An Eye-opener data...
1) It's clear that Eastern Railway, NER, NFR & Kol Metro are the POOR PERFORMER in terms of Revenue Generation & also in REVENUE GROWTH during last three years..
2) If we ADD-UP the revenue generated by ALL ABOVE FOUR together, its LESS than the revenue generated by a relatively new neighbouring zone EAST COAST RAILWAYS !!!
In simple...
more... maths, Revenue of [ ER+ NER+ NFR+ Kol Metro] is LESS than that of ECOR, that's Unbelievable !!
3) NWR & SWR are other imp but less-performing zone in terms of revenue generation.
