Here it is. The world's strangest train. It leaves from the top of Ploutarch street in Kolonaki. Some people walk up but I think the effect is more spectacular when you go on what they call the Funicular Railway. If you have kids this is the way to go. It's like a ride at an amusement park...sort of. It costs about 2 euro each way and you can buy r/t tickets but the walk down is easy and you can choose which part of Athens you want to end up in.
