A wireless train control system includes: a device that generates a track circuit state signal indicating whether a track circuit is picked up or dropped and a time-triggered track circuit state signal indicating a drop at a timing delayed by a set time after the track circuit state signal indicates that the track circuit is dropped; and a controller that generates a stop limit point of a wireless-control-compliant train by using presence information if a preceding train is a wireless-control-compliant train, and generates the stop limit point by using the track circuit state signal and the time-triggered track circuit state signal if the preceding train is a non-wireless-control-compliant train. The controller does not update the stop limit point if the track circuit state signal indicates that the track circuit is dropped while the time-triggered track circuit state signal indicates that the track circuit is picked up.

A system for railway applications using beamforming transmission in a millimeter wave spectrum between antennas of a Communications Based Train Control (CBTC) system and devices in an environment. Performing a beam training with a target device of the devices located in the environment to measure beam signal values and environmental responses for different beams transmitted over the different beam angles using control circuitry connected with the antennas.

The present disclosure provides a system, an apparatus, and a method for managing operation of a rail vehicle. The method includes identifying, by a processing unit, a virtual subsystem for managing a specific operation of the vehicle based on operational data associated with the rail vehicle. The operational data includes values of parameters associated with the operation of the rail vehicle. The method further includes generating one or more operational instructions capable of managing operation of the rail vehicle using the identified virtual subsystem based on a configuration of the rail vehicle. The method further includes initiating execution of the one or more operational instructions capable of managing operation of the rail vehicle at system components located remotely from the processing unit.

A train control system uses machine learning for implementing handovers between centralized and distributed train control models. A machine learning engine receives training data from a data acquisition hub, receives a centralized train control model from a centralized virtual system modeling engine, and receives an edge-based train control model from an edge-based virtual system modeling engine. The machine learning engine trains a learning system using the training data to enable the machine learning engine to predict when a locomotive of the train will enter a geo-fence where communication between the edge-based computer processing system and the centralized computer processing system will be inhibited.

A positioning and odometry system (POS) includes one or more sensors configured to collect sensor data. The one or more sensors are operably coupled to a portable housing configured to be coupled to a vehicle body. POS has processing circuitry operably coupled to the one or more sensors. The processing circuitry is configured to determine, in response to the collected sensor data from the one or more sensors, vehicle position and odometry data.

A method of communication-based train control system migration includes scanning a guideway to generate surveying data and processing surveying data to calculate a 3-D representation of the guideway. Appropriate locations are determined for the communication-based control devices on the guideway. Communication-based train control devices are installed in a guideway at the determined appropriate locations and vehicles are retrofitted with an autonomy platform. Testing of the control devices and retrofit vehicles is performed. A communication-based train control system is used to control the retrofit vehicles when they operate within the guideway.

An automatic train operation device includes: a step command start position determining unit to determine whether a train passes through a step command start position that is a position a certain distance before a target stop position of the train; a deceleration command generating unit to generate a deceleration command to control braking force of a braking device in a section from the step command start position that the train passes through to the target stop position at which the train stops; and a travel history storage unit to store travel state information and the deceleration command for the section as a plurality of travel histories. When the step command start position is determined by the step command start position determining unit, the deceleration command generating unit generates the deceleration command by using the travel histories.

A method and system for determining a position of a rail-bound vehicle on a railway is disclosed. The apparatus comprises: a transmitter and receiver for wireless communication with at least one base station arranged at a predetermined position in the vicinity of the railway; a measurement device to determine a distance to said at least one base station based on measurements of the radio signals of said wireless communication in the time domain and/or phase domain; and a controller arranged to determine a present position of said vehicle on said railway based on said distance. A control system/method for controlling rail-bound vehicles in a railway system, and/or an internal or external system related to such rail-bound vehicles, using such position determination is also disclosed.

A rail-bound track section is equipped with an automatic train protection system. The train protection system is a combined train protection system with the functionality of a first automatic train protection system and the functionality of a second automatic train protection system. The combined train protection system takes trains equipped with the second train protection system in the track section into account during a control of trains equipped with the first train protection system, and also takes trains equipped with the first train protection system in the track section into account during a control of trains equipped with the second train protection system. A method for operating a rail-bound track section equipped with an automatic train protection system is also provided.
