A train speed control system 100 comprises a first contactless sensor 110 that outputs measured first speed information, a first safety device 120 that receives the first speed information from the first contactless sensor 110, a second contactless sensor 140 that outputs measured second speed information, and a second safety device 150 that receives the second speed information from the second contactless sensor 140 and transmits the second speed information to the first safety device 120 at a predetermined timing. Additionally, in the case of receiving first second speed information from the second safety device 150, the first safety device 120 evaluates the soundness of the first speed information on the basis of a speed difference between the first second speed information and first first speed information measured by the first contactless sensor 110 at substantially the same timing as the first second speed information, and determines a control speed of a train 1 on the basis of the result of the evaluation.
