Energy Saving of WAPs:
Figures available prove that on level sections, the loco generates around 10% of energy consumed and on graded sections up to 30%. As of now, 300 WAG 9, WAP 7 and WAP 5 locos running on the network annually save about 100 million units of energy, saving 105 tons of CO2 per annum.
Comparison with Rail road:
The SEC of...
more... WAP7 is around 12.28 units per 1000 gross ton KM (GTKM), where as for WAG 9 it is calculated as 6.63 units per 1000 GTKM which is 15 to 25% less than conventional locos.
A 12 T motor vehicle consumes 1 liter for 3 Km. equivalent to 27.7 liter per 1000 GTKM. Which means saving of Rs 1200 per 1000GTKM in WAG 9 loco hauled trains. Even if compared with diesel traction it saves Rs 100 per 1000GTKM.
