Might be a vague idea...but just wanna put it front...
Why cant this train be extended till Vijayawada😉
As the rake is lying idle frm Morning 5.00am to Night 11.00pm in Chennai, they...
more... can extend it till Vijayawada via Perambur or even MAS should be fine i believe.
TT would be some what like 5.00am MAS, 9.30am OGL & 11.00 am BZA
Return this can start by 16.30 BZA, 23.00 MAS
This can become a good daily to SBC for AP ppl
**can be routed through GNT by adding 40 mins to schedule for more pax
