At least 81 Delhi-bound trains have been delayed, 21 rescheduled and three cancelled due to dense fog in the national capital on 7 December.
Eight international flights were delayed, three diverted and five domestic flights were also delayed due to poor visibility.
However, the Delhi International Airport Limited (DIAL) had yesterday announced its preparedness in tackling fog at the IGI airport.
According to media reports, three runways at the IGI Airport - 28, 29 and 11 - are certified for CAT III B operations, which would allow landing of the compliant aircraft with visibility as low as 50 metres, while an aircraft can take off with visibility of 125 metre.
The Met has predicted that New Delhi will continue to reel under dense fog this week.
