Physics gets removed from the conversation when we start to view trains as endlessly more efficient than airplanes. They aren’t, and in the US part of that equation is the requirement to make passenger trains able to survive a full collision with a freight train, adding a great deal of weight and removing much of the physical advantage of low rolling resistance. Other examples are the overly prescriptive regulations for trains, which is a situation that the aeronautical industry has recently been able to make major gains on. Trains are great, but they’re not necessarily better for the environment or the users than airplanes because of their physics.
