Yes, it is necessary because Gonda Jn is the head quarter of Devi Patan Division. Not only from Gonda but also people coming from BLP, MUR, BRK and other places to travel in these trains beacause it is central of Devi Patan Division.
You are talking about demolishing of these trains is just laughable beacause these trains halted at less facilitate and halt stations.
On other hand Gonda Jn has more facilities like loco change,watering,catering and many others comparing to other halt station.
And...
more... last, Humsafar have flexi fare and also have more valuable ticket of 3A but we are thinking about every types of people.
I hope you may understand what i want to say.
