Transportation in Tunisia’s capital has grown dramatically in the last few years, as has been the case in so many major cities around the globe. In its metropolitan area of two million, it is now so densely populated that commuters are spending a good half an hour in traffic every day. This is time, unproductive time, is frustrating for everyone involved and hurts the environment. Those responsible within the metropolis have therefore now taken to expanding the local public transit system, one step at a time, one train at a time.
