摘要： A railroad turnout including a switch having runoff plates with stop lugs spaced farther apart than the width of the switch point base so that flexure of the switch points downstream of the heel spread is permitted. Floating heel blocks are affixed to the stock rails at the heel point to maintain the conventional heel spread. A smooth ride through the turnout is further assured by additional switch rods, uniform risers in the switch and guard rails associated with the frog of the turnout.

摘要： A railroad spring frog assembly for trackwork installations includes a rigid rail and a flexible spring wing rail. The flexible spring wing rail is rigidly affixed between one end which engages a wing point rail and the other end which connects to a closure rail at the toe end of the frog support means. When a rail car enters the frog and a wheel flange engages the spring wing rail to pass between it and the long point rail the spring wing rail bends away from the long point rail to define a flangeway therebetweeen.

摘要： A hydraulic system having a plurality of motor driven pumps in parallel legs, at least one being active and one in reserve, so combined with sensors to sense pump efficiency and filter efficiency that a condition deemed pump failure or filter failure results in activating the reserve leg and deactivating the inefficient leg. Other sensors detect flow meter failure and establish warnings of conditions deemed near-failure. The system may be duplicated both on the pressure side and return side of the pumps.The system reservoir is characterized by a tank for return fluid to be cleaned and a separate tank for the fluid to be delivered under pressure; so constructed as to (a) remove turbulence, (b) prevent vortex overlap, (c) remove silt fines and (d) maintain a proper pumping level.

摘要： A guard rail assembly for supporting a guard rail adjacent to and higher than a traffic rail. Brace means are provided on the outer side of the guard rail away from the traffic rail. An upper portion of the brace means engages the outer face of the guard rail head, and a lower portion engages the web of the guard rail. A shim plate supports the base of the guard and has an inner upwardly extending lip in engagement with an inner face of the guard rail base. A tie plate underlies and supports the rails, brace means and shim plate.

摘要： A railroad frog has either a cast or rail-built point, resting on a baseplate which is fastened to ties. A pair of heel rails are attached to the point, to the ties and to traffic rails. A pair of movable wing rails extend from the toe of the frog to a location adjacent the point of the frog. At the frog point an open wing rail forms a flangeway with the point, while the other, closed wing rail cooperates with the point to form a continuous tread surface through the frog. The wing rails are alternately thrown between the open and closed positions by an actuator. A series of stops define the open wing rail position and act to hold down the open wing rail. The wing rails have hinges which allow them to move. The wing rails have a full rail base at the hinges. Adaptor plates allow use of the frog on concrete ties.

摘要： A high-speed switch machine for actuating railroad switch points. The machine has an electric motor which drives a hydraulic pump. The pump supplies pressure fluid to a hydraulic cylinder adapted to move the switch points from an initial to a second limit position. A four-way, two-position hydraulic control valve directs fluid to the cylinder such that the cylinder automatically operates in an extension and retraction cycle. The uni-directional motor and two-position control valve minimize response times of the actuating components so that the switch points are thrown in a short time period.
