Or you could have a train that drops you off either close to your home or close to a bus station that drops off near your home. This would require a walkable city, so it’s definitely not as simple as just building tracks and bus stations. The issue is that Americans are so used to car dependent infrastructure, that when they try to imagine what public transport would be like, they think of it in the context of where they live. That’s why I think so many are opposed to the idea. It’s not an impossible task, it’s just that it’d require money and effort, so it probably won’t happen.
