Intended Use and Function

Reversing loops and wye junctions inescapably produce a short circuit at the entry or exit points. There-
fore these arrangements require to be electrically isolated at the entry and exit points. To facilitate a
reversing loop operation a module is required to take care of the polarization of the loop section.
It is also RailCom
®
from the terminal loop.
The terminal loop module provides numerous operation modes:
▪ The use of additional "sensors" enables the Z21
multi LOOP detects the polarisation of the entering train and adjusts the polarity of the reversing loop
section accordingly before the train enters the loop.
