Underground housing, underground businesses, etc. Would that be better for the environment + possibly save on energy costs? Also possibly safer in certain scenarios like tornadoes etc.
Potential issues that immediately come to mind are ventilation, earthquakes, and flooding. But it’s not like underground dwellings/basements/etc. aren’t a thing, so maybe those issues have been addressed in ways I’m not familiar with.
Halfing the number of platforms certainly doesn’t help either.
There’s currently a lot of support to finish building the station and keep the old station open anyway. Traffic has increased after all. But they already sold the land the railway switches of the station sit on.
