A safety system and related methods for a train are provided. Sensors are located at axles and bearing of freight cars. Where a control system determines that data received from sensors located at axles and bearings of freight cars exceed safety parameters, safety devices for the train are activated which slow or stop the train, an alert is transmitted to at least two remote devices, one associated with a railroad operator authority and one associated with a local governmental authority, and deactivation of the safety devices is electronically prevented unless and until authenticated override authorizations are received from both remote devices.

A travel management device is configured to transmit a reservation request for a block section to be reserved based on track information indicating a plurality of block sections constituting a track on which a vehicle travels and a connection relationship between the block sections, the block section to be reserved being among the block sections included in the track on which the vehicle travels. A resource management device is configured to record the block section to be reserved indicated by the reservation request as a reserved block section of the vehicle which has transmitted the reservation request in case where the block section to be reserved indicated by the reservation request is not reserved by a vehicle other than the vehicle which has transmitted the reservation request at a time at which the reservation request is received.

A locomotive decision support architecture and control system interface aggregating multiple disparate datasets. Locomotive operators suffer from extremely high stress levels due to the tremendous responsibilities of their jobs. They are responsible not only for safely delivering cargo along with rolling stock, but also for the safety of the populations and the environment they travel through, all while trying to maintain a schedule and maximize profits for the company. The systems, methods, and apparatus is designed to provide an enhanced visibility of the operating environment and decision support tools to enable the operator to react to emergent conditions.

A running curve creation device of an embodiment is a running curve creation device to create a running curve which can make a train having a prescribed vehicle characteristic run between a prescribed departure station and a prescribed arrival station in a prescribed running time with a smaller cumulative energy consumption. A shortest time running curve creation unit creates a shortest time running curve in which the train runs between the stations in a shortest time, based on predetermined vehicle information and ground information of the train, and an energy saving running curve creation unit selects from the shortest time running curve and a plurality of solution candidates corresponding to states of the train at each prescribed elapsed time since the train has departed from the departure station, a solution candidate having the relatively small cumulative energy consumption in the prescribed running time, and creates an energy saving running curve based on the selected solution candidate.

System having one or more processors that are configured to (a) generate, as a vehicle system moves along a route, a plurality of different trial plans for an upcoming segment of the route. The trial plans include potential operational settings of the vehicle system along the route. The one or more processors that are configured to (b) select one of the trial plans as a selected plan or generate the selected plan based on one or more of the trial plans. The selected plan is configured to improve one or more system-handling metrics as the vehicle system moves along the upcoming segment of the route. The one or more processors are configured to (c) communicate instructions to change or not change at least one of the operational settings of the vehicle system based on the selected plan.

According to various aspects, exemplary embodiments are disclosed of devices, systems, and methods related to tracking location of operator control units for locomotives. In an exemplary embodiment, an operator control unit includes a user interface configured to receive one or more commands from an operator for controlling a locomotive. The operator control unit also includes receiver configured to receive location information of the operator control unit, and a wireless communication device. The wireless communication device is configured to transmit command data corresponding to the one or more commands and location data corresponding to the location information to a machine control unit on the locomotive.

Disclosed is method including receiving digital vessel data for a global fleet of vessels, the digital vessel data being one or more of AIS data, image data or radar data and combining one or more of pieces of data. The method includes inferring, based on the first combined data, a loaded/empty status of a vessel or a cargo. The method includes combining other data to yield second combined data, receiving data regarding one or more of supply, demand, and amount of available cargo to yield third combined data, generating information relating to a supply of vessels available to load at a specified port and/or deliver a cargo to a specified port, in each case within a specified period of time and generating suggestions for one or more vessels regarding future routes based on the data.

A method operates a rail vehicle along a railway line. Accordingly, a trip of the rail vehicle has a travel section along the railway line, which travel section ends before or at a hazard point of the railway line. The rail vehicle, in a protection mode, is braked starting from a first speed during a braking phase at the start of the travel section. During the braking phase, a kinetic quantity of the kinetic energy amount of the rail vehicle is absorbed by an energy absorption unit. The braking phase is followed by an energy dissipation phase, in which part of the absorbed energy is discharged. The travel section is defined such that an energy state parameter representative of a vehicle energy amount, which energy state parameter takes into account the energy amount present in the energy absorption unit, satisfies a condition at the hazard point.

This system includes a ground ATC and an on board ATC, which is switched from an active mode toward a standby mode and vice versa by a wake-up unit. In the standby mode, only the following components remain powered: odometry device; a main computer; a radio communication device between the on board ATC and the ground ATC; the wake-up unit. The main computer is programmed so as, in the standby mode, to verify that the movement of the train measured by the odometry device from the switching from the active mode to the standby mode is zero and, in the affirmative, to send the ground ATC an instantaneous position of the train using the radio communication device.

Methods and systems for controlling a train movement to a stop at a stopping position between a first position and a second position. Determining constraints of a velocity of the train with respect to a train position forming a feasible region (FR) for a state of the train during the movement, such that a lower curve bounding the FR has a zero velocity only at the first position, and an upper curve bounding the FR has a zero velocity only at the second position. Determining a control invariant subset (CIS) of the FR, wherein for each state within the CIS there is at least one control action having a value selected from a finite set of values that maintains the state of the train within the CIS. Controlling train movement subject to constraints by selecting a control action maintaining the state of the train within the CIS of the FR.
