"The Airport Metro line would resume commercial operations at its regular timing of 5.30 a.m. from Jan 22 (Tuesday)," Reliance Infrastructure Limited (RInfra), which runs the line, said in a statement.
"It would run daily from 5.30 a.m. to 11.30 p.m. at a frequency of 15 minutes," it said.
The Commissioner of Metro Rail Safety (CMRS) last week gave clearance certificate to the swanky high-speed line, which took 18 minutes for the 23-km journey between New Delhi Railway Station to the Indira Gandhi International (IGI) Airport. The same journey by road would take upwards of an hour.
However, now, according to sources, the trip will take more time, as the CMRS has given permission to operate the high-speed line only at 50 kmph.
Before the service's suspension, the trains were running at a speed of 105 kmph.
