A rail tool-holder cart (1) comprises a T-shaped support frame (2), a tool-holder arm, (12) rotatable about a vertical axis and tiltable between an upper position and a lower position and having a coupling interface for a tool (17, 17), a spring (19), which pushes the tool-holder arm permanently towards the upper position, so as to compensate at least one part of the weight of the tool (17, 17), as well as adjustment means (20) for adjusting the spring thrust (19).

A composition for increasing adhesion between two surfaces that are in traction, sliding or rolling-sliding contact with each other is provided. The composition comprises one or more than one first component, where each of the one or more than one first component has a Mohs hardness value of equal to or greater than 7, and one or more than one organic rheology additive. The one or more than one first component and the one or more than one organic rheology additive are present in a ratio from about 90:10 to about 99.9:0.1 (wt/wt). The composition does not comprise water. A method of increase adhesion between two steel surfaces in sliding-rolling contact is also described. The method involves applying the composition to the rail surface at a rate sufficient to increase the adhesion between the two steel surfaces.

A machine for track maintenance is manually displaceable on a track. The machine has a work module with a handle, a working tool powered by a drive and a machine frame configured to be guided on a rail of the track. The work module is detachably connected to an energy module and the energy module has an electrical energy store and output contacts. The output contacts are detachably connected to input contacts of the work module. The work module has as the drive an electric motor supplied with electrical energy from the energy store. This solution results in a high degree of overall efficiency because the energy available in the energy store serves for the largest part for covering performance peaks.

A device for in-situ, dynamic repair of a railroad can include two connected machines. A first one of machines can be a track lifting unit that can clamp the rails of the railroad and lift the track in its entirety out of its track bed. The first machine also can plow ballast away from and/or toward the rails, and level the track bed for the rails before they are lowered. In addition, the track lifting unit can remove selected railroad ties. The second machine can include a power unit that can provide hydraulic, pneumatic and electrical power to both machines. The power unit also can provide track stabilization by settling ballast and can free debris from the railroad while it is raised.

A railway track trolley includes a pair of carriages and a workhead mounted to at least one of the pair of carriages. The carriage is adapted to locate on one of a pair of railway track whereas the other carriage locates on the other railway track. The carriages are interconnected via a coupling assembly to permit independent sliding of the carriages relative to one another. In operation, at least one of the carriages is moved along the corresponding railway track wherein its associated workhead is adapted to implement work at that railway track.

A cribbing vehicle is provided that includes a vehicle frame and a primary cribbing device coupled to the vehicle frame and having a work head may move between rails of a track. The cribbing vehicle may include an auxiliary cribbing system removably coupled to the vehicle frame in spaced relation to the primary cribbing device and having a push arm may move between a first tie and second tie of the track.
