A switch point roller assist apparatus includes an elongated main support structure on which is movably mounted a rail securement clamp for releasably adjustably connecting the main support structure to a railroad rail. An elongated tie bar is adjustably mounted on the main support structure generally perpendicular to the main support structure. A roller support cage is pivotally adjustably mounted on the main support structure, the roller support cage supporting at least one roller rotatably mounted thereon, each roller mounted generally perpendicular to the main support structure. The tie bar is adjustably mounted to the main support structure such that the position of the tie bar is vertically adjustable relative to the main support structure. Finally, the roller support cage is adjustably mounted on the main support structure such that the position of the rollers is vertically adjustable relative to the main support structure.
