in Indian standards, some locos's class don't have relative Horse Power.
For example, WAG-6A,B n C, the forefathers of this new family, have 6380 HP, which is actually mentioned as 6100 or 6000 in many sites, but they have 6380 HP.
The makers at ASEA Brown Boveri have planned accordingly with class name as per Indian standards.
That's why its known as...
more... WAG-6 with 6000+ HP.
If IR had followed its class style, then WAG-9 would b 9000 HP unit. and WAP-7 would 7000 hp.
