In several countries their freight trains are electric today. Trucks can be electric too, and a lot of shipping needn't run on fossil fuels although we're further off widespread commercial offerings than we are for trains or trucks which you can just buy today.

The main obstacle is aeroplanes, so that's Jet-A aka Kerosene as fuel, but even then if the numbers get nasty the airlines will kill a lot of services rather than try to pass on unaffordable prices and eat the fuel cost when there aren't enough buyers.

India has effectively electrified almost all of its rail transit. USA or other countries do not need to electrify all lines and the long tail is too long but even the major ones can bring in big benefits. No need to even get China in this equation.

Trains are one of the easiest forms of transport to electrify. Yes, the US is going to drag its heels on doing so, but the rest of the world is already moving on.

Whether we need them will be a function if they are financially sustainable. No profit, and they will close (as is the case with the Valero Benicia refinery in Northern California, shuttering April 2026). That is the linchpin to push fossil fuels to failure faster, find economically vulnerable and/or unsustainable fossil infrastructure and push it to failure (fossil supply chain death spiral). Because if no one will pay for it, it will not continue to exist, and the demand base to spread fixed costs across will only shrink into the future, pushing prices to unaffordability compared to non fossil alternatives.

Maritime shipping is targeting synfuels or ammonia. Hydrogen is not dense enough for ocean crossing voyages, too much cargo space is lost. They see the writing on the wall.
