For a RailFan, watching MPS skips are far more interesting than watching F1 race - Prince Maan

Proposed timings are definitely useful for nandyal bound travelers.

There might be 2 issues with this
1. Availability of early slot at YPR ( proposed slot is tightly chasing 12785)
2. Will SWR agree...

to keep rake for extended time at ypr? May be return time needs to be preponed or it needs to be extended

TN bound trains have long stationary timings at YPR-SBC. SCR shouldn't be a zone serving long bound trains.
Apart from Seshadri there should be 2 more daily trains starting within AP.
(Kondaveedu,Vskp another daily to SMVT)

YPR...

can shift long bound trains like Sanghamitra,GKP,Kaziranga to SMVT and allocate space for trains with distance less than 1000kms travel.

Getting special preference for Tamilnadu bound trains at bangalore is altogether a different story. Many officials in SWR belong to TN and that could be one of the reasons.

For long time, SWR is serving different states. Just think UBL-SBC is not FEDL so far. Things are getting changed now-a-days and more intra state trains are getting started.

think getting trains to Bangalore is easy via DMM route considering SR is not involved . Having said that most of the stretch (complete) GY-YNK is getting doubled, higher chances for introducing new trains. Again, something needs to be pushed at SWR to accept more trains. For example, parking trains at Chikkabanawara/Whitefield etc. It needs some pragmatic minds to think positively. Again, we also should think not all trains can be accommodated in the morning and leave bangalore in the evening.

Note: DHNE-GNT single line will still be a bottleneck
