Just I want to share a small experience when I was in primary school I used to go with my mother by Kanchanjangha express. That time it was a seater train and it was proving a service from Howrah to Siliguri/ Njp. From Malda it was a single line. If I am not wrong I can recollect it. So it is not the fault of Assam people not any northeast people. This zone have less income zone that's why they never give importance. Now the present situation compel the central govt to give importance . They feel this is the only route to connect mayanmar Bangladesh . So now developments starts.Hope this strategy will work. This will helps the northeastern people economic development.
