It's far less at-risk if it's in a tunnel under the ground.
- jcranmer 9y agoActually, tunnels are riskier than at-grade. A fire in a tunnel is basically a deathtrap, and can even seriously impact people not inside the tunnel (see https://en.wikipedia.org/wiki/Howard_Street_Tunnel_fire https://en.wikipedia.org/wiki/Howard_Street_Tunnel_fire for an example of the latter).
