Ok lot of thanks now it's clear to me it's really a long time question why some of the trains in ER ,ECR and NCR is not allowed to do 130.Even in WR trains like Saurastra Mail(having short distance),Paschim Express, Sayajinagri, Dadar-Bikaner Express , Kutch Express these all trains are not allowed even in NWR trains like Mandore , Ashram , Yoga are not cleared 130 . I have heard that Paschim doesn't have 130 TT. Ok many many thanks for clarifying the reason.Can you say why Brahmaputra mail,tata-jat and sbp-jat is not cleared for 130 in NCR?And even I have seen in SER and ECoR all trains are permitted for 130 but sometimes when trains are hauled by SRC WAP-4 or HWH/GZB WAP-5 they doesn't perform 130.Why these?
