Keeping aside your "useful" point of views, I think, another angle of making a chain, is to aware people, that, there are these these & these ways...in addition to main route......till date, our dear members have prepared chains in the best possible ways between two important destinations. Now, still we are working on making chain, between those two important stations. So, naturally, distance as well as travel time and chances of getting seat will vary.....one more thing...
#Suggestion: People should keep flagging continuously, in all cases...including me.......all types of flags are welcome. Several times, I have seen that, after receiving one RED flag & "lambi chauri" explanation of providing that flag, by some dear member, other people used to stop flagging....
more... This should not be done, as per me. Everybody should mark their opinion.
