Abstract: 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.

Abstract: A train control device, according to one embodiment, includes a storage unit, an acquiring unit, and a control unit. The storage unit is configured to store therein information of a plurality of limit speeds corresponding to a plurality of respective blocks and being determined based on a block on which a preceding train traveling at least one ahead is located. The acquiring unit is configured to acquire schedule information of the preceding train indicating a time at which the preceding train exits each of the blocks. The control unit is configured to determine a limit speed in each of the blocks associated with a travel of a train, based on the acquired schedule information and the information of the limit speeds; and to create a travel plan of the train using the determined limit speed.
