Anyone know what it's costing Tokyo Mwtro to keep digging tunnels at very large depths? They have great coverage yet they're still digging new lines.

The issue with Tokyo is that the density supports metro expansions.
Per distance costs should be theoretically comparable? (Regulation costs and labor coming to mind as drivers of cost differences)
I was talking about the demand side / use more than the supply side / cost. But after a cursory examination of the statistics, Tokyo doesn't seem to have a measurably greater density by any common metric vs other cities.
So I suppose my above was wrong. I'd guess the more reliable enablers are only sufficient density, coupled with good geology and a cooperating regulatory / permitting structure.
