The tram only have 1 single line. Very easy, just like our Putra LRT. Please purchase GO Card in any of the 7-eleven store. You can save a lot on the fare. Go Card is just like our TNG card. Can use for bus as well. Oh, before you alight to the tram, you must touch your card at the machine located at the station and not in the Tram. On your last day, you can return it at any Tourist Info Counter/Airport and get your balance and deposit back.

Hope this helps.
