Trains are not panacea some people here keep thinking they are. You would need to have train stops every few hundred meters changing it into some city subway or tram, interconnected with dense and fast local public transport.

I live in Switzerland, the place for trains, efficiency and its small and dense, an ideal situation right. Tons of people use trains every day, tons of people also bike for closer distances in good warmish weather but still highways are chock full and getting fuller every year. Public transport for out-of-city commuters is simply slower, often much slower.

This morning I was considering taking a motorbike to a train station that is 5km away, then 40 mins trains and 10 minute walk to work. I took the car instead for a change, I was faster despite having to cross the very center of bottlenecked and car-hostile big city (Geneva) in top rush hour. 65 mins door-to-door via public transport vs 45 in car. That's one way, meaning 40 minutes of my private life daily saved that I can spend ie with my kids and not staring in the phone or out of window.

Normally I take the motorbike if weather permits, if not I take the public bus to the train, adding additional 15 minutes each way. That sucks pretty badly. I doubt other countries have this figured out better, and not everybody can or wants to live in city centers, especially when raising small kids. We did it for 10 years, had a work commute of 5mins via escooter, but I rather have current commute and live and raise kids in small commune next to wild forest and vineyards than that.

All above is usually much worse in many parts of US.
