In the long run rail would be the cheapest option over self driving buses etc. Per google
Rail freight typically costs $0.03$0.05 per ton-mile, making it 34 times more affordable than trucking, which generally costs $0.15$0.20 per ton-mile. Rail is more cost-effective for long-haul, heavy freight, whereas trucks provide better speed and direct, door-to-door service
But we have to pony up the upfront expense of the new rail. And the TSA would screw up any convenience the train MIGHT offer. Plus it would be Spirit Airlines dangerous.
Rail freight is not really comparable to passenger rail. There's not a single passenger rail line in the US that makes a profit once subsidies are taken out. Most operate at a huge loss and passenger rail construction costs are staggering.
