A method includes determining a location of a vehicle system traveling on a track during a first trip relative to a curve in the track. The method also includes monitoring a temperature profile at a contact interface between a wheel of the vehicle system and a rail of the track that contacts the wheel as the vehicle system traverses the curve in the track. The temperature profile is based, at least in part, on a first speed profile of the vehicle system during the first trip. The method further includes analyzing the temperature profile to detect a flanging event between the wheel and the rail as the vehicle system traverses along the curve in response to the temperature profile indicating that a flange of the wheel engages a side of the rail.

1. A method comprising: determining a location of a vehicle system traveling on a track during a first trip relative to a curve in the track;monitoring a temperature profile at a contact interface between a wheel of the vehicle system and a rail of the track that contacts the wheel as the vehicle system traverses the curve according to a first speed profile of the vehicle system;analyzing the temperature profile to detect a flanging event between the wheel and the rail as the vehicle system traverses along the curve in response to the temperature profile indicating that a flange of the wheel engages a side of the rail, andwith a processor, at least one of controlling the vehicle system or directing an operator to control the vehicle system responsive to the flanging event that is detected. 2. The method of claim 1, wherein the temperature profile indicates that the flange of the wheel engages the side of the rail responsive to a characteristic of the contact interface exceeding a threshold. 3. The method of claim 2, wherein the characteristic of the contact interface is a temperature at the contact interface and the threshold is a designated temperature. 4. The method of claim 2, wherein the characteristic of the contact interface is a surface area of the contact interface and the threshold is a designated area. 5. The method of claim 2, wherein the characteristic of the contact interface is a location of the contact interface relative to at least one of the wheel or the rail, and the threshold is a designated distance relative to a lateral center of the at least one of the wheel or the rail. 6. The method of claim 1, further comprising controlling movement of the vehicle system on the track according to a second speed profile during a subsequent second trip to avoid the flanging event as the vehicle system traverses the curve in the track. 7. The method of claim 6, wherein in response to detecting the flanging event as the vehicle system traverses the curve according to the first speed profile during the first trip, the movement of the vehicle system is controlled during the subsequent second trip according to the second speed profile that is less aggressive around the curve relative to the first speed profile. 8. The method of claim 1, further comprising disregarding temperature increases in the temperature profile responsive to detecting braking efforts of the vehicle system as the vehicle system traverses the curve. 9. The method of claim 1, further comprising generating a trip plan for a subsequent second trip of the vehicle system on the track, the trip plan designating at least one of tractive efforts or braking efforts for the vehicle system such that the vehicle system traverses the curve in the track during the subsequent second trip at a speed that avoids the flanging event. 10. The method of claim 1, wherein the location of the vehicle system relative to the curve in the track is determined by comparing global positioning coordinates of the vehicle system received by a locator device on the vehicle system to global positioning coordinates of the curve in the track that are stored in a database on the vehicle system. 11. The method of claim 1, further comprising measuring an amount and direction of longitudinal force between two vehicles in the vehicle system as the vehicle system traverses the curve, the wheel being a component of one of the two vehicles, and determining whether the wheel is pulled radially inward relative to the curve or pushed radially outward relative to the curve as the vehicle system traverses the curve based on the longitudinal force. 12. A system comprising: a locator device configured to determine a location of a vehicle system traveling on a track during a first trip;a temperature sensor configured to monitor a temperature profile at a contact interface between a wheel of the vehicle system and a rail of the track that contacts the wheel as the vehicle system traverses the track; andone or more processors configured to identify when the vehicle traverses a curve in the track based on the location of the vehicle system, the one or more processors further configured to analyze the temperature profile to detect a flanging event between the wheel and the rail as the vehicle system traverses the curve at a first speed of the vehicle system in response to the temperature profile indicating that a flange of the wheel engages a side of the rail. 13. The system of claim 12, wherein the wheel has a conically-shaped running surface, the flange extending radially outward from an edge of the running surface, the wheel being configured to move laterally relative to the rail as the vehicle system travels on the track, the one or more processors configured to detect the flanging event responsive to the temperature profile indicating that both the flange and the running surface of the wheel engage the rail. 14. The system of claim 12, wherein the one or more processors are configured to analyze the temperature profile to detect the flanging event responsive to a temperature at the contact interface exceeding a designated threshold temperature. 15. The system of claim 12, wherein the one or more processors are configured to analyze the temperature profile to detect the flanging event responsive to a surface area of the contact interface exceeding a designated threshold surface area. 16. The system of claim 12, wherein the one or more processors are configured to analyze the temperature profile to detect the flanging event responsive to a location of the contact interface relative to at least one of the wheel or the rail exceeding a designated threshold distance relative to a lateral center of the at least one of the wheel or the rail. 17. The system of claim 12, further comprising a linear force sensor disposed between two vehicles of the vehicle system, the wheel being a component of one of the two vehicles, the linear force sensor configured to measure an amount and direction of longitudinal force between the two vehicles, the one or more processors configured to determine whether the wheel is pulled radially inward relative to the curve or pushed radially outward relative to the curve as the vehicle system traverses the curve based on the longitudinal force measured between the two vehicles. 18. The system of claim 12, wherein in response to detecting the flanging event as the vehicle system traverses the curve at the first speed during the first trip, the one or more processors are configured to control movement of the vehicle system during a subsequent second trip on the track such that the vehicle system traverses the curve at a different, second speed to avoid the flanging event. 19. The system of claim 12, wherein the one or more processors are further configured to generate a trip plan for a subsequent second trip of the vehicle system on the track, the trip plan designating at least one of tractive efforts or braking efforts for the vehicle system such that the vehicle system traverses the curve in the track during the second trip at a second speed that differs from the first speed. 20. The system of claim 12, wherein the locator device is configured to receive global positioning coordinates of the vehicle system, the one or more processors being configured to compare the global positioning coordinates of the vehicle system to global positioning coordinates of the curve in the track that are stored in a database on the vehicle system to calculate a proximity of the vehicle system relative to the curve in the track.
