They're converting all to LHB within next few days it seems.
But for Kerala Express, the conversion of 6 rakes to LHB was in phases, leading to confusion due to variance in CC.
From next week on 16345/46 Nethravati Express too is getting converted to LHB; first rake will go LHB on 25/7, 2nd on 26/7, third on 28/7 and final rake on 2/8 I think.
