Replacing sleeper coaches with 3rd AC coaches sounds feasible for Purvanchal express but why this siyappa with 15009/10..At least They should introduce 2 separate rakes for 15009/10 with at least 6GS,8SL ..From MLN to LJN this train is not even 15% occupied,I witnessed this multiple times.Unreserved passengers travel in SL because there are only 2General coaches.15009/10 was good when it doesn't have RSA with Purvanchal express.
