Here is the scenario sir actually the order from ET to NZM is 12615-12779-12621, 12621 has 4 halts between ET to NZM, 12779 has 5 whereas 12615 has more than 10. But the one to suffer is always 12779 somehow 12615 with twice the number of halts of 12779 and 12621 is always kept safe and 12779 is trolled.
Is this because 12615 and 12621 start from a Metropolitan city like Chennai and 12779 from a small city of Vasco ?
