Most Humsafar Express oh seriously! My routes have 3 HS. Nizamuddin-Durg, Tirupati-Jammu Tawi, Nanded-Jammu Tawi all are flop You talk about Humsafar huh!
And i believe political halts and trains have came more in fashion from last 5 years. And talk about traffic survey, When already a slot packed trains are running between bhopal to delhi in night hours another train is introduced with High speed and sleeper coaches and few people want their train to run over existing high speeds.
Why cant...
more... they run in existing slot? which is completely empty and can be run easily without any clashes! This is my information and i hope correct.
