Embodiments of the present invention are directed to improved designs of railroad spikes and improved methods of manufacturing the same. According to one exemplary embodiment, a method for manufacturing a railroad spike may comprise the steps of: preparing a metal blank having a substantially circular cross-section; subjecting the metal blank to at least one cold heading process and at least one cold extrusion process to form a railroad spike having (a) a circular head with a fillet at its bottom side that is angled to engage a railroad tie plate or rail base and (b) a non-threaded shank with a substantially square cross-section and a chiseled tip; and coating the railroad spike with an anti-corrosion material.

A system and method for testing and maintaining a power assembly of a locomotive diesel engine. In one embodiment of the invention, the testing apparatus comprises: a first test position for securing a strongback of a power assembly; a second test position for securing a cylinder head of the power assembly; and a third test position for securing a cylinder liner. In another embodiment of the invention, the testing method comprises: securing a power assembly to a first test position; removing a cylinder head from the power assembly; securing the cylinder head to a second test position; removing a cylinder liner from the strongback assembly; placing the cylinder liner into the third test position; cleaning the cylinder liner; testing the cylinder head for possible leakage; and re-assembling the power assembly cylinder head passes the leakage tests.

Embodiments of a tool and method for removing sweeper bristles from a railway track broom are disclosed. An exemplary tool may include a tube member for insertion into a sweeper bristle gripped onto a nipple element, wherein two or more slits split a front portion of the tube member into flexible prongs each having outward-facing gripping elements near its tip. A plunger element, located inside the tube member, can be propelled forward into a front end of the tube member to cause the flexible prongs to substantially expand at least part of the front portion of the tube member, thereby loosening the sweeper bristles grip on the nipple element. A hydraulic assembly coupling the plunger element to a hydraulic pressure source is controlled by a trigger mechanism to supply hydraulic pressure to propel the plunger element.

A system and method for determining rail terminal capacity needs. In one embodiment, terminal railcar inventory is determined periodically throughout a specific time interval based on terminal traffic data. Train traffic data is accessed and indexed into discrete time periods, such as daily and hourly intervals. Dwell occupancy indexes are created with periodic intervals, and assigned dwell occupancy values based on said dwell occupancy definitions and traffic data. The railcar inventory of the train terminal at any particular time may then be determined by cross-tabulating the occupancy dwell values, and applying business rules. The number and size of tracks needed to accommodate a rail terminal may be determined by assigning blocks of railcars to terminal tracks. Using the railcar inventory, a list of railcar blocks, railcar block sizes, railcar block classifications, and track classifications is created. After specifying switch parameters, the list of railcar blocks is evaluated based on the list of railcar block sizes and the list of railcar block classifications. The list of railcar blocks is then assigned to the terminal tracks, based on the list of railcar block classifications, the list of track classifications, and the switching parameters. After assigning the blocks to tracks, a final list of tracks that have been assigned blocks is generated.

Embodiments of systems and methods for bypassing an aftercooler are disclosed. According to one embodiment, the bypass valve system may include a turbocharger, an air temperature sensor, an aftercooler, a three-way bypass valve, an aftercooler conduit, a bypass conduit, a pipe fitting, an engine, a radiator, an expansion tank, a pump, a bypass control system and a locomotive control system. The temperature of the charge air is measured and sent to the bypass control system. The locomotive control system sends engine throttle conditions, such as engine notch position, to bypass control system. Bypass control system determines whether to circulate coolant through the aftercooler or bypass the aftercooler based on the temperature measurements and the engine throttle conditions. Bypass control system then sends a signal to the bypass valve to either to circulate coolant through the aftercooler or bypass the aftercooler through the conduit.
