A temperature abnormality detection system includes: measurement devices; and a processor to determine temperature abnormality using a first temperature T a second temperature T and a third temperature T The processor determines occurrence of temperature abnormality when any one of following conditions is satisfied: 1. A temperature abnormality detection system comprising:measurement devices each configured to measure, at a corresponding one of points on a ground through which a railroad vehicle runs sequentially, a temperature of an underfloor device of the railroad vehicle that passes the corresponding point; and{'b': 1', '2', '1', '3', '2, 'a processor configured to perform determination of temperature abnormality based on a first temperature T, a second temperature T at a point which the railroad vehicle passes after a measurement point of the first temperature T, and a third temperature T at a point which the railroad vehicle passes after a measurement point of the second temperature T, among the temperatures measured by the measurement devices,'}{'b': 0', '1', '2', '3', '4', '5', '6', '7', '8, 'wherein the processor uses threshold values A, A, A, A, A, A, A, A, and A, which are specified previously, and determines whether or not a temperature abnormality occurred when any one of following Conditions (A), (B), (C), (D), and (E) is satisfied{'b': 1', '0', '2', '0', '3', '0, '(A) (T>A) or (T>A) or (T>A);'}{'b': 1', '1', '2', '1', '4', '2', '1', '2', '2', '3', '3, '(B) (T>A) and ((T−T>A) or (T−T<0)) and (T>A) and (T>A);'}{'b': 1', '1', '2', '1', '4', '3', '3, '(C) (T>A) and (T−T>A) and (T>A);'}{'b': 1', '1', '2', '1', '4', '3', '2', '5', '3', '1', '6, '(D) (T>A) and (T−T>A) and ((T−T>A) or (T−T>A)); and'}{'b': 1', '1', '2', '1', '0', '3', '2', '7', '3', '1', '8', '1', '0', '2', '0', '3', '0, '(E) (T>A) and (T−T<) and ((T−T>A) or (T−T>A)), where A
