Abstract: A rail for a rail vehicle track that has a longitudinal extension (L), an apparatus for identifying the rail, and a method for identifying the rail. An identification marker is attached along the longitudinal extension (L) of the rail on an inner side and/or an outer side of the rail. The identification marker is composed of a plurality of symbols, each symbol having at least one partial length (TL) of 0.15 meters, and one identification marker having at least eight symbols. The rail makes it possible for the rail vehicle to identify the rail laid as track during travel in normal operation.

Abstract: An assembly monitors exterior regions of a rail vehicle. In the region of the front side of the rail vehicle, a driver's cab is arranged, which driver's cab has a driver's cab field of view in a first direction of travel. A first lateral region has a first camera system oriented in the direction of travel, which optically captures an angular range along the first lateral region as a first lateral field of view. A second lateral region has a second camera system oriented in the direction of travel, which captures an angular range along the second lateral region as a second lateral field of view. The first and second camera systems are connected to a display device so that image series of the lateral fields of view in the first direction of travel are displayed to the traction vehicle driver in addition to the drivers cab field of view.

Abstract: A system includes at least one train having one or more sensors and a device remote from the at least one train. The device is configured to communicate with the at least one train via one or more networks, collect data from the one or more sensors of the at least one train at a plurality of different locations in a defined area, and generate a map of the one or more tracks based on the data collected from the one or more sensors of the at least one train at the plurality of different locations in the defined area. Other example systems and computer-implemented methods of mapping one or more railroad tracks in a defined area are also disclosed.

Abstract: Provided are methods for measuring forces exerted on rails or such like as a cause of the transit of vehicles on said rails, for determining the values of different parameters, and for calculating coefficients or other variables. Also provided are systems of devices that allow for the taking of values and for the recording, processing, and sampling of the resulting information based on measurement methods that allow directly measuring the lateral force, in a more simplified manner of installation resulting in lower cost in sensors and with greater precision based on the configuration of said sensors and their individual valuation.

Abstract: A system and method for adjusting light emitter output for a railway track inspection system based on data feedback from one or more sensors. The system includes: a power source; a light emitting apparatus emitting light energy toward a railway track; a 3D sensor acquiring three-dimensional data of the railway track; a shaft encoder emitting pulses at a rate that corresponds to a speed of the railway track vehicle; and an algorithm operable on processor to: analyze the three-dimensional data from the 3D sensor; receive pulses from the shaft encoder; and adjust a light emitter control output value based on the analyzed three-dimensional data and the received pulses. A controller in communication with the processor is configured to control the light intensity of the light emitting apparatus in response to the light emitter control output value.

Abstract: A route examination system includes a thermographic camera configured to be logically or mechanically coupled with a vehicle that travels along a route. The thermographic camera is also configured to sense infrared radiation emitted or reflected from the route and to generate a sensed thermal signature representative of the infrared radiation that is sensed. The system also includes a computer readable memory device configured to store a designated thermal signature representative of infrared radiation emitted from a segment of the route that is not damaged. The system also includes an analysis processor configured to determine a condition of a first portion of the route relative to other portions of the route at least in part by comparing the sensed thermal signature and the designated thermal signature.

Abstract: A derail alarm system for notifying a tamping machine operator that a tamping projector buggy is in a derailed condition. A rail sensor with an ultrasonic beam attaches to a tamping projector buggy to sense alignment with a metal rail. When the ultrasonic sensor detects an out-of-tolerance condition, aural and red-LED light visual indications are electronically provided to the tamping machine operator. The tamping machine operator may disable the aural indication and change the red-LED indication to an amber-LED indication until the ultrasonic sensor detects an in-tolerance condition. A limit switch deactivates the cradle sensor when the tamping projector buggy is raised and stored in the travel position for a higher speed transport condition.

Abstract: A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.
