Very very Interesting, I was searching for similar steps in IR from long time.
Hope IR implments the same very soon or at least start the process of finding commited vendors, funds allocation, damage resistance techniques for the rooftop equipments on coaches that can make the plan futile.
Just Imagine 90000 Ltrs per rake per year i.e. we in india have close to 6000 trains means aprrox. 18000+ trains.
A...
more... leyman's calculation shows 90000x18000= 1620000000 i.e. 162 crore Ltrs diesel, considering 1 Ltr diesel costs IR = 55 INR, then it becomes 162x55= 8910 Crores!!!
In 3 years IR will be 100% surplus company!!!
Besides that 1 rake doing 188 trips an year can avoid 239 tonnes of CO & CO2 emmission, there by reducing carbon foot print...awesome!!!
--------------------------
Well if we take 40% efficiency of this theory of IISc also, then the savings becomes 8910 Crores x40/100(%)= 3564 Crores a year.
So instead of 3 years let it take another 3-4 years i.e. in 7 years we reached the BREAK EVEN and became a 100% revenue surplus company.
2014-2021= That's 7 years!!!
And a 100% surplus IR means, no budget allocation needed in Centre for IR and that 20000 Crores of it in budget can be diverted to Agriculture, irrigation, general healthcare, education & infrastructre investments.
So in other words a very good idea, Hope Modi Ji and SN Gowda ji think of implementing it.
