The reason planes are cheaper is governments subsidize them. Don’t collect proper taxes on fuel and sales taxes. Trains don’t get the same treatment. Trains are actually more effecient, physics is a real thing. It takes a ton more fuel to keep a plane in the air. The only way it’s less efficient is if you are comparing a near empty train to a full plain.
