What does train gang have to say about this? Seems like vents take a large amount of surface area which defeats the point of a subway in the long term. Would the other things he mentions in the video work?
From the video it seems that the issue has to do with the material the tunnels are surrounded by. But yeah surface railways are the easiest to deal with from an engineering perspective.
This is why I advocate for tearing down all city roads and replacing them with train tracks.
Aren't a lot of cities built on similar clay, though? From the video, he says it's a great material because it is soft enough to crave through but hard enough to support the weight of buildings.
I will not be satisfied until I see 4 way intersections for trains in the middle of cities.
I'm not too knowledgeable about what cities are built on top of so I can't really comment there, but yeah at this point the best you can do is work around the environment.
Every intersection will be like that one in the Chicago L
