VEHICLE CONTROL SYSTEM AND METHOD
A control system and method includes obtaining information associated with a vehicle system that includes one or more vehicles that are configured to move along a route. The vehicle system information is applied to a trip simulation to determine how the vehicle system is expected operate while the vehicle system moves along the route. The trip simulation includes one or more anticipated operating conditions of the vehicle system and/or anticipated route conditions the vehicle system is expected to be exposed to as the vehicle system moves along the route. It is determined whether the vehicle system will be able to stop at one or more locations along the route based on the application of the vehicle system information to the trip simulation. An alert is communicated responsive to determining that the vehicle system will be unable to stop at the one or more locations along the route.

Arrangement, test rig and method for testing a switch mechanism for changing over the path traveled by a rail vehicle on a track
A switch mechanism serves for changing over the path traveled by a rail vehicle on a track. The switch mechanism has an electric motor, the rotational movement of which is converted into a linear movement by way of a spindle rod or toothed rack. Part of the mechanical system is usually also a coupling, which prevents excessive force from being exerted on the track. A flexible adaptation for the test slider of a switch drive enables complete testing of the switch drive on a test bench. The switch drive can be tested in the final state because the test slider does not need to first be removed and then reinstalled only after testing. Separate testing of the test slider in terms of its function and its high voltage strength is therefore no longer necessary. After the testing, no additional steps need to be carried out on the switch drive.
Abnormality diagnostic device and method therefor
According to one embodiment, an abnormality diagnostic device includes processing circuitry. The processing circuitry learns, based on a model generated from sensor data of a diagnostic object in a railroad vehicle, a data selection condition for selecting the sensor data utilized to diagnose the diagnostic object. The processing circuitry diagnoses abnormality of the diagnostic object based on the sensor data satisfying the data selection condition and a diagnostic model representing a relation between the sensor data and the abnormality of the diagnostic object.
