摘要： A system is disclosed to selectively initiate braking at a rear section of a railway train upon initiation of a selected front braking condition at the front section of the railway vehicle. The system utilizes an air sensor preferably constructed in the form of an insect excluder device to detect release of brake pipe air from an exhaust port upon initiation of braking at the front section of the vehicle. An appropriate signal is produced by the air sensor, thus permitting detector circuitry to detect that front braking has been initiated. A transmitter, typically located in the cab of the locomotive, is electrically connected to the detector circuitry. When the detector circuitry indicates that the selected front braking condition has been initiated, the transmitter transmits a brake initiation signal to a receiver located at the rear of the vehicle. The receiver then actuates pneumatic braking equipment at the rear to initiate rear braking. The air sensor may include a generally rigid insect shield connected to actuate the armature of an electrical switch upon passage of air. Such an air sensor may also be constructed utilizing a deformable insect shield configured to operate as a variable capacitor when air passes through the exhaust port. If connected in a resonant circuit, this variable capacitor may provide a detectable voltage variation which can be used to indicate initiation of front braking.

摘要： A railroad searchlight signal for producing light signals of selected colors. The searchlight uses a reflector that has an inner surface of reflective material and a focal point. One or more light emitting diodes are provided at the reflector focal point. When a current is supplied to the light emitting diode from a variable current power source, a light having a color that varies dependent upon the current is produced. The colored light produced at the light emitting diode is then directed outward of the reflector as a beam. At least one color filter that allows light of a respective color to pass therethrough is preferably provided proximate the reflector. Light that passes through the color filter is detected by a light detector such as a photovoltaic cell, a phototransistor or a photodiode.

摘要： A brake hose coupling having a locking mechanism and a pressure relief valve for connecting a telemetry unit to the air brake pipe line of a railway train. The locking mechanism positively latches the brake hose coupling to the "glad hand" brake pipe hose coupling and causes the venting of the entrapped pneumatic pressure by the relief valve when the locking mechanism is unlatched.

摘要： An apparatus for providing a light signal to a signal unit at an overhead location along a railway signal structure, particularly a cantilever signal structure having a vertical mast and an arm assembly extending therefrom. Signal units may be located along the mast and/or the arm assembly. A light source is provided at or near ground level so as to be readily accessible by a maintainer and is connected by fiber optic cable to the signal units. Thus, light produced by the light source travels through the optical fiber to the signal units.

摘要： A railway switch circuit controller having a housing with a bottom surface and opposed side surfaces. The bottom surface has a raised planar boss provided thereon, in which the raised boss is cast upon the bottom surface and is then machined so as to have a flat surface and a selected height. The side surfaces have respective openings provided therethrough for receiving a shaft. The shaft is rotatably disposed through the side surface openings and has one or more cam segments disposed thereupon. Each cam is engageable with a follower in which the follower is biased to a first position but rotation of the shaft causes the cam to move the follower to a second position. The follower is connected to a movable contact of a contact spring assembly. The contact spring assembly also has one or more sets of first and second generally nonmovable contacts in which the movable contact is disposed between the two nonmovable contacts. The contact spring assembly is secured to a terminal board. The terminal board has a planar portion that is matable and is secured to the raised boss of the controller housing bottom surface.
