Machines can operate based on electricity received from a charging rail system installed along a route at a worksite. Sensors on the machines capture image data indicating locations and/or orientations of components of the charging rail system. Machine controllers of the machine, and/or a worksite controller, can monitor the integrity of the charging rail system by detecting possible faults if the locations and/or orientations of one or more components vary by more than a threshold amount from target locations and/or orientations. The machine controllers and/or the worksite controller can also initiate one or more response actions when a possible fault in the charging rail system is detected.
