Trains are only practical if everyone lives within 1/2 of the railroad line.

This is only true at the working end of the line, not the residential end.

How is it not true at the residential end? It is usually impractical to drive to the train station, park, and then take the train in. If you’re already driving, you can just drive to wherever you want to go.
