I have observed change in mindset of NCR from last one month's. Approximately all trains are treated with their own schedule and also NCR don't hesitate to looped their prestigious train 12417 & 12451 to providing overtakes by other zones trains like 12381, 12801, 12397, 12565, 12555.
Attached is the screenshot of two 130 mps trains. Both covers cnb to ndls in around 5 hrs that is 12801 & 12397.
