-------Attention please----------
Dear friends,There are some questions/doubts arises in my mind:-
1. We generally see that when two train crosses(xing) each other, the loco pilot and guard of each train shares All Right signal with each other .Now my question is , if two train making crossing at a small non stopping station,is in this case they will share flag with each other ?
2....

We often see that when a train skips a station,it takes green signal from station master(generally a man standing with holding green flag and green torch in case of night).Now when two trains crossing each other how the station master will share flag with each other simultaneously ?
3. If the answer of the point no 1 is yes,then referring to the following image tell me the how station master and two trains will share their flag with each other simultaneously.
I will be thank full to those who will clear my doubts.
