They collect electricity (240volts) from overhead wires (called catenarys) through trolley poles or pantographs. The rails arn't electrified. Trust me. I'm a tram nerd.
The overhead wires are actually at a constant 600V as + and the rails act as -. Though in principle you don´t get a shock ift the tram wheels happen to be on sand, which is used to give more friction in winter, is is possible to get a 600V shock. If you ever see a tram being towed (pushed) the driver puts on 600V rubber gloves and also lowers the Pantograph.
the 600V is used for the motors and one of the breaking systems.
