A railroad switch point roller mechanism utilized with a rail, a moveable point and a ground supported tie. The mechanism includes a roller or wheel which turns relative to a wheel axis. A wheel support is also employed and holds the wheel relative to the ground supported tie. The support connects to the moveable point, such that the lateral movement of the wheel relative to the ground supported tie takes place when the moveable point travels laterally relative to the rail. An adjustor is also included for finely determining the up or down position of the wheel relative to the tie and the wheel support.
