LTT can accommodate this. When CSTM can hold NCJ CSMT for 1-1/2 hours, LTT can coolly hold SBC LTT UBL train for 2 hours. Also, from DR, there is a train at 2130 (Chalukya/ Sharavati).
PM should be at UBL. Round trip UBL LTT SBC LTT UBL Nearly 4000 kms. SM can be at SBC/ YPR on completion of 2000 kms (UBL LTT SBC).
But bus lobby ?? !!.
If...
more... such a proposal gets approved, daily train to Mumbai can run. For time saving, if needed it can run from LTT via SUR RC also (distance less by 100 kms and 1-1/2 hour journey time saving), by following SUR SF. KLBG gets a daily SWR SF in that case.
