Electric rail

Electric Fences are barriers of electrical energy that appear in the Mario series.

Mario Strikers series
In Super Mario Strikers and Mario Strikers Charged, Electric Fences appear around all of the soccer fields except for Thunder Island, in which they only appear at the corners. If players run into the fence, they will be shocked temporarily. The fence cannot be seen; it is transparent until players run into it.

''Super Mario Galaxy
Electric Fences appear in Super Mario Galaxy in the Flipswitch Galaxy, Sweet Sweet Galaxy, Battlerock Galaxy, Sand Spiral Galaxy, Dreadnought Galaxy, and Bubble Blast Galaxy, where they occasionally move horizontally throughout the galaxy and shock Mario and Luigi if contact is made. There are also beams of electricity in Dreadnought Galaxy that act similarly to Electric Fences. If Mario loses a life from an electric fence, he will turn into a skeleton.

''New Super Mario Bros. Wii
Electric Fences make one appearance in New Super Mario Bros. Wii. They appear in the second airship battle against Bowser Jr.. The player must knock Bowser Jr. into the fence three times in order to win. However, if Mario is pushed into the fence, he will lose his transformation until he is Small Mario. When hit in this form, he is defeated.

''Super Mario Galaxy 2
In Super Mario Galaxy 2, Electric Fences appear in the Flip-Swap Galaxy, Space Storm Galaxy, and Grandmaster Galaxy. They retain their function and effect from the previous game.

Mario Party series
In the Mario Party 8 minigame Power Trip, an eletric fence is underneath the main platform. In Mario Party 9, an Electric Fence surrounds the ring in the minigame Bumper Sparks.
