One embodiment of the invention comprises a system for operating a railway vehicle (8) comprising a lead powered unit (14 / 15) and a non-lead powered unit (16 / 17 / 18) during a trip along a track The system comprises a first element (65) for determining a location of the vehicle or a time from the beginning of a current trip, aa processor (62) operable to receive information from the first element (65) and an algorithm embodied within the processor (62) having access to the information to create a trip plan that optimizes performance of one or both of the lead unit (14 / 15) and the non-lead unit (16 / 17 / 18) in accordance with one or more operational criteria for one or more of the vehicle (8), the lead unit (14 / 15) and the non-lead unit (16 / 17 / 18).

This management system for managing the route of a rail vehicle travelling on a rail network between a departure point and an arrival point includes a central processor unit configured to cause a change in the route of the rail vehicle between a route-change node and a convergence node at which the changed route converges back on the initial route. The central processor unit is further configured to determine a set of routes comprising all of the possible routes between the route-change node and the convergence node, and compare the set of routes with the initial route so as to cause the route change to be made along the route that is closest to the initially-planned route.

A geographic information system (GIS) displays geographic roadway data, geographic track data and geographic train position data. The GIS includes a GIS database having static roadway and track data. A computer aided dispatching (CAD) system includes a task to determine an occupied track section. A web server includes a first routine determining geographic starting and ending positions of the track section, a second routine displaying geographic information regarding the static roadway and track data, and a third routine determining geographic information regarding the occupied track section from the geographic starting and ending positions of the track section and from the GIS database. A client system communicates with the web server to receive and display the geographic information regarding the static roadway and track data, and to receive and display the geographic information regarding the occupied track section with the geographic information regarding the static roadway and track data.

A method for managing railcar movement in a railyard based on the flow of railyard tasks, using a system that includes a computer including a processor, a memory device, and a database. The railyard includes six subyards including a surge yard, a receiving yard, a receiving inspected (RI) yard, a classification yard, a departure yard and a departure inspected (DI) yard. The method uses initial parameters, input to the computer, to simulate railyard task flow utilizing a yard performance model. Based on the simulation, the method determines if a train schedule can be met.

One embodiment of the invention includes a system for operating a railway network comprising a first railway vehicle (400) during a trip along track segments (401 / 412 / 420). The system comprises a first element (65) for determining travel parameters of the first railway vehicle (400), a second element (65) for determining travel parameters of a second railway vehicle (418) relative to the track segments to be traversed by the first vehicle during the trip, a processor (62) for receiving information from the first (65) and the second (65) elements and for determining a relationship between occupation of a track segment (401 / 412 / 420) by the second vehicle (418) and later occupation of the same track segment by the first vehicle (400) and an algorithm embodied within the processor (62) having access to the information to create a trip plan that determines a speed trajectory for the first vehicle (400), wherein the speed trajectory is responsive to the relationship and further in accordance with one or more operational criteria for the first vehicle (400).

An embodiment of the invention provides a method for controlling access to content in a social networking website, wherein a connection is established between a first user and a second user on the social networking website. Content on the profile pages of the first user is categorized into a first content category and a second content category. The first content category includes content created before the connection between the first user and the second user was established. The second content category includes content created after the connection between the first user and the second user was established. Content in the first content category is also categorized into a first subcategory and at least one second subcategory. Access by the second user is restricted to the first content category. Specifically, the second user is prevented from viewing content in the first subcategory and permitted to view content in the second subcategory.
