Penang Hill's current funicular train is the 4th generation system which started its operation on 24th April 2011. The journey used to take about half an hour and the train may stop at intermediate stations upon request. However, upgrades to the system now allow non-stop rides to the top in five to ten minutes. The funicular track stretches a distance of 1,996 meters from lower to upper station which is the longest in Asia. Penang Hill funicular tunnel, at 79 meters long and 3 meters wide with a steepness of 27.9 degrees, is the steepest tunnel track in the world.
