my small request is don't blame the divisions.lets consider as you said..why waltair division officials initiate the zone level converstions. they can negotiate right at zone level. pls analyse the past 10 years history.Guntur division having single track. it's almost congested.if you observe properly no new slot created in the division judiriction . new trains running on sharing the exsiting slots. i heard same situation for BZA also between NDD to SLO.looks like railwayboard need to allocate more fund and SCR also should focus on this with high priority.
