I would think water resistance would be worse than air resistance. But I guess the massive size of freighters allows them to still be more efficient than train

  Ships typically travel slower and have flatter terrain (which matters since regenerative braking on trains is not 100% efficient). Turns out both freight trains and cargo ships are in the same ballpark though, so efficiency probably depends more on specific route and model.
