Trains are just really expensive, sadly. Trains are subsidised in most places, either by publicly funding the huge amounts of infrastructure required, or by subsidising the operations. Meanwhile air travel is usually taxed overall. Yet despite this, flying is often less than half the cost of a train. I'm all for taxing air travel CO2, but I suspect it would lead to quicker zero carbon fuel rather than more rail travel long term.
