The report presents an analysis of the triggering of the emergency brake into safety loop of „Siemens Inspiro SF“. The activation of the emergency brake is analyzed depending on the state of the safety loop and its application in different emergency situations and damage during the operation. Safety loops are analyzed, drawing attention to the application of the emergency brake in a case of cutting off the safety loop, the circumstances and systems that could opened it as well as the various emergency train modes in which the embedded system for Telecommunication control of trains CBTC (Communication Base Train Control) is d to be switch off. The schemes are analyzed in cases of damage and circumstances where the CBTC system is d to be switch off, as well as safety loop and/or switch off of the trip cock.

The report does not address the loop of the traction lock, as it is a separate safety loop. When opening it, the train drive is blocked. The loop of the traction lock is related to other processes and circumstances, such as the state of the train doors - open/closed, the steering systems and does not directly communicate with the emergency brake.
