There is only ONE tram line in Istanbul. The final stops are Kabatas on the Beyoglu side and Zeytinburnu on this side of the Golden Horn. Since it took a bit of trial and error for us two dolts to figure out exactly how to get the jetons (tokens) out of the automatic machines, we thought this video would be of interest.

The fare is 1.50 Turkish Lira no matter how fare you ride on the tram.
