According to me the railway is thinking there is no demand but there is huge demand for this trains 22162/22161 and 12197/12198. The passengers are not booking ticket in this train but there is a lot of crowd who are college students, Up downers and many of the bank officials and businessman. I also sometimes travel in this train i didn't get place to stand in both of this trains. But the difference is that the people doesn't book tickets in this train as there are 2S coaches and people think that if TTE came then they will pay 10-20 rs. then this will allot them seat. Chair Car that is the point there is no demand of Chair Cars in this train and in this trains CC coaches run empty that is why railway thinking that there is no demand for both of this trains. The Fault is from railway...
more... also that TTE who have duty in 2S coaches doesn't come for checking and hence some passenger travel without ticket and railway thinks that there is no demand.
