Hundreds of passengers at the Indira Gandhi International Airport in Delhi and railway stations in the national capital were stranded after operations of flights and trains continue to be affected due to the dense fog. At least 62 trains in Delhi have been delayed, 20 rescheduled and 18 cancelled due to low visibility as fog continues to grip the region. Seventeen flights have been delayed at the Delhi airport, at the time of filing this report.

The air quality in the national capital has fallen under the 'very poor' category as the fog has not been allowing the particulate matter to disperse.

Yesterday, Northern Railway Chief Public Relations Officer Nitin Chowdhary told ANI that the Indian Railways has installed a fog-safety device in the trains to prevent long delays in winters.

Earlier on Tuesday, the Indian Railways has decided to extend the services of a few weekly special trains in order to clear the holiday rush of passengers and the inconvenience caused due to dense fog in the national capital region.

Hundreds of passengers at several railway stations in north India have been left stranded after multiple trains have been cancelled, delayed and rescheduled for the last couple of days. The weather condition is likely to remain the same for the next few days. -- ANI
