Train infrastructure is being removed around the world - good luck convincing people to build more.

The fact is a train turns one trip into three trips - truck to the railway station, train to another station, truck to the final destination. That often adds days to what otherwise might be a 3 hour delivery - because trains are only cheap if you send about a hundred or so trucks full of cargo on a single trip.

Only really makes sense for really long trips but more and more of those are done by ship or airplane. Trucks aren't going anywhere.
