I don't have data in terms of kW-h saved but in terms of capital cost recovery (discounting interest & maintenance and running costs), a WAP 7 locomotive is able to pay off itself in about 8 years. Means assuming fixed cost of electricity tariff (~ ₹ 6.40 per kW-h), WAP 7 (with transfer cost of...

That is true, but you have to account for changes that India too would be going in terms of its fleet size and quality. by 2030, we are expecting AMCA and large number of Rafales along with one more VLO aircraft in Indian Inventory along with much superior AWACS and ground based Radars. The...

Could well be!

Just 2 things, i'm not sure if J 20 is a game changer yet. It isn't battle proven and more importantly nobody knows (based on information available on open forums) of its RCS and effectiveness as an integrated weapon system. I would be more concerned with asymmetric fleet size of Indian and...

Bilal Bhai, i'm not sure what kind of wagons BD Railways is purchasing but given same track gauge size (1676 mm) and about same axle rating (~ 20Tons per Axle) in Bangladesh, there should not be much problem for Indian Coach makers to make such wagons. Here is how LHB (which BD railways) is...
