When you live in Bratislava and dont have a car, this is a common site in your everyday life. This is an electronic tram. These, along with buses and electricka's(buses than run on gas and electric) keep the half million people in this city moving. Its about 50 cents for 10 minutes of riding, which can get you alot of places in the city or for a few cents more you can ride for 30 minutes. They are quite efficient with regard to schedule, you can usually set your clock by them. But you must be on your toes because if you are not getting on this vehicle within a few seconds of it arriving you can easily get left behind. You can almost see the slight urgency of these passengers making sure they get on board.
