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.

: But main issues of these stops is poor connectivity towards Delhi from Champaran Distt...I'm not justified the stops.
3 You have one of the best train "Humsafar" for Devi Patan Division for people of BLP, MUR, BRK which will also improve Tourism.
4.If you worried about poor people so please demand Frequency Increased to GKP-ANVT Weekly Express 3 Days from BLP and 3 Days from BST.You demand stop of most Packed Train on which People sitting in Toilets.
SF train Concept is introduce to cut Travel time...MP Demanding Stops will lead to convert it into Passenger Train.
