Thanks. Is there at least some kind of super-elementary comparison?
E.g. energy consumption per-passenger-mile for a fully occupied Japanese bullet train while moving at maximum speed, versus for a fully occupied Boeing 737 at cruising altitude?
Obviously there are a million other factors, like takeoffs and landings, and trains stopping, as well as fuel vs electric, but wondering about even just the most basic operation.
