You could calculate the cost to tunnel under one linear mile at 40 ft diameter and then realize that whatever number you got, it is the cheap part because you haven’t reinforced, drained, ventilated, or surfaced the tunnel.

This doesn’t require a discussion to figure out. You just have to mentally walk through the process and do some back of the envelope math.

It's even easier than walking through that. Just Google the costs per mile of a typical subway line extension. There's a reason subterranean rails only makes when land costs are at a premium.

Even then most subways would be better as elevated rail

That adds a huge amount of clutter to the surface, and is very noisy for anyone nearby.
