Okay, due to some of the useful critiques made of the Giant Landship idea, I've decided to modify it into a Giant Sled idea, that gets pulled by a long tow-line extending to it from a winch located many miles ahead in the distance.
It's still going to be giant and the size of an ocean-liner, but instead
of rolling, it's going to slide across the ice. It would be used to travel across the thick ice in the Arctic/Antarctic regions.
The largely flat-bottomed hull would be made of ultra-hard ceramic for maximum hardness & abrasion resistance.
The front-bottom of the hull would have a gradual gradient to enable our giant sled to gradually surmount any frontal obstacles, snow drifts, etc and squash these down under its weight.
The entire sled platform will be pulled from the front by a cable extending to it from a Winch Station dozens of miles away. There will actually be multiple such Winch Stations which our giant Polar Liner sled will travel to, as a series of stops along its journey.
While being constructed of lightweight materials (carbon composites, foamed alloy components, etc) the sheer size of our Polar Liner means that it will unavoidably be very heavy. Therefore as it travels across the frozen wasteland, it will automatically be compacting the ground below it, creating a broad flat superhighway channel in its wake. Other smaller accompanying sled vehicles will also be traveling in that wake, like a caravan.
Repeated voyages can be made back and forth across the same routes, thus further compacting and solidifying these routes over time, especially with further snowfalls, etc.
In this way, a giant frozen-canal/superhighway network system can be built across the Antarctic for heavy freight transportation.
