Abstract: An SCR after-treatment system for a locomotive engine includes an enclosure defining an exhaust flow path from an inlet to an outlet, the inlet being flexibly connected to an exhaust outlet of the engine, an injector located in the inlet and configured to provide an aerosolized reductant into the exhaust flow path, a mixing tube extending from the inlet into the enclosure towards a back wall of the enclosure; a plurality of catalyst cells extending parallel to the mixing tube; the exhaust flow path traveling through the plurality of catalyst cells between the mixing tube and the outlet, and a side channel located between the mixing tube and the plurality of catalyst cells. The enclosure is configured to create low back pressure and an even distribution of the exhaust flow path across the plurality of catalyst cells.

Abstract: A fastening system for track rail includes a molded support block, and a direct fixation fastener positioned upon an upper side of the molded support block. The direct fixation fastener includes a metallic frame and a non-metallic overmolded jacket. Clamping fasteners of the fastening system are structured to engage with retention elements integrally molded in a concrete matrix material of the molded support block to clamp the direct fixation fastener to the upper side within a range of lateral positions.

Abstract: A train control system may include a data acquisition hub connected to a database and sensors associated with one or more locomotives, systems, or components of a train and configured to acquire data in association with inputs derived from contextual data relating to a plurality of trains being operated by experienced train engineers under a variety of different conditions and in different geographical areas for use as training data. A machine learning engine of the train control system may receive the training data from the data acquisition hub, encode a modified learning function as a statistical model of desirable train handling behavior, evaluate train handling behavior by comparing to the statistical model, and update a certification of one or more of a train engineer, a semi-autonomous control system, or a fully autonomous control system.

Abstract: A train control system controls the ramp rate at which a train accelerates after braking. A machine learning engine receives training data from a data acquisition hub, including a plurality of input conditions of the train and a plurality of outputs associated with the input conditions. A virtual system modeling engine simulates 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 during operation of the train when the train is accelerating after braking, and inputs derived from stored historical contextual data related to the train. The machine learning engine trains a learning system using the training data to generate an output based on an input using a learning function including at least one learning parameter. The learning parameter is modified as needed to improve the accuracy of the learning function in generating the output.

Abstract: A machine learning system for maintaining distributed computer control systems for a train may include a data acquisition hub communicatively connected to a plurality of sensors configured to acquire real-time configuration data from one or more of the computer control systems. The machine learning system may also include an analytics server communicatively connected to the data acquisition hub. The analytics server may include a virtual system modeling engine configured to model an actual train control system comprising the distributed computer control systems, a virtual system model database configured to store one or more virtual system models of the distributed computer control systems, wherein each of the one or more virtual system models includes preset configuration settings for the distributed computer control systems, and a machine learning engine configured to monitor the real-time configuration data and the preset configuration settings. The machine learning engine may warn when there is a difference between the real-time configuration data and the preset configuration settings, the difference being indicative of at least two of the distributed computer control systems being out of synchronization by more than a threshold deviation.

Abstract: A device attached to a railcar of a train is provided. The device comprises a radio frequency (RF) transceiver to transmit and receive a RF signal. The device includes a RF modem configured to convert the received RF signal into a low frequency (LF) analog signal. The device includes a digital signal processor to process the LF signal. The digital signal processor includes a phase detector, a loop filter, and a digitally controlled oscillator. The phase detector compares the LF signal and a reference signal to generate an error signal. The phase detector also determines a state of the digital signal processor, the state being one of a lock state or an out of lock state. Further, the phase detector detects an event that the RF signal is lost and generate a loss signal. The loop filter filters the error signal and generates an error control signal. The digitally controlled oscillator generates the reference signal based on the error control signal, the state, and the loss signal.

Abstract: A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5″ of lateral support along the side of the rail base while the traditional e clip fastener provides only 3″ of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.

Abstract: A nozzle assembly for a fuel injector includes a nozzle body and a needle tip positioned within the nozzle body. The needle check includes a terminal end surface positioned in spaced, facing relation to a sac surface of the nozzle body, to form a sac cavity. The terminal end surface and sac surface each have spherical shapes, and are centered about a longitudinal axis of the nozzle body. Structures of the terminal end surface and the sac surface are such that a clearance between them is nowhere less than along a line segment between centers of the terminal end surface and the sac surface, the sac cavity has a reduced volume, and wall thickness at the nozzle tip is sufficient for improved fracture resistance.
