    `cart` - The cart on the rail.
    `y` - The rail X coordinate.
    `x` - The rail Y coordinate.

                               int z)

  Return true if this rail uses the 4th bit as a power bit. Avoid using this function when getBasicRailMetadata() can be used instead. The only reason to use this function is if you wish to change the rails metadata.

  Parameters:
    `world` - The world.
    `x` - The rail X coordinate.
    `y` - The rail Y coordinate.
    `z` - The rail Z coordinate.
