Universal slide-plate
A universal slide-plate includes a body and a drop-in shoulder member with a plurality of retaining members that cooperate to selectively connect the universal slide-plate and a stock rail to a rail platform and/or tie. The universal slide-plate has a slide surface configured to support a moveable point rail thereon. The universal slide-plate may be selectively removed and repositioned relative to a rail platform and/or tie.
Apparatus and Method for Correcting Damage to Rails and Railway Crossovers
A method of repairing a defect in a damaged rail of a railroad track comprises positioning a rail profiling device on the rails of the railroad track proximate a defect; securing the rail profiling device to the railroad; adjusting its grinder according to a selected value of wheel cone angle to create a profiled running surface over a portion of the damaged rail; creating a median zone using the grinder to remove material from the damaged rail adjacent the defect at a depth corresponding to at least a maximum depth of the defect; creating an incline from the top of the rail and leading to the median zone and one incline leaving the median zone to the top of the rail by using the grinder to grinding material off the damaged rail.
Saborage-resistant switch device for moving railroad switch points
The switch machine disclosed uses electro-hydraulic power to move the throw rod against the resistance of redundant mechanical springs and the switch point, for half of its stroke. Once the switch points have moved past mid-stroke the spring force in the machine is released and assists in the closure of the switch points against the stock rail. All hydraulic force is removed when the power unit is turned off. The redundant spring assembly holds the switch points firmly against the stock rail with 2000 lbs of holding force. This machine can be described as a power operated spring switch.

Arrangement, test rig and method for testing a switch mechanism for changing over the path traveled by a rail vehicle on a track
A switch mechanism serves for changing over the path traveled by a rail vehicle on a track. The switch mechanism has an electric motor, the rotational movement of which is converted into a linear movement by way of a spindle rod or toothed rack. Part of the mechanical system is usually also a coupling, which prevents excessive force from being exerted on the track. A flexible adaptation for the test slider of a switch drive enables complete testing of the switch drive on a test bench. The switch drive can be tested in the final state because the test slider does not need to first be removed and then reinstalled only after testing. Separate testing of the test slider in terms of its function and its high voltage strength is therefore no longer necessary. After the testing, no additional steps need to be carried out on the switch drive.

Conveyor system for transporting articles
A conveyor system for transporting articles, comprising a rail system that comprises a plurality of track sections and at least one switch point, by which, via a switch point drive, a first track section can be connected to a second track section or to a third track section of the rail system. At least one drivable transport trolley can be driven along a path of movement on the rail system. A communications system with comprises at least one communications line that extends along the path of movement of the at least one transport trolley. A trolley communications unit disposed on the at least one transport trolley interacts with the communications line. The switch point drive can be controlled by means of a switch point control system, which is connected to the at least one communications line.
