In Indian Railways, we have calling on signal movement. Normally calling on signal provided below the main signal. Whenever main signal fails to clear for the following reason, signaller will give calling on signal route.
a. Main signal is not showing off aspect because of signal in advance is blank.
b. Main signal all off aspect are (Lamp) failure.
c. Main signal route indicator is failure.
d.Overlap point is failure to operate.
e. Signal control track circuit is / are failure.
In this condition signaller will give Calling on Signal route. In Interlocking logic also we are providing calling on counter. Whenever calling on signal given, calling on counter will get increment one.
So the signaller will register the calling on signal clearance purpose with calling on counter number and the reason.

In GK/RT0044 , sec 4.1.2 has the following wordings.
"At each location where facilities are provided to signal trains onto Occupied Lines, the Infrastructure Controller shall specify and document the particular purposes for which those facilities are permitted to be used, and shall ensure that they are not used for any other purpose."
In this i am not able to understand about the facilities & what it is referring for. Is it referring to the signalling equipments?. Also why the facilities are not used for other purposes?. Kindly clarify.
