There were plans to extend Pune Duronto to MAO don't know what happened to it. But I feel route via SECR now would be bad considering the way they troll trains even Pune Duronto becomes victim.
Only present route to HWH looks better. This train should be made daily by giving a new slot and upgrading to SF by cancellation of slip, shifting LC to UBL and giving LHB rake thus 130 MPS in certain sections in HWH BZA.
