These kind of RSA boards are confusing. Atleast in main boards the name and destination of that particular run alone must be mentioned. If possible other boards also must be flipped according to the train.
In that case the train will be full of boards.
I meant boards should be flipped according to its run. This is the case done with Karnataka Exp and Chennai Mail, etc. Hope you are clear now.
still confusing-need to do a proper analysis
this seems very easy to understand
