Uday overnight ac DD chaircar trains shall have fate similar to Yuva Express trains.
Yuva express trains (Del-Mum/Kolkata) with only ac chair car coaches were a blunder (poor patronage on high demand routes in spite of super duper speed)which saved their face through introduction of ac sleeper years after their introduction.
over night ac DD chaircar UDAY trains shall save face by running in day time instead of night.
