If a ICF sleeper rake able to reach BZA in 4 hr 10 min. What about all AC LHB trains ??
So a good high speed shatabdi express needed in this route...so that it help to reduce the pressure on NH9.
If Shathabdi can start from Lingapalli with stops Begumpet, Secunderabad Warangal its enough.
Lingampalli - 17:15
Begumpet...
more... - 17 :48
SC - 18:02 - 18:10
WL - 19:50
BZA - 22:20
Sure many prefers it over bus.
