1. A system comprising:
- track examination equipment configured to obtain plural track parameters indicative of a condition of a track segment of a track over which at least a first locomotive system and a second vehicle system travel, wherein the track examination equipment comprises a stationary wayside unit and a mobile track inspection unit, and the mobile track inspection unit comprises an inspection system mounted on the second vehicle system operating over the track prior to the first locomotive system;
locomotive examination equipment that is configured to generate a locomotive parameter that is indicative of an operational condition of the first locomotive system; and
a controller configured to receive the track parameters and the locomotive parameter, the controller further configured to examine the track parameters to determine the condition of the track segment prior to the first locomotive system entering the segment, andthe controller further configured to control at least one operational aspect of the first locomotive system in response to both the determined condition of the track segment and the locomotive parameter.

Abstract
A system and method for examining a route and/or vehicle system obtain a route parameter and/or a vehicle parameter from discrete examinations of the route and/or the vehicle system. The system includes a controller and route examination equipment. The route examination equipment obtains a route parameter indicative of a condition of a route over which a vehicle system travels. The controller receives the route parameter, and examines the route parameter to determine the condition of the route. The controller can control at least one operational aspect of the vehicle system in response to the determined condition of the route.

18. A system comprising:
-
track examination equipment configured to obtain plural track parameters indicative of a condition of a track segment of a track over which at least a first locomotive system and a second vehicle system travel, wherein the track examination equipment comprises a stationary wayside unit and a mobile track inspection unit, and the mobile track inspection unit comprises an inspection system mounted on the second vehicle system operating over the track prior to the first locomotive system; locomotive examination equipment that is configured to generate a locomotive parameter that is indicative of an operational condition of the first locomotive system; and a controller configured to receive the track parameters and the locomotive parameter, the controller further configured to examine the track parameters to determine the condition of the track segment prior to the first locomotive system entering the segment, and the controller further configured to control at least one operational aspect of the first locomotive system in response to both the determined condition of the track segment and the locomotive parameter, prior to the first locomotive system entering the segment, wherein the at least one operational aspect of the first locomotive system includes the track and locomotive system speed of the first locomotive system, and in a first mode the controller is operable to control the locomotive system speed over the track if the determined condition is below a determined threshold value, and in a second mode the controller is operable to control the first locomotive system to change at least a portion of the track from a first track portion to a second track portion, responsive to the first track portion having the segment that has the determined condition below the determined threshold value and the second track portion not having the segment with the determined condition. - View Dependent Claims (19)
