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 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 shuttle valve for a control valve coupled to an electronic fuel injector is disclosed. The shuttle valve may include a shuttle valve first end including an armature attachment portion operably coupled to an armature of the control valve and a shuttle valve second end opposite the shuttle valve first end defining a sealing portion of the control valve including an annular sealing surface. A valve guide portion may extend axially along a portion of the shuttle valve between the first and second ends. Furthermore, an engagement surface portion may be defined along the valve guide portion that is slidably engaged with a valve bore. Moreover, the shuttle valve may include a non-engagement surface portion defined along the valve guide portion, wherein the non-engagement surface is a non-continuous surface around a circumference of the valve guide portion and wherein the non-engagement surface is interspersed between portions of the engagement surface.

Abstract: Automated storage is provide for a ballast wing mounted on a regulator frame of a ballast regulator machine. A machine controller may detect actuation of a wing activation switch and, in response, actuate a wing lift cylinder connected between the regulator frame and a wing arm to dispose the wing arm within a predetermined safe zone, actuate a wing pivot cylinder to rotate a wing frame to a wing frame stored position, actuate a wing extension cylinder to retract the wing arm extension to a retracted position within the wing arm, and actuate the wing lift cylinder to rotate the ballast wing to a stored position adjacent the regulator frame.

Abstract: A train control system uses artificial intelligence for maintaining synchronization between centralized and distributed train control models. A machine learning engine receives training data from a data acquisition hub, a first set of output control commands from a centralized virtual system modeling engine, and a second set of output control commands from a distributed virtual system modeling engine. The machine learning engine compares the first set of output control commands and the second set of output control commands, and trains a learning system using the training data to enable the machine learning engine to safely mitigate any difference between the first and second sets of output control commands using a learning function including at least one learning parameter.

Abstract: A train control system enables rapid, reliable, and verifiable association of a mobile component carried by an operator with at least one of a device, feature, or short range transceiver located on one or more locomotives of one or more consists in a train. The train control system may include a mobile component configured to be carried by an operator from one of the locomotives to another in the one or more consists. The at least one of a device, feature, or short range transceiver and the mobile component may be configured to communicate with each other wirelessly when brought within a threshold distance or less from each other. The mobile component may be configured to exchange a unique identifier with each locomotive automatically or upon an action of the operator when the operator brings the mobile component to within the threshold distance or less of each of the one or more locomotives. The train control system may be configured to limit communication of wireless control commands or diagnostic information from a lead locomotive such that the commands or diagnostic information are communicated only to others of the one or more locomotives that have been verifiably identified as being associated with the lead locomotive by exchange of the unique identifier with the mobile component carried by the operator.
