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.

An anti-collision system for railcars and locomotives provides a distance ranging and worker coupling protection system utilizing remote-sensing radar techniques for use with a locomotive and railcar. The anti-collision system may include an object detector device attached to a railcar or a locomotive that detects objects in a path of the railcar and the locomotive and a train display device electrically connected to the object detector device. The anti-collision system may also include an emergency action device which enables a crew member to stop the railcar or locomotive without communication to a locomotive operator when a hazard is recognized. The object detector device may include a remote sensor, a radio, and a microprocessor programmed to include data-logging to record and log all data from the anti-collision system.

A computer-implemented method comprises: receiving, at a first one of the first electronic devices, a first wireless signal transmitted by a second electronic device attached to a vehicle; transmitting, from the first electronic device, a second wireless signal, wherein the second electronic device determines a location of the vehicle along the transportation pathway according to the second wireless signal; receiving, at the first electronic device, a third wireless signal transmitted by a second electronic device, wherein the third wireless signal identifies the determined location of the vehicle; and transmitting, from the first electronic device, a fourth wireless signal, wherein the fourth wireless signal identifies the determined location of the vehicle, wherein other ones of the first electronic devices wirelessly relay fifth wireless signals along the transportation pathway, wherein the fifth wireless signals identify the determined location of the vehicle.

An insulated glass unit comprises a first tempered glass and a second tempered glass, which are disposed to face each other, a transparent OLED module provided between the first tempered glass and the second tempered glass, including a transparent OLED panel for displaying an image and a source printed circuit board (PCB) provided with a driving circuit for driving the transparent OLED panel, a spacer provided between an edge of the first tempered glass and an edge of the second tempered glass to form a space between the first tempered glass and the second tempered glass, and a cable having one end electrically connected to the source PCB and the other end exposed to the outside by passing through the spacer.

Estimating electrical parameters of a track circuit including a transmitter, a receiver, and a track section between the transmitter and receiver. The transmitter outputs, over the track section towards the receiver, a signal including a data packet part, and the signal received by the receiver is decoded to determine the data packet received. Simulated signals are generated, via a predetermined software model including parameters of the track circuit, by varying an actual value input for the model parameters, each signal generated corresponding to actual values input for the parameters. Each simulated signal is compared with the signal received at a receiver until finding a part of a simulated signal that matches a corresponding part of the signal received at a receiver. The actual parameter values corresponding to the simulated signal that match the signal received at the receiver are estimated as the actual parameters of the track circuit.

A system includes one or more processors and memory coupled to the one or more processors, storing processor-executable instructions that cause the one or processors to perform operations. The operations include, prior to a train departing from a departure location: generating, one or more train departure strategies for a segment of a trip for the train traveling on a track from the departure location where the train is stationary, displaying information associated with the segment of the track, playing a simulation of the train traveling on the track over the segment based on the one or more train departure strategies, the simulation beginning from when the train is stationary at the departure location; receiving a selection of a train departure strategy, and engaging the selected train departure strategy for operating the train from the departure location where the train is stationary.

A Head-of-Train device suitable for mounting inside a cab of a train is disclosed. The Head-of-Train device includes a memory and a processing unit communicatively coupled to the memory, wherein the processing unit is configured to execute one or more instructions in the memory to synthesize an audio message based on status associated with at least one equipment onboard the train. The Head-of Train device further includes an audio output device configured to output the audio message.

An intelligent locomotive brake control system which selects and optimizes use of dynamic, independent, and automatic brakes on the locomotive to assure intended brake power, to minimize in-train forces, minimize brake component wear, and to automate standard train brake protocol. The system may be programmed to alter an automatic brake application commanded by a train driver to omit or reduce the amount of the automatic brake application in favor of a dynamic brake application, and independent brake application, or combination thereof.

A job aid system and method determine conditions in which a vehicle system is operating or will operate during movement of the vehicle system along one or more routes. A context-sensitive action checklist is selected or generated based on one or more of the conditions. Input from the operator of the vehicle system is received in response to one or more action items in the context-sensitive action checklist that is presented to the operator. An alertness level of the operator is determined based on the input that is received from the operator. One or more alerting actions can be implemented to increase the alertness level of the operator.

A method for displaying information for a user of a vehicle by means of a projection system, which has a projection unit, a control device, a first projection field, and at least one second projection field, wherein the information is transferred from the control device to the projection unit, and wherein the projection system is switched over from a first beam path, in the case of which light beams produced by the projection unit are directed onto the first projection field, to a second beam path, in the case of which light beams produced by the projection unit are directed onto the at least one second projection field, in accordance with the current position of a seat of the user, the light beams produced by the projection unit being deflected to a field of view of the user by the at least one second projection field.
