ABSTRACT OF THE DISCLOSURE An indicator mechanism for an apparatus for correcting the existing grade and horizontal alignment of railroad track in accordance with a wire reference system. The mechanism includes frame means, the position of which in use is referenced to the existing position of an adjacent section of the railroad track. Pivot means are mounted for vertical, sliding movement on the frame means and a needle indicator is mounted on the pivot means to pivot about a horizontal axis generally parallel to the rails of the railroad track. Scale means are arranged on the frame means near one end of the in- dictor to indicate in combination with the indicator the existing grade and horizontal alignment of the adjacent section with reference to the wire ref- erence system. During use of the mechanism, the position of the indicator is adjusted by a reference wire of the system which contacts the indicator. Preferably, this reference wire extends through a relatively small hole in the bottom portion of the indicator. The scale means comprises two separate scales, one scale to indicate the existing grade and the other scale to in- dicate the horizontal alignment of the adjacent section. :
