1. Apparatus for determining the alignment of a wheel or a rail-supported vehicle with respect to the rail comprising a base member, means for maintaining a surface of said base member in contact with a surface of said wheel perpendicular to its axis of rotation, an elongated first bar mounted at one end to said base member for pivotal movement about an axis parallel to said surface of said base member, means for selectively fixing said first bar relative to said base member in a position perpendicular to said surface of said base member, means fixed to the opposite end of said first bar operable to indicate the angular orientation of said first bar relative to horizontal when said surface of said base member is in contact with said wheel and said first bar is in said fixed position, and first and second guide rods extending outward from said base member in position to straddle said wheel, at least one of said guide rods curving upward and outward such that contact of the rod with the rail causes the apparatus to move upward in relation to the rail when the apparatus is moved toward the rail.
