Warsaw (Poland) uses the bulkheads which were designed originally during the cold war era to provide an atomic shelter for the civilians. Fortunately, they weren't ever used for the original purpose, but they are now used as a prevention during the storms.

Do they close off the whole subway system?

[renw0rp]

the whole point is that they only need to shut off the stations which are at risk of flooding

PS. I think only the stations build as the first phase of the first line (planned in the '70s-'80s and finished mid '90s) have this feature.
