The present invention relates to a method for remotely controlling the status of graphic user interfaces such as monitors, panels, displays, screens and others, used in railway or transportation systems. For achieving a reliable safety level, so that a person can be sure that the information displayed by the graphic interface in real time correspond to the effective situation of the transportation network, there is provided a feedback control loop between an image elaboration-generation block, and a safety block. According to a preferred solution, the communications between the blocks of the control loop are encrypted. With the control method of the present invention, it is possible to achieve a top safety level in the railway networks, even when using commercially available graphic user interfaces, such as COTS terminal.

Tools .[.(such as system, apparatus, methodology, etc.).]. may be provided to control traffic over a railway track section, .Iadd.and more particularly, .Iaddend.when a railway worker is working on or near the track section.[.. Move particularly, when traffic over the track section is to be blocked.]., .Iadd.a block is placed to prevent trains from traversing the track section. Further, .Iaddend.a release code is generated and sent to .[.an electronic contact address of the railway worker. Traffic through the track section is blocked until the release code is entered in.]. .Iadd.a user terminal. The block is removed from the track section when the release code is received by .Iaddend.the system.

A system for modeling risk of rail buckling in railroad infrastructure is presented. The system can receive a myriad of data related to railroad tracks and/or railroad operations, and weight the data using specially-designed weighting factors that can be unique to each data type. The weighted data can be transformed via specialized algorithms to generate location scores reflective of a risk isolated to a particular area. The system can further utilize additional specialized algorithms to elucidate how such isolated risk can be extrapolated from one location to another. The system can implement a multilayer approach, formulating one or more layers of risk models and aggregating such models into an overarching risk model that can more-accurately forecast risk of rail buckling in a railroad track.

The invention relates to a CTC3.0-based locomotive decoupling and coupling plan automatic generation and execution method. According to the method, by upgrading a track occupancy display terminal and a data platform in a CTC3.0 system, automatic generation of a locomotive decoupling or coupling plan is triggered when the route display terminal receives a train plan, so as to complete a locomotive decoupling or coupling task. The method has the advantages of high automation degree and high transportation efficiency.

The present aspects refer to a method for prioritizing railway crossing flows comprising: defining residence location nodes, daily-activity location nodes and level crossing nodes within a zone of influence; generating a graph comprising the residence location nodes, daily-activity location nodes and level crossing nodes and a set of edges, wherein said edges connect the residence location nodes, daily-activity location nodes and level crossing nodes, generating a connected component containing residence location nodes, daily-activity location nodes and level crossing nodes; and obtaining a vector comprising the level crossing nodes in descending order of the value assigned to each level crossing node. The present aspects also refer to a memory storage medium comprising computer-executable instructions for implementing a method for prioritizing railway crossing flows.

A method and system for determining a separation distance between a first object and a second object comprises using a search module associated with a first object comprising a first transponder having a unique address. The method includes using a reply module associated with a second object comprising a second transponder having a different, unique address. The method includes the search module transmitting a search signal on a first frequency, said search signal including the address of the first transponder and the address of the second transponder. The reply module receives the search signal and locally validates the address included in said received search signal for the second transponder, whereby, if the validation is positive; the reply module transmits a reply signal on a second, different frequency.

A system for visually assisting an operator of a railcar mover that provides a visual display and a pair of alignment lines superimposed on the image of the display to assist the operator to properly align a railcar mover to the railroad rails when transitioning from driving on the road to driving on the railroad rails. The system further includes a set of cameras positioned around the railcar mover and a processor, which can create a composite image of a top view of the railcar mover to further assist the operator position the railcar mover properly.
