The metro in Almaty is quite unique. It's brand new—opened in 2011 (though construction actually started back in Soviet times). There's just one line that runs mostly through the center, only barely touching the beginning of the residential areas.

So on weekends it's completely empty. The wait between trains is over 10 minutes (on weekdays it's 7). And even with that interval, you can usually find an empty seat.

And it's worth remembering that this is a seismically active area. That's why the metro was built to much higher safety standards. But how it would actually hold up in a major earthquake is anyone's guess. This place has experienced 10-point earthquakes back in the early 1900s.

PS. There's a metro station here called "Moscow." That's payback for the Almaty station in Moscow :)
