प्रयागराज एक्सप्रेस - जो भी हो तुम खुदा की कसम; लाजवाब हो

Just spotted an empty rake set of Tejas Chair car coaches crossing from Unnao (ON) going towards Lucknow/Aishbagh
Any idea where these Coaches are going?
I spotted this train containing 16 coaches of Tejas Chair Car nearly at 8:45 in the morning.
