The line transferred is Manikpur (MKP) to Link junction (LKJN) near chheoki/ Naini.
The above section starts only 9 KMS from Allahabad junction and if some disruption happens here, Jhansi is much far (~300 KMS) and from there official cannot reach faster (on time) as compared to officials from Allahabad which can come within 30 mins.
This may be the reason!
