Yeah 6.10-15 AM still seems to be kept reserved for a VB. That's a premium time for a premium train originating from NDLS. I think in future we may see this slot being allotted to a ASR/Punjab bound VB.
A 5.30 types departure, then stoppage at Sonipat & Panipat means Swaraj and VBs overtake will happen before Panipat itself and it also means that it is made to trail Ekta too.
While...
more... UMB arrival of Ekta is 9.30 and Swaran Shatabdi at 9.40 AM followed by Shan-E-Punjab and Kalka Shatabdi.
Essentially it will have to depart DEE something like 5.20 AM so that it is departing PNP by 6.35 AM in order to avoid trailing Ekta and arrives UMB right after Swaraj to escape Swarn Shatabdi and Kalka Shatabdi overtakes too.
