A temperature detection system for railway applications is provided. The system may include at least one infrared (IR) sensing element configured to detect IR signals emitted by a rail or a railcar, and a controller in communication with the at least one IR sensing element. The controller may be configured to receive the IR signals from the at least one IR sensing element, extract IR data corresponding to at least one of a rail and an undercarriage of the railcar from the IR signals, and generate a characteristic thermal profile of at least one of an ambient temperature and a rail temperature based on the IR data.
