I have traveled a lot in this train. It is very well patronized and runs jam packed most of the day. It is used by daily commuters and hence you see a lot of availability when you check reservation availability. So, I don't think the train should be replaced due to reason being getting bad patronage from railways perspective. In fact, railways is making a lot of money from this train by charging daily commuters janshatabdi fare to all the daily commuters instead of a superfast/express second class fare which is almost double. So this is a gain for railways and loss for daily commuters.
