as per the TT in the TAAG, SC-Udhana is taking COA-LTT slot upto Pune which is 8PM departure from SC and 7:50 arrival at Pune which is a proper over night ....
the only problem in the return direction is on sunday morning from Pune, it have LTT-SC Duranto which depart pune 1 hour before this HS and a Shatabdi which departs close to 3 hours after ot departs Pune....to make it it wont hit the Duranto and Shatabdi occupancy, they intentionally slowed it down in such a way that it will arrive SC around 4-4:30 PM in the evening ...
if...
more... parking is no proble, they should have departed it on Friday fron Udhana so that it will arrive saturday morning around Duranto slot with little adjustements and in return on sunday already having pretty good slot...will see what's their plan is all about
