Tata-ALLP Slot is good or may be a bit before TATA-ALLP in TATA-ROU direction. But in the ROU-TATA direction it must start after ADI Exp.
If you remember a special used to run with the rake of HWH-CKP Pass between CKP and TATA, that slop is good, as there is a huge gap between Ispat and Gitanjali in TATA-ROU direction during day time.
