Infrastructure. A train isn't just a vehicle but thousands of miles of track that must be maintained. The higher the speed, the greater the cost to build and maintain that track. Airplanes need runways, but those are a pittance to maintain compared to rail lines. Land is also 2d finite resource that must be dedicated to rail travel. Airspace is 3d. |
