Great Idea to run pass train in KIK-TJ route. But using 16175 rake might not possible, since it reaches KIK @0745, and leaves @1600 as 16187 Tea garden express(Rake sharing).
So instead of 76813-76818(KIK-VLNK-KIK), run Kamban rake to VLNK, and return by 1400 or 1500 max, so that it will go as Tea garden express.
Now Use TJ-KIK DEMU, to TJ @915 and reaches @1230, return from TJ @1400 and reaches @1715.
Also...
more... we can use Kamban's VLNK slip rake to KIK, departs VLNK @1000 arrives KIK @1130. Starts to VLNK @1300 and reaches @1430.
