A train control system enabling a train to smoothly travel while performing handover. The system includes an on-vehicle wireless station mounted on a train following a preceding train and connected to an on-vehicle control device of the train, ground wireless base stations capable of wirelessly communicating with the on-vehicle wireless station, and a base station control device to control the base stations. The ground wireless base station is located between the ground wireless base station with which the on-vehicle wireless station is communicating and the ground wireless base station forming a communication area including a travelling permission point determined by a position of the train. The base station control device reserves radio resources of the ground wireless base stations while communicating with the ground wireless base station.

Systems and methods are provided for vehicle host interface module (vHIM) based braking solutions and use thereof in trains.

A train wireless system includes a train detecting apparatus on the ground and a controller on a train. The detecting apparatus includes a detector and a calculator. The detector detects that the train is on rails in a block. The calculator measures an on-rail time during which the detector detects the train in the block, and calculates an on-rail detecting time during which the train has been on the rails in the block. The controller includes a distance measurer, a time measurer, a recorder, and a train-length calculator. The distance measurer measures a travelling distance of the train from a beginning of the block, the time measurer measures an elapsed time since the distance measurer starts the measurement, the recorder records the elapsed time and the travelling distance, and the train-length calculator searches the recorder based on the detecting time, and calculates the train length using a selected travelling distance.

The invention relates to a device for fastening trackside modules to a rail having a base and a head. The device includes two clamps that are clamped on the base of the rail with the use of a mechanism that extends under the base of the rail. At least one of the clamps is movable. A bracket is fastened to at least one of the clamps and a trackside module is fastened next to the head of the rail. A pair of brackets is fastened with the use of fasteners to surfaces of each of the clamps. The brackets extend transversely to the longitudinal axis of the rail and at least one upwardly extending section is fastened using second fasteners to at least one of the brackets outer side surfaces. At least one trackside module is fastened to an upper end region of at least one upwardly extending section.

A method in which a base station installed in each of a plurality of sections of a route, an antenna which is connected to the base station and installed along the route, and a control device which controls all the base stations installed along the route are used includes: measuring a strength of a signal emitted from the antenna in at least one mobile body in operation; acquiring a temporary failure determination result based on the signal strength, transmitting announcement information by the control device via the base station and the antenna to which it is determined that a failure occurs when the temporary failure determination result is acquired, transmitting an answer to the control device by an arbitrary mobile body in operation and receives the announcement information, and making a final failure determination based on the answer transmitted from each mobile body in the control device.

A train position detection apparatus is configured to detect a position of a train by receiving positioning radio waves from satellites through a reception antenna. The train position detection apparatus includes: a memory that stores therein in advance a railway design standard of a railway track on which the train travels; and one or more hardware processors that detect a position of the train by self-contained navigation based on an input signal from a self-contained navigation sensor. When a result of the train position detection based on the positioning radio waves does not satisfy the railway design standard, the one or more hardware processors correct the result of the train position detection based on the positioning radio waves with a result of the position detection by self-contained navigation.

A system includes a controller, an activation device, and a communication device. The controller may control movement of a first vehicle system absent an operator input onboard the first vehicle system. The controller may control a propulsion system and a braking system of the first vehicle system. The controller may be positioned off-board the first vehicle system. The activation device may receive a status signal indicating a presence of a work marker proximate to the first vehicle system. The communication device may communicate a lockout signal from the activation device to the controller to direct the controller to prevent activation of the propulsion system and engage the braking system to prevent movement of the first vehicle system.
