which rule book of IR says that LHB should get precedence over ICF train ? Brahmaputra Mail isn't a crawler, the gap between mail and purushottam was of just 10 kms when mail was at ftp and puru was at fyz after that puru had a halt at ftp whereas mail got priority and gap increased to 50 kms. and yesterday BP Mail was the only train among SF/Mail/Express which overtook many freights. even purushottam overtook freights but pf unavailability at CNB made puru to wait at outer whereas mail being mostly on time received good priority and purushottam being late @ CNB by hour got less priority being an off-track train.
call it biased or whatever you want.
