Abstract: 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.

Abstract: A method for configuring control software in a rail vehicle. The control software, which is designed for a multitude of rail vehicles, implements basic functions that are required for the basic operation of the rail vehicles. The control software additionally implements optional functions required to execute client-specific requests. The specifications, combinations and functional sequences of the basic functions and optional functions are tested, validated, and approved before the functions are implemented in the rail vehicles, whereupon the basic functions and optional functions are made available in the rail vehicles. In a selected rail vehicle, at least one optional function is activated or deactivated using a switching parameter that is individually allocated to the optional function. The switching parameter required therefor is established outside the rail vehicle and is then transmitted to the selected rail vehicle.

Abstract: A method of communication-based train control system migration includes scanning a guideway to generate surveying data and processing surveying data to calculate a 3-D representation of the guideway. Appropriate locations are determined for the communication-based control devices on the guideway. Communication-based train control devices are installed in a guideway at the determined appropriate locations and vehicles are retrofitted with an autonomy platform. Testing of the control devices and retrofit vehicles is performed. A communication-based train control system is used to control the retrofit vehicles when they operate within the guideway.

Abstract: The present disclosure provides a method and apparatus for providing an automated interlocking logic for moving-block railway signaling. According to at least one embodiment, the present disclosure provides a method for generating a train route for railway signaling based on moving block principle, including generating a directed graph for a track layout by calling pre-stored track information, generating a path matrix corresponding to the number of movement hops of a train based on the directed graph, and generating a train route from the path matrix, and verifying the train route by obtaining route information of the train from a mission of an automatic train supervision (ATS) system and comparing the route information with the train route.

Abstract: A system and method for simulating positive train control (PTC) systems in a local and controlled environment using software and hardware. The system can simulate various functionalities of the PTC system in the environment using software and hardware components. The system can instruct the software of a train management computer (TMC) to control electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing locomotive engineers and conductors to experience the PTC system for optimum training.

Abstract: The congestion degree calculation means 81 calculates a congestion degree at a vehicle and a stop. The diagram output means 82 outputs a modified diagram in which a current diagram is modified by optimizing an objective function learned using business history data including an actual change of a diagram. The risk calculation means 83 calculates a current risk which is a risk occurring at the present time, and a modification risk which is a risk caused by modifying the diagram, based on the congestion degree. The risk output means 84 outputs the calculated current risk and the modification risk.

Abstract: 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.

Abstract: A method of controlling one or more locomotives in a train includes using a machine learning engine and a virtual system modeling engine to model and classify sections of track along which the train is traveling according to the tractive power needs for the train traversing each section of track as a function of an effective weight profile for the train in the section and an effective friction profile for the train in the section of track. The method includes using the results of the effective weight profile, the effective friction profile, and an effective power availability profile to train the virtual system modeling engine using the machine learning engine to model designated areas of the track where the total tractive effort force or dynamic braking force applied by all of the locomotives in the train is less than a tractive effort force or dynamic braking force, respectively, that can be provided by a subset of the available locomotives in the train.

Abstract: A train control system minimizes in-train forces in a train with a hybrid consist including a diesel-electric locomotive and a battery electric locomotive. The train control system includes a virtual in-train forces modeling engine configured to simulate in-train forces and train operational characteristics using physics-based equations, kinematic or dynamic modeling of behavior of the train or components of the train when the train is accelerating, and inputs derived from stored historical contextual data characteristic of the train, and a virtual in-train forces model database configured to store in-train forces models. Each of the in-train forces models includes a mapping between combinations of the stored historical contextual data and corresponding simulated in-train forces and train operational characteristics that occur when the consist is changing speed. An energy management system determines an easing function of tractive effort vs. time that will minimize the in-train forces created by changes in tractive effort responsive to power notch changes in a diesel-electric locomotive, and commands execution of the easing function by a battery electric locomotive based at least in part on an in-train forces model with simulated in-train forces and train operational characteristics that fall within a predetermined acceptable range of values.

Abstract: A plurality of modules housed in a chassis is secured to the railroad tie to capture high resolution images of the underside of a train car as it passes over the plurality of cameras. These images are important to insure the structural integrity of the parts of the rail car as well as the connection means—a coupler and pin—between two rail cars. The cameras are configured to capture at a predetermined rate or to operate in sync with the velocity of the train as measured by the Linear Speed Sensor. As the images are taken, the images can be downloaded and sent to a remote location for further analysis.
