摘要： A train simulator test set is disclosed that can be operably coupled to a railroad track to measure the resting impedance of that track circuit and simulate a train by varying the railroad track inductance over a set period of time. The test set can select the speed, direction, and number of trains to simulate. By applying a variable inductance on the railroad tracks, the test set can simulate a train moving at variable speeds toward and away from the island. The test set can apply inductances to the railroad tracks to simulate two or more trains moving in each direction of the tracks at the same time, along with multiple looks and routes. The train simulator test set can include simulation software to vary the parameters of the train simulation and couple a variable inductance on the railroad tracks.

摘要： An autonomous railway track assessment apparatus includes: a railway track assessment platform including a boxcar including an enclosed space formed therein; one or more power sources located on the boxcar; a controller; a first sensor assembly in electronic communication with the controller oriented to capture data from the railway track; an air handling system located on the rail car, the air handling system including an air blower and a heater/chiller; a set of air ducts in fluid communication with the air handling system and the first sensor assembly for supplying heated or cooled blown air from the air from the handling system to the first sensor assembly. Data from the railway track is autonomously collected by the first sensor assembly controlled by the controller and such data is stored on the data storage device.

摘要： The present invention provides a measuring assembly (11) for measuring a characteristic of the movement of a first rail relative to a second rail. The measuring assembly comprises a measuring gauge (15) for measuring the characteristic and a rail movement detection device (13) to which the measuring gauge is removably secured. The detection device comprises a first subassembly (19) and a second subassembly (39) wherein the first subassembly and second subassembly are slidably interconnected. The first subassembly comprises a first rail engagement portion spaced from a first end (23) of the first subassembly. The second subassembly comprises a second rail engagement portion spaced from a first end (43) of the second subassembly. The measuring gauge is secured between the first end of the first subassembly and the first end of the second subassembly. Movement of the first rail engagement portion relative to the second rail engagement portion causes the first end of the first subassembly to move away from the first end of the second subassembly, the characteristic of the movement being measured by the measuring gauge.

摘要： A method displays a course of a process of at least one railway safety unit. While using at least one device control, process data supplied by the at least one railway safety unit, are converted by dual-channel processing into first and second image data of the course of the process to be displayed. The image data are output to be displayed on a data display unit. In order to simplify the displaying of the course of the process, a pair of display spectacles having a first and a second display is used as a data display unit. The first display displays a first representation of the first image data delivered thereto that is visually detectable by the right eye, and the second display displays a second representation of the second image data delivered thereto that is visually detectable by the left eye.

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： To provide a wireless train control system that can perform a stable operation. The wireless train control system controls a wireless-control compliant train following a wireless-control noncompliant train by a ground control device. A stop limit point of the wireless-control compliant train is set by a track circuit in which a tail end position of the wireless-control noncompliant train is present. By using a track-circuit state signal indicating that the track circuit is turned on or turned off and a time-element-added track-circuit state signal indicating turn-off at a timing delayed by a set time after the track-circuit state signal has indicated turn-off, when the track-circuit state signal indicates turn-off and the time-element-added track-circuit state signal indicates turn-on, it is determined that turn-off indicated by the track-circuit state signal is caused by the wireless-control compliant train that is a train itself being present, and the stop limit point is not updated.

摘要： A modular control panel for controlling the switching operations in a miniature- or model-railway-line has grooves which reproduce the railway tracks, contacts being applied to the groove bottoms in the neighborhood of railway crossings, and is improved by the provision of a rotatable direction indicator placed at every line intersection so as to mask one or the other branch of a line bifurcation with one of its halves, the other half of said indicator defining the correct direction.
