15. A system comprising:
a controller configured to:
obtain first image data of a route at a location of interest from a first optical sensor disposed onboard a vehicle system,
obtain second image data of the route at the location of interest from a second optical sensor disposed onboard the vehicle system, the second image data depicting the route at the location of interest after passage of the vehicle system over the route at the location of interest, and wherein the second image data is obtained responsive to a defined period of time expiring following the first image data being obtained, the defined period of time based on a distance between the first optical sensor and the second optical sensor and a speed at which the vehicle system is moving,
determine whether a change in the route has occurred is based on a determined difference between the location of interest in the first image data and a determined reference location that differs from the location of interest in the first image data and the second image data.
