Interestingly, for the suburbs here in Melbourne they offered two options for grade separation: 1. Elevated rail 2. Trenches with no cover A series of campaigners in areas with higher property values wanted the trenches for “privacy” reasons and in the end many of them got them but the elevated rail receiving citizens got bike paths, basketball courts, car parks, improved walkability, generally more public space. Having experienced the two, the elevated rail is far better. The totally new line they are building though will be a TBM.
