Short term vs long term. Trains will always be more energy efficient than planes. Once everything become electrified, we'll need to be smarter with what we use our energy for. Does it make sense to waste it on lifting something into the air or sailing it across metal?

But these are not really planes?

Term length matters since we have only a few decades to decarbonize. Moreover, bouyancy doesn't require energy to generate lift, so you can't make a naive "is it more efficient to sail across metal or lift into the air" comparison.
