No way it's a safe connection. Avg Delay of VB at NDLS is 8mins n it'll arrive on some Pf in between moreover it's peak time both Paharganj n Ajmeri Gate side will be blocked by incoming taxis not so easy to book/reserve a taxi n same goes for NZM . Dargah side has till now n it's always packed with buses. 1hr 15mins is a big no.
