Its a wrong belief that NTES got their own setup but "Schedule information captured in ICMS (PAM+COIS) is single entry for this information and the same data is populated to Control Office Application (COA) and National Train Enquiry System (NTES)"
click hereThe train ARR 52 Mins delay @ MV as per NTES & you!! I guess you highlighted PF variation but then, NTES is a display not source of info fed in Punctuality Analysis & Monitoring (PAM) at Div Level!!
