Ideal Lineup should be KL-KK-TN and then SEB, as SEB has to travel only uptil RKMP and it has more halts in between but has a rather more aggressive TT then rest of the trains. SEB with 3 halts is faster than TN with no halts in VGLB-BPL section by 15 minutes, if TN departs after SEB then TN has to get trolled by SEB, but if SEB departs after TN then None of the trains has to be OTed and in result each of them can get speedup. Ideally SEB should depart from NZM at 10 pm and reach RKMP at 7AM and TN should have arrival at BPL at around 6:15 AM and Departure from NDLS at 9:30 PM, KK a little ahead so that it can avoid TN till Itarsi.
