A rail-guided permanent way machine is operated by means of a control device in such a way that at least one state variable (Z) of the permanent way machine is determined in dependence on an operating state, and the at least one state variable is compared to at least one pre-defined limit value (G.sub.W, G.sub.S) for monitoring a derailment safety of the permanent way machine. Thus, the derailment safety of the permanent way machine is determined in accordance with the current operating state and monitored. As a result, the permanent way machine has an expanded operating range and increased performance and thus increased efficiency.

Method of forming track section includes coupling functional components to a framework. At least some of the functional components are arranged in a precise and accurate arrangement in a common plane. Building a rigid, removable, and reusable mold around the framework and functional components. Steel reinforcement (“rebar”), which is bent into a shape corresponding to a track section profile, is provided within the mold. Dispensing a binder material into the mold and curing the binder material; and removing the mold from the cured binder material to reveal a completed track section at required accuracy set by the framework. At least some other functional components are arranged parallel to each other in a first lateral plane normal to the common plane and at least still other functional components are arranged parallel to each other in a second lateral plane normal to the common plane and parallel to the first lateral plane.

The disclosure describes a sample confinement tool that includes a first end and a second end. The first end of the sample confinement tool is coupled to a driving tool. The driving tool is coupled to a heavy-duty vehicle. The sample confinement tool is operable to insert a predetermined depth below a ballast surface and collect a ballast sample within the second end of the sample confinement tool. The sample confinement tool is also operable to confine the ballast sample within the second end of the sample confinement tool by mechanically compressing the ballast sample. The sample confinement tool is further operable to release the ballast sample into a sample receptacle by mechanically decompressing the ballast sample.

The invention is a system and method for repairing, improving, and stabilizing subgrade and subsoil/natural ground layers of a rail bed generally consisting of softer soils. One embodiment includes a method of installing subsurface inclusions and ballast fills comprising injected slurry mixtures of stabilizing material such as cement grout mixed with in situ soil. Another embodiment includes a system of installed ground inclusions and ballast fills. Another embodiment includes an integrated system of equipment for emplacing the system of inclusions and ballast fills.
