A robust system processor comprising three parallel processors, each configured to process in parallel an input and emit an output; and a reconciler that compares the three outputs, determines whether at least two of the outputs are equal, and if so validates the majority output and communicates the validated output via a network to at least one other system processor.

A DC-feeding-voltage calculating apparatus includes storage that stores train model information including information for controlling a regenerative power reducing amount in a train in an electrified section; feeding network model information including position information on a substation; and substation model information including control information on a substation voltage. On the basis of: the stored information; a voltage value, current values of feeders by train direction, the voltage and current values being measured in the substation; and first train information on a train including a wireless communication apparatus, an estimator estimates second train information on a train not including a wireless communication apparatus and outputs train operation information. A calculator, on the basis of the stored information and the train operation information, calculates a substation voltage setting value for controlling the substation voltage such that regenerative power is increased in a regenerative car in the electrified section.

A device for attachment to a train having a lead locomotive or control car and a rear car may include an indicator disposed with the rear car. A communication interface may receive at least one control signal from an interface onboard the lead locomotive or control car, and the control signal(s) may be generated based on at least one of an environmental condition, a hazardous condition, a type of cargo associated with the train, a time and location of the train, a positive train control (PTC), an electronic train management system (ETMS), an authorized trigger, or a manual input. A controller may be coupled to the indicator and the communication interface and may change a state of the indicator based on the control signal(s). Systems and methods for controlling an indicator are also disclosed.

A voltage estimating device for a power supply line according to one aspect of the present disclosure includes a voltage detector, a current detector, a voltage calculator. The voltage calculator calculates a magnitude of alternating primary voltage that a primary winding in a transformer receives from a power supply line based on a magnitude of tertiary voltage in the transformer detected by the voltage detector, a magnitude of output current in the transformer detected by the current detector, and correlation information. The correlation information indicates a correlation between a voltage ratio and the magnitude of the output current, and the voltage ratio represents a ratio of the magnitude of the primary voltage to the magnitude of the tertiary voltage.

Intelligent railway station platform enhancement includes acquiring contextual information informing of a context in which movement of passengers through an area of a railway station is to occur. The area includes railway station platforms spaced apart by track(s). A decision model is applied to the acquired contextual information, and a determining is made whether to temporarily bridge together platforms using a bridge component between edges of the platforms. The bridging extends across track(s) to provide a route for passengers to traverse the track(s) and move between the platforms. The temporarily bridging is then initiated if it is determined to bridge the platforms together in this manner.

A train control system comprising a track switch controller; RFID tags located at first and second track switches coupled via a length of track that store characteristics of train sets as they pass the track switches, and RFID tag readers located on the train sets, connected to a network. The train sets write data to the RFID tags such that the data is read by RFID tag readers of subsequent trains; and the data stored in the RFID tags is overwritten with new data each time a train set passes by the RFID tags.

It makes it possible to track instrument information and to obtain an accurate history of the instrument information, even when a mounting position mounted with a railway vehicle instrument has been changed. Instrument information indicating an operation or a state of a railway vehicle instrument mounted to each mounting position included in a composition is collected. A serial number determined for each mounting position is updated. The instrument information is assigned with a temporary ID including position information specifying the each mounting position and a serial number. A combination of a new temporary ID and an old temporary ID included in the temporary ID group and assigned to new instrument information and old instrument information indicating an operation or a state of a same railway vehicle instrument is estimated.

System includes a control system used to control operation of a vehicle system as the vehicle system moves along a route. The vehicle system includes a plurality of system vehicles in which adjacent system vehicles are operatively coupled such that the adjacent system vehicles are permitted to move relative to one another. The control system includes one or more processors that are configured to (a) receive operational settings of the vehicle system and (b) input the operational settings into a system model of the vehicle system to determine an observed metric of the vehicle system. The one or more processors are also configured to (c) compare the observed metric to a reference metric and (d) modify the operational settings of the vehicle system based on differences between the observed and the reference metrics.

A vehicle control system and method may include one or more processors that may receive a data set associated with plural waypoint locations along one or more routes. The data set may indicate plural waypoint locations, target arrival time windows for a vehicle system to reach the plural waypoint locations, and priority ranks of the plural waypoint locations. The processors may create and/or adjust a pacing trip plan based on the data set. The pacing trip plan may designate one or more operational settings of the vehicle system as a function of time, distance, and/or location. The pacing trip plan may be created and/or adjusted to direct the vehicle system to reach one or more of the plural waypoint locations within the corresponding target arrival time windows.

The present invention relates to a method for optimizing electric energy consumption of a plurality of vehicles connected to a same electric energy supply section. The method includes a step for determining (110) a preferred driving profile of a vehicle based on a current position of the vehicle and a destination of the vehicle, each preferred driving profile including a plurality of timeslots and for each timeslot, a desired traction value and/or a desired braking value. The method further includes steps for sending (120) of the preferred driving profile to an ATS system, acquisition (130) by an ATO system of the vehicle of an optimized driving profile generated by the ATS system, and application (140) of the optimized driving profile to the driving of the vehicle.
