The absolute beauty of GC. 12274 which was diverted departed ddu with a delay of 4 hrs 37 min but still reached asn with a delay of 1hrs 47min. Won't say that the run was of duronto standard taking 6hrs 30min but still the difference between GC and main line is depicted from this run. GC where the slack is almost negligible for any train and main line where slack is given in kilos to maintain the punctuality index. No wonder why this section can boast of good punctuality among the whole ECR.
