A system includes an energy management system disposed onboard a vehicle system configured to travel on a route during a trip. The energy management system is configured to receive trip information that includes one or more constraints including at least one of speed, distance, or time restrictions for the vehicle system along the route. The energy management system is further configured to generate a trip plan for controlling movement of the vehicle system along the route during the trip. The trip plan is generated based on the one or more constraints. The trip plan has a plan speed profile that designates speeds for the vehicle system according to at least one of distance or time during the trip. The energy management system is further configured to control movement of the vehicle system during the trip according to the plan speed profile of the trip plan.

The disclosure relates to a valve assembly and a method for controlling the air suspension level of a rail vehicle. A system is provided, which is constructionally simple to build and easy to parameterise, for controlling the air suspension level of a rail vehicle. The object of the disclosure is achieved by a valve assembly for controlling the air suspension level of a rail vehicle, comprising a proportional directional valve, a sensor means for continuously detecting a distance variable representing the distance of a carriage body from a chassis or bogie of the rail vehicle, and a digital control device, wherein the control device is designed to be programmable for determining a control deviation based on the actual distance detected by the sensor means and a comparison with a predefinable target distance, and for continuously generating control variables as a linear function of the determined control deviation and the carriage body travelling speed. The object is also achieved by a method for controlling the air suspension level of a rail vehicle with a proportional directional valve, a sensor means for continuously detecting a distance variable representing the distance of the carriage body from a chassis or bogie, and a digital control device, wherein a control deviation is determined by the control device based on a comparison of the actual distances detected by the sensor means with a predefinable target distance, and a control variable is generated continuously as a linear function of the determined control deviation and the carriage body travelling speed.

A method and system are provided to obtain, with one or more processors, a speed profile of a vehicle system for a designated route traveled by the vehicle system. The designated route includes a plurality of segments, and the speed profile includes a planned segment speed for each segment. One or more planned segment speeds are identified that correspond to a point of interest, and respective priorities are assigned to the identified segment speeds based on the point of interest forming prioritized segment speeds. First discrete numeral values are displayed on a display, representing the planned segment speeds of the prioritized segments that are within a predetermined distance forward of a motion of the vehicle system. Second discrete numeral values are displayed on the display, corresponding to remaining segment speeds that are within the predetermined distance, until a predetermined threshold of discrete numeral values is reached.

A power control system for a vehicle system identifies coupler nodes in the vehicle system for travel of the vehicle system along a route. The coupler nodes represent slack states of couplers between vehicles in the vehicle system. The system also determines combined driving parameters at locations along the route where a state of the coupler nodes in the vehicle system will change within the vehicle system during the upcoming movement of the vehicle system. The system determines a restriction on operations of the vehicle system to control the coupler nodes during the upcoming movement of the vehicle system and to distribute the combined driving parameters among two or more of the vehicles.

A system that can automatically measure, track, and/or report train emissions for complying with geographic environmental restrictions. An emissions module determines the amount of emissions emitted by a train over time. A location module tracks the location of the locomotive of the train relative geographic locations having emission regulations. A compliance module records the amount of emissions emitted by the train in the geographic location.

A driving assistance device including means for determining a target speed, means for comparing an instantaneous speed of the railway vehicle with the target speed or with an interval around the target speed, and means for displaying driving instructions intended for a conductor of the railway vehicle, the driving instructions including instructions for modifying the instantaneous speed in order to bring it closer to the target speed, the display means being configured to: display a speed increase instruction icon when the instantaneous speed is below a first predetermined value, and to display a speed decrease instruction icon when the instantaneous speed is above a second predefined value.

A system for operating a train having one or more locomotive consists with each locomotive consist comprising one or more locomotives, the system including a locator element to determine a location of the train, a track characterization element to provide information about a track, a sensor for measuring an operating condition of the locomotive consist, a processor operable to receive information from the locator element, the track characterizing element, and the sensor, and an algorithm embodied within the processor having access to the information to create a trip plan that optimizes performance of the locomotive consist in accordance with one or more operational criteria for the train.

A system includes an engine and a controller. The engine is capable of multiple operating modes, and each mode has a relatively different fuel ratio such that as the engine is changed from a first operating mode having a first ratio of a first fuel to a second fuel to a second operating mode having a second ratio of the first fuel to the second fuel. The controller is operable to change the engine from one operating mode to another operating mode.

The invention relates to systems and methods that provide a higher degree of precision and a greater coordination of vehicle movement than is possible in conventional systems. A control system is designed to enforce vehicle movement along a route to a position versus time trajectory. The control system includes control equipment on the vehicle that reports its location on the track periodically. The controlling computer receives the report, and knowing where the vehicle should be and how fast it should be traveling at that point in time via a run definition table prepared for the route, calculates a position and velocity error, then calculates and sends a tractive effort adjustment command to the vehicle that attempts to reduce the position and velocity error. The invention includes a method for providing an estimated force command for a given target velocity and acceleration that can be used in the overall control methodology.
