Will be the worst decission. As a regular in this and guj mail, the basic diff is, people who want to go to bvi/adh/dr prefer mail. Remember those 8 3ac and 3 2ac coaches, they are always packed with north mumbai peeps, apart from those who caught from anand or nadiad for bct. Otherwise all proper city peeps travel in 12268. There are rarely any passangers of bvi/adh in duronto train, as they take mail. So pls let this classification be there. City travellers don't want to wake up at 5.20 am half and hour early with the undue disturbance. I put this as a regular traveller on both the trains. So pls maintain the sanctity of the situation. If someone wants to go to bct or adh or dr, pls take mail, its equally good.
