Add Jakarta to the long list of major cities offering rail transport between the city center and the main airport. The new line is now open, partially, with five stops; the system will add an additional 2 miles next year. Travel time is estimated at about an hour, which is about half of the time it usually takes to drive in this hyper-congested city. Trains operate every 15-30 minutes; the one-way fare is about $7.50.
