Actually INDB-MMR bhi zaruri hai, because this line will pass through Sendhwa, Khargone, which are mainly rural districts. As a result, intermediate villages will also get rail connectivity. Moreover, this region is rich in cotton production.
I agree that as of now, railways ko Mhow-Khandwa-Akola ko priority dena chahiye. This line will provide the shortest route to cities like Hyderabad, Bangalore and Chennai.
