(2) System of accounting and data generation in IR is far from perfect, and often give partially correct/ incorrect picture, which is one of the major reason why innovative policies implemented by IR often fails due to wrong market assessment/calculation.

So you will always find that the many relatively smaller towns with Div/zonal HQs have much more number of originating trains and much better station amenities, more and longer train stoppage etc. than other towns of same or even higher status.

(5)This becomes a vicious circle and more and more proposals of new trains, capacity augmentation etc are made which are centered around HQs rather than actual traffic centres, much to the convenience of the officials based in HQs and inconvenience to the masses residing in the bigger traffic centers.
