Tell me you don't understand how rail network work without telling me you don't understand how rail networks work.
Preface: I don't like this architecture. I think things need to change. I'm just describing what is . These are people coming from several dozen square miles and dispersing into several dozen square miles, flowing through these chokepoints. They're commuting 40, 50, or more miles. You'd need these people to change several bus lines and several train lines. Those busses would be snaking through messy suburbs for them…
I do understand the problem in the way the infrastructure is build in the area and that it isn't easy to just change and go to trains, that's not what I was suggesting.
I was specifically responding too:
"Assuming every single commuter is coming from and going to the same place, sure."
And that if of course nonsense. The whole point of a network is that you can route from one place to another. I didn't propose a whole new transport plan for the whole area. And I am not pretending that within 1 year you can change all of Texas infrastructure. I was simply pointing out a fundamentally flawed argument.
> But this is also kind of a best case of someone taking the train versus driving.
Well, this is the best case in particular situation you are describing where that kind of infrastructure has been under-invested in for 100+ years. Its not the best case for public transit.
It should NEVER take 30 min to swap from one train to another. In all of Switzerland you 90% of all connections are 10min or less. That's for the whole country including buses. If the train infrastructure was more modern and electric, trains could likely be faster. If the buses had their own lanes (not like Texas doesn't have enough lanes) the avg speed of the bus could likely be improved quite a lot.
This is just about infrastructure choices, apparently Texas can build tons of super complex incredibly expensive highway interchanges but an electric train that leaves every 15min is apparently impossible.
DoT in Texas is still on that 1960 highway building mania and is still destroying black neighborhoods so that subburban wight people can get to their office jobs at the oil company or whatever. The first step is recognizing the problem, and they are still working on that.
The whole area seems like its pretty dense with a lot of people, I don't see why it couldn't have good transit. Even just with buses on existing roads. As long as you make some room for them and give them the appropriate priority and so on. A lot could be done for not that much money, if people actually wanted.
On of the biggest problem in the US is that your tax system if fundamentally unfair and massively subsidizes suburbia. That's arguable one of the most important things that need to change. I strongly suggest looking at the work done by Urban3 and Strong Towns.
