Yes. You're right. There are some 2024 mfd coaches attached. But other coaches are mfd in different years, which were already used by the other trains.
From this train's POV, they are old coaches. This is what I meant to say.
Many trains are getting newly mfd LHB Coaches during the conversion. But this train got old-new coaches. Atleast for the sake of inaugural run, they should have attached all the 2024 mfd coaches.
