摘要： In one embodiment, a method includes receiving first Light Detection and Ranging (LiDAR) data associated with a railroad environment, extracting an asset from the first LiDAR data associated with the railroad environment, and superimposing the asset into a spatial model. The method also includes receiving a field indication associated with a modification to the railroad environment and modifying the spatial model in response to receiving the field indication associated with the modification to the railroad environment. The method further includes receiving second LiDAR data associated with the railroad environment and comparing the second LiDAR data to the modified spatial model.

摘要： An automated speed control system for a locomotive having a tractive effort mechanism for moving the locomotive along a track and a braking mechanism for reducing the locomotive's speed along the track. The system including a locomotive controller that includes a memory to store computer-executable instructions, and a processor in communication with the memory to execute the instructions to retrieve one or more track grade maps each indicative of a grade of at least a portion of the track along which the locomotive is travelling, retrieve train makeup, obtain a maximum distance to a specified stopping point of the locomotive along the track, and dynamically calculate a speed limit for movement of the locomotive along the track, according to the retrieved track grade map, retrieved train makeup data, and obtained maximum distance to the specified stopping point.

摘要： Tools (such as system, apparatus, methodology, etc.) may be provided to control traffic over a railway track section, and more particularly, when a railway worker is working on or near the track section, a block is placed to prevent trains from traversing the track section. Move particularly, when traffic over the track section is to be blocked Further, 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 the system a user terminal. The block is removed from the track section when the release code is received by the system.

摘要： A system and method obtain first image data of a route at a location of interest from a first optical sensor disposed onboard a vehicle system moving along the route. The first image data depicts the route at the location of interest prior to passage of the vehicle system over the route at the location of interest. Second image data of the route at the location of interest is obtained from a second optical sensor disposed onboard the vehicle system. The second image data depicts the route at the location of interest after passage of the vehicle system over the route at the location of interest. A determination is made as to whether a change in the route has occurred at the location of interest by comparing the first image data with the second image data.

摘要： An object is to improve the accuracy of prediction of deterioration of railroad ground equipment. Provided is a maintenance assistance system for railroad ground equipment, comprising: an environmental-information storage part storing environmental information containing information on weather observed at a plurality of geographical points and on geographical conditions at the geographical points; and an environmental-load estimation part holding a relational formula indicating the relationship between aged deterioration of railroad ground equipment and the environmental information, and configured to, upon specification of railroad ground equipment for which to execute deterioration prediction, acquire the environmental information which is recorded at a point near the installed position of the railroad ground equipment, during the target period of the deterioration prediction, and predict the degree of aged deterioration of the railroad ground equipment by using the acquired environmental information and the relational formula.

摘要： A method of determining the geographical position of a rail vehicle travelling on a defined route that has a number of known stopping locations separated by known distances. The method comprises steps of: recording a linear speed signal of the vehicle; processing the linear speed signal to identify a plurality of preceding stationary periods when linear speed equals zero, including a last stationary period, and to calculate the distance traveled between the plurality of preceding stationary periods; comparing the calculated distances with the known distances between stopping locations, to match the last identified stationary period to a corresponding one of the known stopping locations and identify the direction of travel of the rail vehicle; and determining the geographical position of the rail vehicle by processing a portion of the speed signal obtained since the last identified stationary period, to calculate the distance traveled from the corresponding stopping location.

摘要： An electronic tag (Radio-frequency identification) device for a rail traffic concrete prefabricated parts is disclosed, which comprises a bracket. A column is on a top of the bracket. There is a groove on a top end of the column. The electronic tag is inside groove. The electronic tag device further comprises a waterproof end cap which is put on the top of the column. The pressure relief holes, the release-proof clasps, the rebar clamps, the groove on the column, etc. ensure a stable fixation of the electronic tag inside the concrete railroad sleeper. The waterproof end cap is able to protect and fix the electronic tag.

摘要： A train control system configured to automatically execute and ensure compliance with all requirements for radio blocking. A radio blocking module of the physical train control system of a lead train retrieves and displays the appropriate clearance points for acceptance by the train driver of the lead train. Once accepted, the clearance points are transmitted to a trailing train for display and acceptance by the train driver of the trailing train. An accepted clearance point is passed to the train control system for use as the next destination point for navigation purposes. The train control system can also electronically log all acts to comply with applicable radio blocking requirements.

摘要： A method and an apparatus for a train control installation are disclosed, and are based on the absolute permissive block concept. The train control installation employs a plurality of generic absolute block signal units (ABSU), wherein each signal unit includes means for detecting the crossing of a train passed a discrete point, means for exchanging data with adjacent ABSUs, means for generating and communicating a movement authority limit to a train, means for generating and displaying a signal indication, and means for enforcing a stop aspect. The train control installation can be used in conjunction with a communication based train control (CBTC) system to provide a degraded mode of operation without impacting the availability and the reliability of the CBTC system. Further, the train control installation has a self-healing feature to maintain train service during an ABSU failure.
