The report says that the cost of building 42km line is 426cr in 2010 which includes land acquisition and RB asked to cut the costs and also avoid getting into Bannerghatta national park. Now in 2022 the cost of building 1km is 10-15cr and it cost around Rs 500cr without land acquisition cost. Pherpheral Ring road is proposed about 15+yrs and as state govt and BMRDA(or then organisations) could afford land acquisition was finally taken up by centre through NHAI and the cost is now around rs 200cr per km. So will the railways be spend hefty amount while state govt will not be able to spend on land acquisition.
