Translations:How to operate relay line block equipment/17/en

If the train has been through the block section and has passed our entry signal, it is now time to get active, so that we can release the line for the next train. In order to unblock (whiten) the end field (Ko), the following technical requirements are to be met:

• Our entry signal has been set to clear
• Our entry signal has reached stop position again
• if available: block section detectors do not indicate occupation of the track
• The train has cleared the overlap behind the entry signal
  • (clearance of the first track section behind our main signal will activate clearance indicator)
• the train has a tail signal
  • (the tail signal of the train does not have to be detected if the relay block is equipped with a track vacancy detection system)
• clearance indicator is lit
