#3Maybe we will need to take the name a bit more literally :)

#4I assume more higher up "subways" will happen sooner or later and the underground approach will be used much less.

#5I places in Asia that have monsoon weather one typically walks UP a few steps before going down into a subway station (China/Taiwan/Hong Kong/etc)- for example this MTR entrance in Hong Kong:

This is a great solution to short term small floods, but wont protect you against longer term, or waist deep+ street flooding like we saw in Henan last week.

I’ve lived in Hong Kong for close to 10 years, and I never even thought about why almost every MTR entrance has a couple of steps up, only to go back down.

#8Newer systems being built in Asia are avoiding subways/underground systems and preferring elevated systems. In fact during a major flood, the elevated railway was pretty much the only servicing transporting system in effect.

#9> Sandy had made a mockery of the largest subway system in the world
Is the New York subway really the largest subway in the world? I thought that trophy went to subways in Tokyo or Seoul.

#10I thought the walls were the major variable and relatedly how well the earth blocks water in addition to well the local presence. The cost of any street opening subway is needing some pumping as even if you have over-awnings gravity brings rainwater down and it is rare that a city large enough a subway makes sense is away from bodies of water.
