Attachment device for fixing a tie plate and method for producing a fixing clamp
An attachment device for provisionally or temporarily connecting a tie plate to a rail includes a U-shaped fixing clamp inserted slightly into a bore of the tie plate. A force-locking connection between the tie plate and the fixing clamp is established with the aid of a clamping bolt. A stop nose automatically also effects a connection between the tie plate and the rail. A simplified tie renewal can be performed as a result of the provisional or temporary connection. A method for producing an attachment device constructed as a fixing clamp is also provided.
RAIL TIE PLATE ORIENTING AND DISTRIBUTION SYSTEM AND METHOD
A method for singulating, orientating and distributing tie plates along a section of a track of a railroad is disclosed using a vehicle adapted to travel on rails including a tie plate singulating assembly, a tie plate flipping assembly, a tie plate quarter turn assembly, and a distribution assembly. The tie plate flipping assembly flips shoulder-side down tie plates into a shoulder-side up orientation while maintaining shoulder-side up tie plates in the shoulder-side up orientation. A diverter of the tie plate quarter turn assembly advances tie plates into a rotation inducing abutment resulting in the tie plates turning toward a desired orientation. The distribution assembly distributes tie plates to accumulation slides, controlling distribution with a dealer assembly and orienting discharge assembly to distribute the tie plates in a desired spacing and orientation along the track of a railroad.

SCREWED FASTENING SYSTEM FOR RAILWAY RAILS
An improved screwed fastening system for railway rails is proposed to allow rail fastening clips to be moved onto and off the rail more easily, facilitating track installation and maintenance. One improvement comprises providing in the screwed fastening system a clip guiding device, for guiding the rail fastening clip whilst it is being driven, which has an asymmetrically-located hole for receiving the screw-threaded shank of a screwbolt. Another improvement comprises providing in the screwed fastening system a rail fastening clip and screwbolt assembly which have inter-engaging driving portions. In each case, rotation of the screwbolt in one direction brings about translational movement of the rail bearing portion of the clip away from the screwbolt, and rotation of the screwbolt in the opposite direction brings about translational movement of the rail bearing portion of the clip towards the screwbolt.
Hot Forged Tie Plate for Railroad
A railroad tie plate has a generally prismatic body including a field side flange and a gauge side flange connected by an intermediate portion. The intermediate portion includes a rail seat for positioning a railroad rail. At least one of the flanges includes a protrusion extending in a thickness dimension of the tie plate. A hole extends into the at least one protrusion so as to receive a retaining device, such as an e-clip. The tie plate is made by hot forging, having a microstructure comprising pearlite and alpha-ferrite. The net shape of the tie plate may be achieved by forging without subsequent material addition and without subsequent material removal.

KEYWAY TIE
A tie having a non-linear keyway under the overlying rail to provide support to restrain lateral and longitudinal movement of the rail. A fastening system to hold rails down on a tie comprises a rail plate that may be fastened to the tie within the keyway. The fasteners are protected to avoid damage in case of a derailment or other adverse conditions. Also disclosed are visual inspection mechanisms to assist with determining whether a fastening system is securely attached to the tie.

RAILWAY ANCHOR APPLICATOR MACHINE
Provided herein is a workhead assembly for a railway anchor applicator that can have an anchor clipping mechanism can be configured to operably couple to an anchor receiving mechanism. The anchor clipping mechanism can have an apply lever configured to be coupled to an actuator. The apply lever may include a fulcrum configured couple to a moveable frame of the workhead. The anchor clipping mechanism may include an applicator arm having an elongated body with a first end, a second end at a distal location, and a middle portion between the first end and the second end. The middle portion may be configured to pivotably couple to the apply lever and a guide pin is located on the second end. An apply cam can be configured to couple to the moveable frame. The apply cam can have a slot configured to receive the guide pin.
