I am not sure of the tunnels being compromised, but the one thing for sure is all that debris is still sitting on top of them. So I don't envision them restoring service until the debris is removed. Just the removal process may itself do damage. Overall I don't see it being a quick restore. The Orange Line was easy since the tunnel is to the left, looking southbound, of the garage.
Going thru Haymarket SB there is a slow order in place, so I was able to see thru some of the cross tunnel access points and didn't see any damage. If there is damage my guess it would be on the WB Green Line trackage, the headhouse and what would be the original Haymarket platform.
