Abstract:
A train control system using machine learning for development of train control strategies includes a machine learning engine (318). The machine learning engine receives training data from a data acquisition hub (312), including a plurality of first input conditions and a plurality of first response maneuvers associated with the first input conditions. The machine learning engine trains a learning system using the training data to generate a second response maneuver based on a second input condition using a learning function including at least one learning parameter. Training the learning system includes providing the training data as an input to the learning function, the learning function being configured to use the at least one learning parameter to generate an output based on the input, causing the learning function to generate the output based on the input, comparing the output to the plurality of first response maneuvers to determine a difference between the output and the plurality of first response maneuvers, and modifying the at least one learning parameter to decrease the difference responsive to the difference being greater than a threshold difference.

This type of spike is usually used in combination with a concrete tie and a guide plate that seats on the rail seat of the tie. The combination of a shaped flat bar clip which is capable of providing both rail clamping and rollover protection configurations in combination with a guide plate and spike.
Abstract:
A cooling control system (160) is provided for a mobile machine (100) having an engine (140). The cooling control system may have a circuit (210) fluidly connected to the engine, and a heat exchanger (220) configured to dissipate heat from coolant in the circuit. The cooling control system may also have a fan (230) disposed proximate the heat exchanger, a thermostat (240) configured to selectively allow coolant through the heat exchanger, and a locating device (250) configured to generate a location signal (251) indicative of a location of the mobile machine. The cooling control system may further have a pressure sensor (260) configured to generate a pressure signal (261) indicative of a barometric pressure in proximity to the mobile machine, and a controller in communication with the fan, the thermostat, the locating device, and the pressure sensor. The controller may be configured to selectively activate the fan and cause the thermostat to move to an increased cooling position when the location signal indicates the mobile machine is within a threshold area of a geological feature known to increase a temperature of the engine, and to selectively activate the fan and cause the thermostat to move based on the pressure signal when the location signal from the locating device is unavailable.

Abstract:
A train control system (100) 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 (312), a first set of output control commands from a centralized virtual system modeling engine (324), and a second set of output control commands from a distributed virtual system modeling engine (324). 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 tool for removing rail clips of the kind which are applied transversely to the rail, which includes a pair of levers connected at a pivot point and being adapted to move toward or away from each other. Each lever has at its lower end, a rail clip engagement face which engage opposed sides of a rail clip seating transversely on the rail base. Each clip engagement face inclues a clamp plate adapted to abut one side of the toes of the rail clip, an engagement pin adapted to engage one side of the rear portion of said rail clip, and a reaction pivot rear edge adapted to pivot about a point behind said rail clip. This arrangement allows the tool to be opened by moving the levers away from each other, placing the engagement faces on either side of the clip and then bringing the levers together so that the clamp plates compress the toes of the clip together so that the clip can be removed rearwardly from the rail clip support shoulder. When the toes are compressed the engagement pin abuts the rear curved portion of the rail clip and by pulling the levers away from the rail about the rear pivot base edge the rail clip is withdrawn from the base of the rail into the rail clip support shoulder.
