Claim Text:
1. A curved track configured to carry a conveyor and configured to indicate lateral wear, the curved track comprising: a laterally inner rail comprising a laterally innermost edge and a wear edge; a laterally outer rail comprising a laterally outermost edge; and an indicator of lateral wear of the curved track, the indicator being embedded in the laterally outer rail and being a different color than the laterally outer rail; the curved track being configured to carry the conveyor over the indicator such that a top view of the indicator is obscured when the curved track is in a first wear state; the curved track further configured such that movement of the conveyor along the curved track wears away a portion of the wear edge of the laterally inner rail such that the curved track is in a second wear state in which, compared to the position of the conveyor in the first wear state, the conveyor has laterally shifted toward the laterally innermost edge of the inner rail and laterally away from the laterally outermost edge of the outer rail, thereby revealing a portion of the indicator of lateral wear of the curved track such that the portion is visible from the top view.
