Abstract
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 (GW, GS) 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.

A method of operating a rail-guided permanent way machine, comprising the steps of:
- providing a rail-guided permanent way machine on a track,
- determining at least one state variable (Z) of the permanent way machine in dependence on an operating state, and
- comparing the at least one state variable (Z) to at least one pre-defined limit value (Gw, Gs) for monitoring the derailment safety of the permanent way machine;
- wherein the permanent way machine defines by means of at least one first measuring sensor at least one first measuring value from which a curvature parameter of the track is determined;
- wherein the at least one first measuring value is a swing-out path (SA) of a bogie (D1) of the permanent way machine.

- at least one first measuring sensor configured to determine at least one first measuring value from which a curvature parameter of the track is determined;
- wherein the first measuring sensor is configured to determine at least one first measuring value which is a swing-out path (sA) of a bogie (D1) of the permanent way machine.
