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.

A system for working on a track with a track maintenance machine has a machine controller and a work unit controlled thereby, with sensors being arranged to monitor the work unit. In this context, the sensors are coupled to a data acquisition module for the separate recording of sensor data, with the data acquisition module being connected to a computing unit in which a first algorithm for calculating result data from the sensor data is set up. In this way, the system contains additional structural components for processing sensor signals. With the data acquisition module and the computing unit, different evaluations of the working mode can be performed independently of an existing monitoring function.

Provided is a rail head abrader including a base, a blade, a vertical measurement section and a horizontal measurement section; an upper end surface of the base is arranged horizontally and a base bevel edge intersects a base vertical edge; the blade is disposed on the base and perpendicular to the upper end surface of the base, an upper portion of the blade is provided with vertical wear rail type selection lines; the vertical measurement section includes a vertical scale frame, a vertical digital display device, and a vertical scale cursor; the horizontal measurement section includes a horizontal scale frame, a horizontal measuring rod, measuring rod rail type selection lines, a horizontal digital display device, and a horizontal scale frame cursor, and a horizontal scale frame cursor locating line corresponding to the side wear rail type selection lines; the horizontal measuring rod is slidably mounted on the horizontal scale frame.

A track maintenance machine for carrying out track position corrections includes a machine frame movable by on-track undercarriages on rails of a track and a track position measuring system having two outer measuring devices and a central measuring device with a common reference base, relative to a longitudinal direction of the machine. The measuring devices are defined in their position relative to the rails. Two mutually aligned measuring chords are tensioned or stretched as a reference base between the outer measuring devices. The central measuring device includes a measuring transducer for detecting position data of the two measuring chords. The position data are fed to an evaluation device in order to determine a longitudinal level for each rail and a versine. Thus, two measuring chords are sufficient to detect all of the track parameters. A method for operation of a track maintenance machine is also provided.

A method for compaction of a track ballast bed uses a tamping unit including two oppositely positioned tamping tools which are actuated with vibrations and are lowered into the track ballast bed during a tamping operation and moved towards one another with a squeezing motion. A progression of a force acting upon the tamping tool over a path covered by the tamping tool is recorded during a vibration cycle by sensors disposed at the tamping unit for at least one tamping tool. At least one characteristic value is derived therefrom and used to carry out an evaluation of the tamping operation and/or of a quality of the track ballast bed. The tamping unit is thus used as a measuring apparatus during operative use. A device for performing the method is also provided.
