The invention refers to a fish plate clamp (10) for unloading rails (1), that comprises a support element (11, 12) that comprises a first piece (11) and a second piece (12) each one located on a face of the rail (1), characterized in that: each piece of the support element (11, 12) comprises an internal mortise (13) in the area of the web (3) of the rail (1), a gripping element (14) of the rail (1) located in an internal mortise (13) of the support element (11, 12),
where the internal mortises (13) comprise an inclined surface (15) in a manner that when the gripping element (14) moves along the length of the inclined surface (15) of the internal mortise (13) in the direction of the pull of the rail (1) the gripping element (14) latches onto the web (3) of the rail (1).

A system and method for automating railroad maintenance for a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables the automating of an adaptive maintenance process for the asset that is being maintainanced. The system can identify a railroad asset scheduled for maintenance using various forms of inspection including real-time kinematic (RTK)-corrected GPS data, radar signal processing data, and real-time imaging. The system also provides for the acquisition and upload of asset pictures for verification and analysis of a railroad asset. The system can identify a next location to perform maintenance and can calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics. The system further can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset.
