A train control device includes a train position detector, a storage, and an in-vehicle controller. The train position detector detects a traveling position of a train. The storage stores therein a traveling position of the train when a loss of contact of the current collector occurs, as a loss-of-contact position. When the train travels in a predetermined section including the loss-of-contact position with reference to the traveling position of the train and the storage, the in-vehicle controller causes the train to perform coasting traveling in the predetermined section.
