Systems and methods for adjusting operation of a train are disclosed. A method may include: receiving one or more infrared images of a brake line of the train; detecting one or more leaks of the brake line based on the one or more infrared images; and adjusting a brake command based on the detected one or more leaks.

A control system includes a first vehicle controller configured to be disposed onboard a first vehicle system moving along route segments and to receive a conditional movement authority that has a condition to be met before the first vehicle system can travel into a designated route segment of the route segments. The first vehicle controller is configured to communicate with a separate, second vehicle system to determine a state of the second vehicle system. The first vehicle controller is configured to determine whether the state of the second vehicle system satisfies the condition of the conditional movement authority. The first vehicle controller also is configured to permit movement of the first vehicle system into the designated route segment responsive to determining that the state of the second vehicle system satisfies the condition of the conditional movement authority.

A train control device including a control logic generation unit that uses an environmental model defined by the number of a plurality of closed sections constituting a track included in a predetermined control target region, a connection configuration of the closed sections, and the number of trains present on the track, a state of the environmental model being changed discretely according to a combination of a position of one control target train that is the train to be controlled, positions of zero or more other trains, and the presence or absence of reservation for each of the closed sections, and generates a control logic that is a logic for transitioning the state of the environmental model depending on the state of the environmental model so as to satisfy a predetermined condition, and a regeneration instruction unit that instructs the control logic generation unit to regenerate the control logic.

A method is provided for operating a railway network having a number of trains, the method comprises operating a scheduling machine that is in communication with the railway network over a data communication system, to receive time separated state data defining states of the railway network at respective times. The scheduling machine accesses a model of the railway network that is stored in an electronic data source. The model defines locations in the railway network that allows for passing of trains and paths for journeys of each of the trains. The method includes operating the scheduling machine to apply the state data to the model to determine, at each of the respective times, controls associated with each trains' path for each of the trains. The scheduling machine is operated to determine the controls by optimizing a objective function for the trains, such as minimizing total travel time of the trains, taking into account the locations in the network, positions of the trains and paths of each of the trains. The controls are transmitted, via the data communication system, to control movement of the trains, for example by operation of railway network switches (points) and signal lights, through the railway network based on the controls.

A method for operating a railroad crossing includes using an axle counter to capture measurement data for rail vehicles approaching the railroad crossing during passage of the rail vehicle. The velocity and the acceleration of the rail vehicle are calculated from the measurement data as properties of the rail vehicle by arithmetic measures. A time of closure is specified for triggering a closure of the railroad crossing as a function of the calculated properties of the rail vehicle. The velocity and the acceleration are calculated from the measurement data of the axle counter. The time of closure of the railroad crossing is specified with reference to the calculated velocity and the calculated acceleration as the rail vehicle is leaving the axle counter. An apparatus for operating a railroad crossing, a computer program product and a delivery apparatus for the computer program product are also provided.

The present invention discloses an iterative learning control (ILC) method for a multi-particle vehicle platoon driving system, and relates to the field of ILC. The method includes: firstly, discretizing a multi-particle train dynamic equation using a finite difference method to obtain a partial recurrence equation, and then transforming the partial recurrence equation into a spatially interconnected system model; secondly, transforming the spatially interconnected system model into an equivalent one-dimensional dynamic model using a lifting technology, and in order to compensate input delay, designing an ILC law based on a state observer, and thirdly, transforming a controlled object into an equivalent discrete repetitive process according to the ILC law, and converting a controller combination problem into a linear matrix inequality based on stability analysis of the repetitive process. The method is simple and easy to implement, considers structure uncertainty of the system, and has a good control performance and robustness.

In one aspect, a method of monitoring a mobile railway asset is provided including detecting a strain of a component of a mobile railway asset and gathering data associated with a vibration of the mobile railway asset. The method includes comparing the strain of the component and the data associated with the vibration of the mobile railway asset. The method includes determining a load state of the mobile railway asset based at least in part on the comparison of the strain of the component and the data associated with the vibration of the mobile railway asset.

The position of a rail vehicle that is parked on a track is monitored in a cold movement detection. A vehicle-side device of an automatic train safety system is deactivated when the vehicle is parked. Prior to the deactivation, a first positional value is determined by the automatic train safety system, and independently, a second positional value is determined by another localization system. With the vehicle-side device deactivated, the actual position of the vehicle is monitored by the other localization system. The additional positional values and/or a deviation of the actual position from a target position is transmitted to a track-side device of the train safety system. When the vehicle-side device is activated, the track-side device transmits the actual position of the vehicle to the vehicle-side device. If the vehicle has not moved, the automatic train guidance system can immediately assume the monitoring process starting from the first position

The invention relates to a method for determining a critical driving situation of at least one wheel of a rail vehicle, wherein a characteristic value of a fluctuation strength of a raw speed signal of at least one wheel is determined, and wherein, for the purpose of evaluating the driving situation, said characteristic value is compared with criteria which describe a critical driving situation. Upon detection of a critical driving situation, the method provides that an action is triggered in the rail vehicle, wherein the method is designed in such a way that it can be combined with or make use of a sensor system and processing devices as found in a modern rail vehicle.
