Nordex Alpine – door systems status.  

All rail mechanisms are seated and operational; tested panel movement from -50m to -120m without abnormal resistance. One of the upper tracks had slight misalignment, corrected with calibration wedges — tolerances now within spec.  

The double-panel reinforced doors are heavier than anticipated; six operators moving manually were able to shift some parts, but we’re relying on full automated rails for routine operation. Locking nodes are engaging smoothly with wall-integrated control units; no binding detected.  

Minor vibrations from tunnel excavation are noticeable, but stress sensors on the plates show tolerances are well within safety parameters. Doors are silent enough when moving slowly; a moderate speed test produced a satisfying controlled “thump” on the stops — reassuring, but not too harsh for the underground structure.  

Next: I’ll monitor door hydraulic response under continuous cycles overnight and log any deviations.  

End of transmission.
