Abstract:
A method for inspecting a rail vehicle includes receiving signals representative of temperatures of a wheel of the rail vehicle and generating a sensed wheel temperature profile of the wheel based on the signals. At least a portion of the sensed wheel temperature profile is representative of the temperatures of the wheel. The method also includes identifying waveform attributes in the sensed wheel temperature profile and designating the sensed wheel temperature profile as at least one of a typical wheel profile and an atypical wheel profile based on the waveform attributes in the sensed wheel temperature profile.

Abstract:
A rail applicator assembly includes a rail having a head portion, a base portion, and a web portion extending between the head portion and the base portion. The head portion defines an outer surface. An applicator for applying a friction modifying material to the surface of the rail includes a foam body and an applicator support. The foam body is secured to the applicator support and defines a flow passageway that extends through the foam body for friction modifying material to flow through.
Abstract:
La présente invention décrit une méthode et dispositif de contrôle de présence d'au moins un rail (1) de guidage d'un véhicule guidé, ledit dispositif comprenant: - un premier détecteur (41) situé en aval d'une roue (3), ledit détecteur (41) étant apte à détecter la présence dudit rail (1) et à transmettre un premier signal (S A ) relatif à ladite présence dudit rail à un organe de contrôle (5), caractérisé en ce que - un second détecteur (42) situé en amont de ladite roue est apte à être connecté en parallèle avec ledit premier détecteur (41), et à détecter ladite présence dudit rail (1), - ledit second détecteur (42) est apte à communiquer audit organe de contrôle (5) un second signal (S B ) relatif à ladite présence dudit rail.
Abstract:
El invento consiste en un transporte urbano continuo, que se desplaza en forma aérea por avenidas anchas. Consta de dos niveles, un para usuarios (7) y el otro para mercancías (8) cuyos extremos son dos guías de acero (3 a y 3b) por las que se desplazan trenes (4) en distintos sentidos. Junto a los mismos hay dos pasillos auxiliares (7), uno para cada sentido, cuyo suelo es una cinta transportadora (2) que va de estación a estación. Cincuenta metros para subir y acelerar hasta igualarse en velocidad y nivel con los trenes, cuatrocientos metros de paso de usuarios y cincuenta metros finales para desacelerar y bajar a la siguiente estación. El tren no necesita detenerse para que los usuarios suban o bajen, reduciendo cinco veces los tiempos de viaje y transportando cien veces más usuarios.
Abstract:
An ultrasonic railroad rail inspection system, apparatus and method for in situ rail inspection including a wheel assembly containing a fluid-filled tire and an ultrasonic transducer mounted within the wheel assembly. The transducer is supported in the tire such that the ultrasonic beam generated by the transducer has a beam axis that intersects a head of a railroad rail at a position offset from the longitudinal median plane of the rail to the side of the head penetrated by the ultrasonic beam. The ultrasonic beam is reflected by flaws in the rail in the form of echoes. The echoes return to the transducer identifying the location of flaws.
Abstract:
A clamp device for mounting a rail device onto a railroad rail includes a clamp body having an upper section and a lower section. The clamp body defines a recess portion between the upper and lower sections and a bore extending through the lower section of the clamp body. A bolt having a first end and a second end extends through the bore of the clamp body. The clamp device also includes a quick release mechanism having a lever arm and a cam member pivotally connected to the second end of the bolt. The lever arm is connected to the cam member and has a clamped position and a released position whereby pivoting the lever arm from the released position to the clamped position draws the first end of the bolt and the clamp body together.
Abstract:
The present invention relates to a device (1) for lifting a rail-based vehicle (3) while the vehicle is standing on a rail (5). The device comprises a supporting frame (7) adapted to at least in part rest on the rail, and a lifting member (9) adapted to apply a lifting force on the rail-based vehicle in order to lift at least one wheel (11) of the rail-based vehicle from the rail.
Abstract:
A method for signaling, guiding and alerting passengers in the platform area of a traffic station, in which method passengers are signaled, guided or alerted by means of sequentially arranged light sources, such as LED lights, fastened or embedded on a surface, particularly the surface of a passenger platform. In the method, passengers are alerted of the passage route of a traffic vehicle and/or of an arriving traffic vehicle by a first light source string (4) arranged in the border area of the platform (1 ), including sequentially arranged light sources (40) that are spaced apart, by means of a first mode, for instance a first color, of the light source, and that passengers are guided into the transport vehicle (3) and/or out of the transport vehicle to the platform area (1 ) by switching the mode of at least part of the light sources in the first light source string (4) from the first mode to a second mode, such as a second color. The invention also relates to an arrangement.
Abstract:
A temperature warning system for a vehicle includes a thermal plug (46) disposed on the wheel end assembly (16) of the vehicle. The thermal plug is in fluid communication with an air supply (30) and with a flow sensor (31). The flow sensor is operatively connected to a warning light or indicator (41). Excessive heat in the axle spindle end (14) and/or the wheel end assembly causes a fusible material in the thermal plug to melt allowing air to flow from the air supply through the thermal plug thus activating the flow sensor. The flow sensor in turn activates the warning light or indicator alerting the driver of the vehicle of a problem condition at the wheel end assembly and/or axle spindle.
