Positive friction control composition for railways

A friction control composition having high and positive factional properties for sliding steel surfaces includes a water insoluble hydrocarbon that enables a reduced water content, a rheological additive, a freezing point depressant, a friction modifier, and a lubricant.

METHOD AND APPARATUS FOR GAUGE-FACE LUBRICATION
20170057524 · 2017-03-02 ·

A gauge-face lubrication assembly and related methods of use in which a removable and replacable applicator member is positioned proximate a gauge-face for lubrication of a rail member. Generally, the replaceable applicator member can be molded of a resilient polymeric material having shaped-memory properties. The replaceable applicator member includes one or more molded lubricant channels for delivering lubricant supplied by a lubrication system to the gauge-face. Each molded lubricant channel can include a molded seal for sealably engaging a lubrication bracket that retains the applicator member in position against the gauge-face. The removable applicator member can further include a liner for physically engaging the gauge-face and protecting removable applicator member. The applicator member can include a coupling portion that insertably interfaces with a bracket channel defined in the lubrication bracket, whereby the applicator member can be removed and replaced in the event of damage or wear.

Rail road track lubrication apparatus and method
09561809 · 2017-02-07 · ·

An apparatus and method for applying lubricant to a rail road track. The apparatus comprising a control module; a housing; a lubricant distribution block; and a plurality of tubes for connecting the control module to the housing wherein the housing houses the lubricant distribution block. The control module is positionable in close proximity to the rail road track and the housing is positionable adjacent to and along a section of rail road track to be lubricated. The lubricant is stored in a vessel in the control module and pumped from the control module to a lubricant distribution nozzle connected to the housing and wherein sliding the lubricant distribution nozzle along the section of rail road track in a first or second direction distributes lubricant along the section of rail road track.

Drone with railway driving capabilities
12296993 · 2025-05-13 · ·

A drone with railway driving capabilities has a drone body and at propeller arms. Each propeller arm has a propeller assembly having a propeller driven by a motor assembly. The propeller assembly of at least one propeller arm has a rotatably mounted propeller guard placed coaxially with the propeller. The propeller guard is shaped as a train wheel and is driven by the motor assembly. The propeller arm has an actuated joint for providing the propeller assembly with at least one rotation degree of freedom so that the propeller can be rotated between a flight mode and a driving mode and back. The flight mode involves a more horizontal orientation of the propeller assembly for providing an upwardly directed thrust force to the drone, in operational use, and the driving mode involves a more vertical orientation of the propeller assembly for allowing the respective propeller guard to drive on the railway track.
