It is quite cool what they have done. There system and infrastructure is quite different though because they typically build below ground and above ground. They have a pretty intricate network of below ground tunnels and shopping areas and such. Their stations are also considerably longer than most places. Their subway stations can span 3 or 4 blocks in length and I think their trains are about 3 or 4 times the length of what our 4 cars trains will be.

I also bet that these stations were servicing downtown and other high density areas, not places like crescent heights.
