Try doing tight curves on a railroad. Try steep grades on a railroad. Try running a line to every neighborhood, with using eniment domain.
Somethings are just not practical
Rail is fundamentally superior to roads + cars at an engineering level.
All at the same time:
Rail has a smaller footprint
Rail moves multiple times more people or cargo per hour
Rail has multiple times more fuel efficiency
The fact that USA's policy has been designed to favor cars only makes them more 'practical' than rail if you consider political constraints more binding than physics constraints.
I'll grant that trucks have tighter turning radii and maximum operating grade. If we truly only used them when those characteristics are needed THAT would be 'practical'
... Rail is quite adaptive.
Here are two methods for steep inclines.
