The Minimel Lynx warning system warns people in the vicinity of the track of approaching trains. In automatic operation as an "Automatic Track Warning System" (ATWS) the train movements are detected by means of rail contacts connected to a transmitter HSF-L. The transmitter transmits the train movement by radio to the EZE-L control centre, which triggers the acoustic and visual warning. The departure of the train from the construction site is detected manually by the safety attendant at the EZE-L control centre or automatically by means of a rail contact.
Minimel Lynx is typically used as ATWS on construction sites with a spatial extension of several hundred metres. In the case of track renewal, it is also used on construction sites with a much larger extension, which are then divided into individual warning sectors several hundred metres long.
