Remind me again Joe where is the world ranking of your alma mater compered to mine these days?

I think to have a good comparison between WAG 7 and WAG 4, you need to factor the revenue into the calculation. We can do a basic payback period calculation, which has:As i keep thinking often @Joe Shearer , Sir you have to teach us kids a lot of things.
Coming to the question of @Nilgiri , it is rightly pointed out by Joe Shearer that locomotive is cost and here in context of repayment, we are actually comparing it with a locomotive that doesn't put back energy in system where it is being fed in first place. I'll try to put in terms of figures:
Let us assume it is 2015-16 (last year of WAP 4 and WAG 7 production). That time WAP 4 costed Rs. 7.9 Crores and WAP 7 Rs. 12.40 crores.
So let us take case of a WAP 4 and a WAP 7 produced that year. Assuming same running utilization (that is service hours) a WAP 4 would not have returned any power but a WAP 7 would @ Rs. 50 lakhs per year (this is an assumed value based on following formula
Rated power of WAP 7 4,500 kW
Number of days of operation in a year 300 days
Amount of time in day when using power 33%
Power Tariff (Averaged) Rs. 5.50 per Kw-H
Amount of power returned back 15%
Total amount of savings by power regenerated = 4,500*24*300*0.33*0.15*5.5 = Rs. 88, 20, 900.00 say Rs. 90 lakhs.
So in about 5 years loco would have earned around 4.5 crores that a WAP 4 would not have, had it been in operation in place of WAP 7.
These figures vary (especially that availability time on track) but can give you a rough idea of how economics of operation is like.

Its about 60 lac now a days@jbgt90
Just read this post and learn how modest and decorous, and to the point, he is. No bragging about being an ISB grad., nothing about doing in one year what we poor bozos had to do in two, just straight to the point!
And nothing about degrees and diplomas either.
I hear the going supari for senior government officers is Rs. 2.0 lakhs. Hmm....now that's a thought.
This is what we need you here Anant bhai!!! you are a mine of information .As i keep thinking often @Joe Shearer , Sir you have to teach us kids a lot of things.
