yeah. I was just pointing out there was a reason. I have been thinking about it in the back of my head today. How valuable is it and is it worth it. When I look at my city metro its basically a hub and spoke and what you see is that most of the spokes are around 15-20 miles out from downtown and I know they have been extended so I think closer to 15 for the original spans. Im thinking this gets to what that other lemmy user said. Having a commute where you go from the end of one spoke downtown to the end of the other would stink. Since there are multiple spokes that are mor places to live that are sorta in that magic 15-20 mile distance. Our metra is similar but goes way farther out but also has way fewer stops. So it can be farther out without being to bad. All the same those branches tend to stop once the commute from downtown is about an hour or so. Im guessing that really the circular city type thing is the way to go and likely why most are like that barring natural barriers like oceans or whatnot.
