There should be a bit of innovation in introducing VBs now.
For example, they should join 3 8-Car Vande Bharat trains and start it as single train from NDLS towards Punjab/Haryana side, say at 6 am in the morning.
It...
more... should reach UMB at 08:10
From there first VB moves to BTI via Patiala at 08:15
Second VB moves to ASR via LDH JUC at 08:20
Third VB moves to KLK via CDG :0825
They need not be attached at UMB while returning.. they can reach Delhi as per their own timings and get attached in NDLS yard during the night for next day's journey.
Another similar set can be NDLS -LDH moving towards JAT, ASR, FZR respectively
