said for parts of the US at the time.
3.) BIG freight, simplifying construction of all sorts of things. Bigger prefabrication, less need for assembly on site.
F.i. https://static1.simpleflyingimages.com/wordpress/wp-content/... ,
chemical reactor(cracker tower), pressure vessel, tank, prefabedd house parts, or whole not so small houses, whatever.
They had no containers then, but imagine instead of double-stacking them like it is done now in the US, having two rows of them double-stacked.
4.) This is NOT insane. The world has been thrown back, or at least stopped in its tracks in many sectors by WWII. It only seems so, because you don't know it any different. And any big thinking is associated with Nazism. Which is ridiculous, because other nations have been building big too, then, and before.
Afterwards, not so much anymore. Because thrown back...
