Useful. There is a scope of 15 minutes speedup without any slack removal, if slack is adjusted then 25 minutes speedup is possible
5 minutes halt should be reduced from both ET and JBP no need of 10 min halt, crew change and Food Loading can be done in 5 minutes. So 10 minutes can be saved here, 10 minutes slack can be removed from JBP-ET section and 5 minutes from JBP-STA section. But I guess this would be too much to ask for, as of now 15 minutes speedup is easily possible. After ET-JBP-STA 130 kmph 30 more minutes can be saved.
