VSG-HYB/TPTY express already runs on Fridays, just before Amaravathi. KCG slip should be cancelled, VSG-HYB should be made in to a dedicated train 4 days a week and TPTY train can be scheduled on some other time/day wherever slot is available.
Amaravathi coaches are absolutely terrible in current state, not to mention given the distance it covers, it needs a speed-up and upgrade to SF in addition to LHB rakes.
