Abstract: A hierarchy of procedures sets pacing schedules for trains operating in a railroad network. At a train level of the hierarchy, a network coordinator sends time windows to a train indicating when the train should arrive at or depart from a siding along its track. The time windows provide flexibility for the train to adjust its pace as needed, for example, to conserve fuel. At a territory level, if the train indicates that it cannot comply with the time windows, the coordinator evaluates and adjusts pacing schedules at least for other trains sharing the same track in the territory to avoid conflicts, again providing time windows for the trains to adjust their pace as needed. At a network level, the coordinator ensures that pacing schedules adjusted for a territory also meet time windows set for trains crossing a boundary into another territory in the network.

Abstract: A train control system includes independent virtual in-train forces modeling engines onboard each of a plurality of locomotives in a train. Each of the plurality of locomotives may also include an analytics engine and a calibration engine configured to assimilate, analyze, and calibrate real time information from the locomotives and from draft gears and couplers interconnecting the locomotives and non-powered rail cars with determinations made by the independent virtual in-train forces modeling engine onboard the respective locomotive, with the plurality of locomotives of the train being configured to operate collectively and coordinate their own acceleration values based on a common goal of minimizing in-train forces without being dependent on command and control signals from a lead locomotive or central command.

Abstract: Systems and methods of generating synthetic training data for training an AI model usable to operate a train are disclosed. A method of generating the synthetic training data includes obtaining run data corresponding to a real-world run of the train. The method includes generating a physics-based simulation of the real-world run of the train. The method includes receiving a user input modifying at least one operation command of the train in the physics-based simulation. The method includes updating the physics-based simulation based on the received user input. The method includes generating the synthetic training data for training the AI model, based on the updated physics-based simulation.

Abstract: A cylinder head assembly includes a cylinder head casting, and an injector sleeve within an injector bore in the cylinder head casting. The injector sleeve includes a first sleeve end, and an injector clamping surface formed by an inner sleeve surface adjacent to a cylindrical second sleeve end. The injector sleeve further includes a sleeve clamping surface in contact with an upward facing middle deck surface of the cylinder head casting, and a reaction wall extending between the injector clamping surface and the sleeve clamping surface to transfer an injector clamping load to the upward facing middle deck surface.

Abstract: An engine power module includes a water jacket, a cylinder liner, and a cylinder head. The water jacket forms a coolant supply conduit arranged in a lower coolant annulus extending around the cylinder liner and an upper coolant annulus extending around the cylinder head. The cylinder head has formed therein an injector bore, and a plurality of drill holes convergent on the injector bore. A lower coolant cavity in the cylinder head forms a coolant flow path extending circumferentially around the injector bore between a cavity inlet opening fluidly connected to the coolant supply conduit, and a cavity connection opening fluidly connected to an upper coolant cavity. The arrangement provides flows of coolant through the drill holes to cool an injector sleeve, and separate coolant flows through the lower coolant cavity and upper coolant cavity.

Abstract: A compressor housing for a turbocharger may include an outer volute having an outer volute inner surface with a clamp groove defined therein, and an inner volute having an inner volute outer surface and an axially facing surface. The inner volute is inserted into the outer volute through the outer volute inner surface with the inner volute outer surface facing the outer volute inner surface. The inner volute is positioned with the axially facing surface disposed axially inward of the clamp groove. A clamp plate includes a radially outward portion inserted into the clamp groove and a radially inward portion extending downward past the inner volute outer surface. The clamp groove and the axially facing surface engage the clamp plate to retain the inner volute within the outer volute when an axial load is applied to the inner volute.

Abstract: A jacket cooling system for an engine of a locomotive is disclosed. The jacket cooling system may comprise a jacket coolant pump driven by a crankshaft of the engine. The jacket cooling system may further comprise a coolant jacket associated with one or more components of the engine, and a delivery conduit in fluid communication with the outlet of the jacket coolant pump and configured to deliver a coolant from the jacket coolant pump to the coolant jacket. The jacket cooling system may further comprise a bypass circuit configured to divert the coolant away from the delivery conduit and the engine, and an electronically-controlled bypass valve in the bypass circuit. The bypass valve may allow at least some of the coolant to flow through the bypass circuit when a valve position of the bypass valve is at least partially open.
