Claim:
1. A railway comprising rails supported by and mounted on baseplates, wherein each baseplate is fixed to a sleeper resting on ballast, and wherein each rail is clamped to the baseplate with a clamping plate that is fitted to the baseplate with a clamping bolt, and which clamping plate has opposite extremities of which a first extremity rests on a cam provided on the baseplate and a second extremity rests on and presses the rail to the baseplate, wherein between each rail and the baseplate there is a room or space which is provided with at least two replaceable filler parts that are placed on top of each other and together exhibit a thickness in the vertical direction that matches and fills said room or space between the rail and the baseplate so as to cause that the rail can be maintained at a pre-established level, wherein the room or space between the rail and the baseplate is selectable at a predefined measure corresponding to a selectable height of the rail between a first lowest position of the rail and a second highest position of the rail, wherein in the lowest position of the rail the first extremity of the clamping plate resting on the cam is above the second extremity of the clamping plate resting on the rail, and wherein in the highest position of the rail the first extremity of the clamping plate resting on the cam is below the second extremity of the clamping plate resting on the rail so as to arrange that with variation of the height of the rail the clamping plate rotates having its center of rotation on top of the cam, and further wherein the upper surface of the cam has an upwards inclination away from the rail so as to arrange that a position where the first extremity of the clamping plate rests on the cam shifts upwards and away from the rail with variation of the height of the rail from its first lowest position to its second highest position.
