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.

In one embodiment, a method includes receiving, by a controller, one or more signals from the one or more pressure transducers. The one or more pressure transducers are coupled to one or more pressure lines, the one or more pressure lines are coupled to one or more probes, and the one or more probes coupled to a vehicle. The method also includes converting, by the controller, the one or more signals to one or more digital signals.

A non-stop train system including a plurality of train cars in communication with one another and in communication with an electronic control module. The train system includes a track or any number of parallel tracks having a plurality of drop off and pick up locations. A prepositioned train car is stopped at one of the drop off and pick up locations. A non-stop express train approaches and passes by the drop off and pick up location on the track initiating the prepositioned train car to begin departure. The electronic control module is used to adjust the speed of the non-stop express train and the prepositioned train car based on a detected distance such that a rear coupler of the non-stop express train couples to the front coupler of the prepositioned train car while moving along the track.

A method for displaying secondary signal devices for a driver of a railway vehicle during a journey by a railway vehicle. From a current vehicle position of the railway vehicle and an already known signal position of a secondary signal device, an actual distance of the railway vehicle in relation to the secondary signal device is determined. In the case that the actual distance is not reached in respect of a predefined current warning distance of the railway vehicle relative to the secondary signal device, a proximity of the railway vehicle relative to the secondary signal device is displayed to the driver.

A system and method for detecting the operational status of a brake system on a railcar. The system receives from a sensor an indication of the magnitude of a braking force applied by the braking system in response to an instruction to increase or decrease the braking force. It compares the response to possible responses of the braking system in view of the instruction provided. Based on the comparison, the system generates at least one of a message and/or an alert indicating the status of the brake system. Additional sensors, including a pressure sensor on a brake pipe of the railcar, can be added for additional functionality.

A method for operating a rail vehicle includes transmitting an identifier for a software component and/or an identifier for a hardware component of a control system of a rail vehicle. The identifier is transmitted from a computation unit of the rail vehicle to a stationary central computation unit, at least at one predetermined point in time.

A display device includes a drawing processing unit displaying a status of a device mounted on a train car, and a data collection unit including a signal definition holding unit holding signal definitions to be bases of first signals requesting information on the status of the device, a signal mapping management unit acquiring configuration information on the number of cars and a traveling direction, and generating the first signals, based on the signal definitions and configuration information to request information on the device status, a signal data storage unit holding a value of a second signal as information on the device status acquired by the signal mapping management unit's request, and a signal mapping generation unit generating signal mapping information for specifying the order of the cars on a display screen, based on the configuration information, and outputting the signal mapping information to the signal data storage unit.
