Abstract
An overlay for a elevator guide rail extends over the joints between segments to provide a seamless engagement surface for the guide rail. The overlay separates the engagement surface from the joints between adjacent segments to minimize vibration and improve the comfort of the ride. In one embodiment, an elevator includes a guide rail having a support formed from multiple segments joined end to end and an overlay encompassing a portion of the support. The overlay defines the engagement surface for the guide shoes of the elevator.
