Publication number: 20140236957Abstract: 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.Type: ApplicationFiled: February 15, 2013Publication date: August 21, 2014Applicant: Norfolk Southern CorporationInventor: Stefano Rieppi

Patent number: 8640629Abstract: Designs for a battery-powered, all-electric locomotive and related locomotive and train configurations are provided. In one particular exemplary embodiment, a locomotive may be driven by a plurality of traction motors powered exclusively by a battery assembly which preferably comprises rechargeable batteries or other energy storage means. The locomotive carries no internal combustion engine on board and receives no power during operation from any power source external to the locomotive. A battery management system monitors and equalizes the batteries to maintain a desired state of charge (SOC) and depth of discharge (DOD) for each battery. A brake system may be configured to prioritize a regenerative braking mechanism over an air braking mechanism so that substantial brake energy can be recovered to recharge the battery assembly. Many locomotive or train configurations involving battery-powered or battery-toting locomotive(s) may be implemented.Type: GrantFiled: December 31, 2012Date of Patent: February 4, 2014Assignee: Norfolk Southern CorporationInventors: Gibson V Barbee, Gerhard A.

Publication number: 20130239386Abstract: 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 bristle's 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.Type: ApplicationFiled: April 11, 2013Publication date: September 19, 2013Applicant: NORFOLK SOUTHERN CORPORATIONInventor: Philip D.

Patent number: 6823242Abstract: A sliding wheel detector apparatus automatically detects a sliding wheel condition of a wheel of a passing train. The apparatus includes means for parsing the cars (and trucks thereof) and segregating the same into brake valve groupings. The apparatus also includes means for determining a ratio between a wheel being evaluated and the rest of the wheels in a brake valve group. A sliding wheel will be much cooler than a properly braking wheel, and a ratio threshold is selected to detect this difference in temperature and produce an alarm.Type: GrantFiled: September 23, 2002Date of Patent: November 23, 2004Assignee: Norfolk Southern CorporationInventor: Robert Waldo Ralph

Patent number: H1961Abstract: A universal directional reference for trailing locomotives and railroad cars employs a two wire mating connector for each end of the car or locomotive, each wire having a male contact at one end and a female contact at the opposite end and in a sense opposite to the other wire. A positive polarity established on one conductor having its male contact at the leading end of the controlling locomotive causes the same polarity to appear on the female contact at the rear end of said locomotive which is connected to the male contact of the next car or locomotive thereby sustaining the pattern throughout the train. Reverse orientation of any trailing unit automatically swaps the internal polarity of its trainline wires to compensate for the otherwise reverse direction of travel.Type: GrantFiled: April 5, 1999Date of Patent: June 5, 2001Assignee: Norfolk Southern CorporationInventor: Robert S. Runyon
