| 121 | Device and method for error monitoring for undercarriage components of rail vehicles | US12598796 | 2008-05-16 | US08234917B2 | 2012-08-07 | Thomas Burkhart; Ulf Friesen |
| The invention relates to a device for monitoring errors in undercarriage components of rail vehicles, having at least one acceleration sensor which works with an evaluation unit. At least one acceleration sensor is arranged on the undercarriage of the rail vehicle in such a manner that its direction of detection has at least one component parallel to the vertical axis (z-direction) of the rail vehicle. The invention proposes that the acceleration sensor is constructed in such a manner that it delivers a measuring signal which contains the signal portion corresponding to a ground acceleration, or represents a signal corresponding to a ground acceleration, and that the evaluation unit has a routine for testing functions of the acceleration sensor, the routine controlling an error signal if the measuring signal delivered by the acceleration sensor contains no signal portion corresponding to a ground acceleration. The routine also suppresses the error signal if this is not the case. | ||||||

| 125 | Sideframe wheelbase gauge | US09289879 | 1999-04-12 | US06272759B1 | 2001-08-14 | Terry L. Reichenbach, Sr.; Les L. Unger; Terry L. Tilley; Leonard D. Thomason |
| A gauge is provided that is useful in measuring the horizontal wheelbase of a railway freight car truck sideframe. The gauge itself is comprised of a main horizontal body section usually of a single piece of aluminum bar stock. A stationary depending leg extends downwardly and is affixed to near one end of the main horizontal body section. A bearing slide assembly is affixed to the main horizontal body section near its other end. A measuring leg depends from the bearing slide assembly and is movable along the bearing slide assembly. An indicator scale is associated with the measuring leg so that its relative position with regard to the main horizontal body can be readily measured from a scale affixed thereon. The stationary depending leg is brought into contact with one edge of a pedestal jaw of the railway freight car sideframe, and the measuring leg is moved into contact along the bearing slide assembly with an opposite edge of the opposite pedestal jaw. A measurement reading of the wheelbase of a sideframe is then made. | ||||||

| The position of an event, such as emergency braking, of a railroad vehicle enroute on a track mapped on a chart is accurately recorded by continually sensing the degree and direction of track curvature, and recording the track curvature and event data for later display. Speed is also recorded as a function of time to provide a scale as an aid to interpolation of a recorded event position between recorded curves. The event position thus recorded and identified by nearby curves in the track is accurate to within a small fraction of a mile. | ||||||

| 134 | Derail alarm systems | US14996223 | 2016-01-15 | US09981676B2 | 2018-05-29 | Edward Stanton Sandstrom |
| 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. | ||||||
| 135 | Automated in motion railway seismic wheel failure detection system | US14685283 | 2015-04-13 | US09969409B2 | 2018-05-15 | Frank Carl Van Der Merwe |
| Systems and methods for detecting in motion railcar seismic data generated by defective railcar axles of a train traveling on a track. The method uses two or more seismic sensors on the side of the track to capture seismic noise generated by railcar wheels. A wheel that exceeds a preset seismic noise threshold in amplitude, will trigger a wheel tracking algorithm that calculates seismic phase shift data related to the actively tracked wheel noise level, to determine the precise location, in real time, of the faulty wheel carriage while moving. Knowing the precise location of the tracked wheel allows the system to isolate the railcar and capture the railcar and wheel carriage identification information.Subsequently, a railcar log is made on a computer database with the railcar identification information and made available to control centers via ground or satellite links. | ||||||
