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 vehicle control system includes a controller that communicates between a first vehicle and a second vehicle and/or a monitoring device in a vehicle system. The controller determines a communication loss and, responsive to determining the communication loss, switches to communicating via a different communication path. The controller also determines an operational restriction on movement of the vehicle system based on the communication loss that is determined, obtains a transitional plan that designates operational settings of the vehicle system at one or more different locations along a route being traveled by the vehicle system, different distances along the route being traveled by the vehicle system, and/or different times. The controller automatically changes the movement of the vehicle system according to the operational settings designated by the transitional plan to reduce the movement of the vehicle system to or below the operational restriction.

The present disclosure relates to a CPU module for processing railway signals. The CPU module includes a first input unit that receives an input signal from an external apparatus; a second input unit that receives a second input signal and a second instruction signal from a CPU checking module; a first comparison unit that compares the two input signals and outputs a resulting input signal if it is determined that the two signals are identical; a signal processing unit that converts the resulting input signal into a first instruction signal; and a second comparison unit that compares the first instruction signal with the second instruction signal and outputs a resulting instruction signal if it determines the two instruction signals are identical; and a control unit that sends a synchronization signal for controlling operation timing of the two comparison units, the signal processing unit, and the CPU checking module.

A system is provided that include at least one positioning system that can detect a location or position of a vehicle or a portion of a vehicle group that includes the vehicle, at least one sensor positioned on or associated with the vehicle that can generate sensor data of a determined parameter or condition, and a controller in communication with the sensor and the positioning system. The controller can determine that a hazard event has occurred based at least partially on sensor data, and can communicate a hazard event notification based at least in part on the location data and the sensor data to a remote server.

A RIO device mounted to a train includes an output unit that outputs a signal to a relay mounted to the train, and a controller that controls whether or not to cause the output unit to output the signal. The output unit includes a readback circuit that detects whether or not the signal is outputted from the output unit. The controller makes a signal stop request and a signal output request to the output unit before operation of the train starts, acquires a detection result of the readback circuit while each of the signal stop request and the signal output request is performed, and detects abnormality of the output unit using the detection result.

A positive train control system and method comprises a plurality of RFID devices embedded in a track way and having data representing location stored therein, and an RFID reader/detector mounted on a train for reading the location data from the embedded RFID devices. The location data is processed on the train and/or at a central facility for determining whether the train location and/or time is consistent with a train routing order. Messages, alerts and/or warnings may be generated for an alert device and/or for automated response, e.g., via a train control system.

The invention relates to a mobile network subscriber (10) for use in a cabled network (1), particularly in a collector wire network of an electric telpher, wherein the cabled network (1) has at least one first segment (S1) and at least one second segment (S2) and wherein the mobile network subscriber (10) has a first slave modem (SM1), a second slave modem (SM2), a first contact arrangement (K1) and a second contact arrangement (K2) in each case. In order to allow a change between two segments of a network in a simple and efficient manner, it is proposed that the slave modems (SM1, SM2) be provided for communication with at least one first master modem (MM1) and/or at least one second master modem (M2) via the contact arrangements (K1, K2) and the segments (S1, S2), wherein the mobile network subscriber (10) is provided for movement along the segments (S1, S2), the contact arrangements (K1, K2) of the mobile network subscriber (10) being arranged such that the change from the first segment (S1) to the second segment (S2) involves at least one of the contact arrangements (K1, K2) being connected to the first segment (S1) and at least one further contact arrangement (K1, K2) being connected to the second segment (S2).

A terminal device includes a plurality of processing devices, each of which includes: a database; a state managing unit that manages data stored in the database; a request managing unit that determines data to request from an external system and an order in which the data is to be requested from the external system based on a management state of the data in the state managing unit, a management state of data in a state managing unit of another processing device, and a type of predetermined event requiring data in a case where the predetermined event has occurred, the request managing unit being capable of requesting data from the external system on the basis of the order; and an obtainment managing unit that manages a state of obtainment of data from the external system, and a request managing unit of a predetermined processor requests data from the external system.

According to some embodiments, a railcar monitoring system for monitoring one or more conditions associated with a railcar comprises a railcar controller and one or more sensors disposed throughout the railcar and communicably coupled to the railcar controller. The railcar controller is configured to exchange data with the one or more sensors and transmit data from the one or more sensors to a remote location. An amount of data exchanged between the railcar controller and the one or more sensors is controlled based on a railcar context. The railcar context is based on a location and/or activity associated with the railcar.

Systems and methods are provided for achieving vital ultra-wideband (UWB) based train control. Train-mounted units and wayside units that incorporate at least two separate and independent radios are used to obtain independent and separate ranging measurements in trains based on communications between the train-mounted units and wayside units. The communications includes communication of ultra-wideband (UWB) based signals.
