Please don't adhere to any TT update request for 12344 originating from HDB. 12344 originates from NJP only, the TT in between HDB and NJP is actually the TT of the connecting passenger train 55752, which carries only 4 coaches for 12344 to be attached at NJP. Thus the HDB-NJP stretch should not be included in 12344 TT. Better to create a separate TT for 12344-Slip.
