Could you explain about Multi relay track circuit and in which case it has to be used?
Do you mean
a) a track circuit having a second relay at the feed end as well as the main relay at the other end, or
b) a long track circuit that is one section to the signaller but for functional reasons has to be composed of several separate ones actually trackside?
Yes, Please explain about item (a)
