The Santiago Metro

The Santiago Metro (official site) has three interesting features that distinguish it from other Metro's that I have been on:

• The train cars roll on rubber wheels.
• The 8 to 10 cars are linked together as one, you can walk from front to back through one continuous, articulated cavern.
• It is relatively quiet, the steel clanking of a traditional subway is missing.
  

This interesting looking fan was installed in some of the stations. Periodically, a spray of water comes out of some nozzles mounted to fan's metal housing.




Here is a side view from the train. The picture did not come out so well, I will try to get another one over the next few days. Notice the rubber wheels.
