To keep up with the rapid expansion, the city built various rail transit systems. One of them is the regular subway. All stations have pretty much the same design. Strange feature is that the doors/windows block access to the track, unless train is stopped in the station.

To get to other places you can also take the Sky Train. This does pretty much the same job as the subway, but reaches more neighborhoods. Riding it offers the chance to see the city better than while on the ground.

The last two pictures are from the Airport Link. This one is similar with the Sky Train, the only difference I’ve seen is that it only goes to the airport.

There is also a regular train station for inter city traffic but we didn’t use that.
