Some trains enjoy "unworthy" priority but some trains deserved to get priority.
Saampornakranti is 130 mps rajdhani standard, so needs best of the priority. Prayagraj is in its home zone NCR , so every train is "hero" in its home zone. Rajdhanis gang can't even be touched to give way. So in the end only those trains suffer who are not starting from NCR or ECR. The trains which are coming from other eastern places they suffer.
