It used to be like that, even small towns had rail spurs. Socialism killed it, with the federal government paying for interstates trucking became cheaper because of course railroads have to pay to maintain their own rail.
Only the rail companies use the railroads. Everybody uses the interstate highways (except the Amish, who will when riding with somebody that has a motor vehicle capable of 45 mph or more). Even the rail companies have rail service/maintenance trucks that use the interstates.
There are a LOT more products to ship compared to the days of all the railroad spurs. There was a smaller population with a good share of them raising gardens and canning a fair amount of what they raised.
This nation will be in a world of hurt if there is ever a major breakdown of the power grid.
