Oh, for real? SWR only serves Tamil Nadu and Kerala? Just so you know, in the Chennai-Bengaluru line, there are only 4 SWR trains - 12027/28, 12607/08, 12609/10, and 12657/58. All the others are South Railways (SR). Trains like 16231/32, 16235/36, 16525/26 were introduced a long time ago and they are always packed, making it almost impossible to get confirmed tickets. The YPR-KCVL Garib Rath and AC Express are not daily trains. And you know what? There isn't a single dedicated train from SBC to TVC. Should SWR only run trains from SBC/YPR to different parts of Karnataka? Should they not run a single train anywhere else?

Oh, Really? SWR kewal TN aur KL ko hi satisfy karta hai? FYI Chennai Bengaluru line mein sirf 4 SWR trains hai-12027/28,12607/08,12609/10 aur 12657/58. Baki trains SR hai.
16231/32,16235/36,16525/26 jaisi trains to pehle se hi chal rahi hai aur woh bhi itni bhari hoti hai ke confirmed tickets milna almost impossible hai. YPR-KCVL Garib Rath aur AC express to rojgarh nahi hai. SBC se TVC tak koi dedicated train nahi hai.
Kya SWR sirf SBC/YPR se Karnataka ke alag alag hisse tak train chalaye? Kya woh kisi aur jagah pe ek bhi train nahi chalaye?

All the trains you mentioned are like dinosaurs, man! They were introduced ages ago. There ain't a single fresh train that came out recently. 17235/36 is not even a SWR train, it's a SCR train with a buddy called Seshadri Express. Even 11021/22 ain't a dedicated train to Tirunelveli, bro. It rolls in from Mumbai, you see. And 11005/06, nah, not a dedicated train to PDY either.
Talking about the SBC SA line, did you even think about 56241/42? That bad boy only goes up to SA in full SWR territory, man.
SBC and MYS division used to be part of SR, you know. That explains why those trains you mentioned, they're all ancient, dude.

KLBG, YG, and RC have train schedules 11311/12 and 16577/78. The 16577/78 train runs weekly but might become a daily service in the future. Additionally, RC and YG have another train schedule 16593/94.
UD has train schedules 16515/16, 16595/96, and 16585/86.
MAQ has daily intercity service, train schedules 16511/12, 16585/86, and even 16595/96, which is a good option since it stops at Surathkal on the outskirts of Mangaluru.
BAY has train schedules 06543/44, 16545/46, and 16591/92.
Despite the five zones, there is at least some connectivity. There are no trains from MAS to HSRA/DPJ.

KLBG, YG और RC के पास 11311/12 और 16577/78 sure 16577/78 weekly है, जिसे भविष्य में रोज़ाना बनाया जाएगा। अतिरिक्त रूप से, RC और YG के पास 16593/94 भी है। UD के पास 16515/16, 16595/96 और 16585/86 हैं। MAQ में दैनिक शहरी, 16511/12, 16585/86 और 16595/96 तक जाने वाली ट्रेनें हैं, क्योंकि यह मंगलुरु के आउटस्कर्ट सुरतकल पर ठहरती है। BAY के पास 06543/44, 16545/46 और 16591/92 हैं। पांचों क्षेत्रों में कम से कम कनेक्टिविटी है। MAS से HSRA/DPJ तक कोई ट्रेन नहीं है।
