bihar mein chapra se rajdhani chalti hai via balia hokar

dimand to bhut train ka hota hai par koi gkp ko dhayan nahi deta hai.

as already discussed on this post, the GKP-LKO section is functional double line with mps over 100. the complete section between GKP and NDLS is double line.
So if the criteria of shatabdi and duranto is based on double line, i see no issue running shatabdi between GKP-CNB and a duranto between GKP-NDLS.

potentially, a duranto between GKP-NDLS and a shatabdi between GKP-CNB should be there.
and a rajdhani can be 'diverted' via GKP
